Hi, I am a Javascript apprentice. Can you help me with my project?
- Sure! What do you need?
Oh, it’s very simple, I just want to make a static webpage that shows a clock with the real time.
- Wait, why static? Why not dynamic?
I don’t know, I guess it’ll be easier.
- Well, maybe, but that’s boring, and if that’s boring you are not going to put in time, and if you’re not going to put in time, it’s going to be harder; so it’s better to start with something harder in order to make it easier.
You know that doesn’t make sense right?
- When you learn Javascript you’ll get it.
Okay, so I want to parse this date first to make the clock be universal for all the regions.
- You’re not going to do that by yourself right? You know what they say, don’t repeat yourself!
But it’s just two lines.
- Don’t reinvent the wheel!
Literally, Javascript has a built in library for t...
- One component per file!
I’m lost.
- It happens, and you’ll get lost managing your files as well. You should use Webpack or Browserify for managing your modules.
Doesn’t Javascript include that already?
- Yes, but some people still have previous versions of ECMAScript, so it wouldn’t be compatible.
What’s ECMAScript?
- Javascript
Why is it called ECMAScript then?
- It’s called both ways. Anyways, after you install Webpack to manage your modules, you still need a module and dependency manager, such as bower, or node package manager or yarn.
What does that have to do with my page?
- So you can install AngularJS.
What’s AngularJS?
- A Javascript framework that allows you to do complex stuff easily, such as two way data binding!
Oh, that’s great, so if I modify one sentence on a part of the page, it will automatically refresh the other part of the page which is related to the first one and viceversa?
- Exactly! Except two way data binding is not recommended, since you don’t want child components to edit the parent components of your app.
Then why make two way data binding in the first place?
- It’s backed up by Google. You just don’t get it do you?
I have installed AngularJS now, but it seems I have to redefine something called a... directive?
- AngularJS is old now, you should start using Angular, aka Angular 2.
But it’s the same name... wtf! Only 3 minutes have passed since we started talking, how are they in Angular 2 already?
- You mean 3.
2.
- 3.
4?
- 5.
6?
- Exactly.
Okay, I now know Angular 6.0, and use a component based architecture using only a one way data binding, I have read and started using the Design Patterns already described to solve my problem without reinventing the wheel using libraries such as lodash and D3 for a world map visualization of my clock as well as moment to parse the dates correctly. I also used ECMAScript 6 with Babel to secure backwards compatibility.
- That’s good.
Really?
- Yes, except you didn’t concatenate your html into templates that can be under a super Javascript file which can, then, be concatenated along all your Javascript files and finally be minimized in order to reduce latency. And automate all that process using Gulp while testing every single unit of your code using Jasmine or protractor or just the Angular built in unit tester.
I did.
- But did you use TypeScript?37 -
Testivus On Test Coverage
Early one morning, a programmer asked the great master:
“I am ready to write some unit tests. What code coverage should I aim for?”
The great master replied:
“Don’t worry about coverage, just write some good tests.”
The programmer smiled, bowed, and left.
...
Later that day, a second programmer asked the same question.
The great master pointed at a pot of boiling water and said:
“How many grains of rice should I put in that pot?”
The programmer, looking puzzled, replied:
“How can I possibly tell you? It depends on how many people you need to feed, how hungry they are, what other food you are serving, how much rice you have available, and so on.”
“Exactly,” said the great master.
The second programmer smiled, bowed, and left.
...
Toward the end of the day, a third programmer came and asked the same question about code coverage.
“Eighty percent and no less!” Replied the master in a stern voice, pounding his fist on the table.
The third programmer smiled, bowed, and left.
...
After this last reply, a young apprentice approached the great master:
“Great master, today I overheard you answer the same question about code coverage with three different answers. Why?”
The great master stood up from his chair:
“Come get some fresh tea with me and let’s talk about it.”
After they filled their cups with smoking hot green tea, the great master began to answer:
“The first programmer is new and just getting started with testing. Right now he has a lot of code and no tests. He has a long way to go; focusing on code coverage at this time would be depressing and quite useless. He’s better off just getting used to writing and running some tests. He can worry about coverage later.”
“The second programmer, on the other hand, is quite experience both at programming and testing. When I replied by asking her how many grains of rice I should put in a pot, I helped her realize that the amount of testing necessary depends on a number of factors, and she knows those factors better than I do – it’s her code after all. There is no single, simple, answer, and she’s smart enough to handle the truth and work with that.”
“I see,” said the young apprentice, “but if there is no single simple answer, then why did you answer the third programmer ‘Eighty percent and no less’?”
The great master laughed so hard and loud that his belly, evidence that he drank more than just green tea, flopped up and down.
“The third programmer wants only simple answers – even when there are no simple answers … and then does not follow them anyway.”
The young apprentice and the grizzled great master finished drinking their tea in contemplative silence.

Came home late last night and told my wife I'm skipping dinner to take a 1hr nap as it's going to be a long night of bug fixing and testing. Woke up, my wife and 1yr old son are already asleep. Saw the pic below posted on the wall above my work area at home. She's a teacher, she's never heard me mention it, and I don't use this method (I prefer music on my headphones). But she does know I lurk devrant so she must've browsed here while I was napping. Feels good. Code fixed, checked-in, unit tested and released for user testing.

We have this stupid library at work. Its called Randomness, and its basically just a wrapper over the standard .NET System.Random class to help our devs generate random data for unit tests easier.
Debate about random data in unit tests aside.
I came across a bug in randomness. Theres a PickFrom function which gets passed an array, and returns a random element from the array. Problem is, it uses Random.Next to do this, and the max value was set to the array length, minus one.
Random.Next generates values inclusive of the min value, and exclusive of the max value. Arr.Length-1 as a max value, is wrong, the last element in the array would never be selected.
So i fixed it.
And proceeded to break dozens upon dozens of unit tests that were now testing from their full sets of data, and had actually been faulty for god knows how long.8 -
The moment I dared ask a colleague about unit testing, and instead of giving me a book or a look, he stashed his work, pulled over a second chair and we coded some, for an hour.3

Been lurking here for a while. Finally pissed off enough to post.
Been programming in Ada for nearly a decade now. One of the few younger devs who knows the language well. Have a large collection of libraries and tools written in it, open source. Done contract work. Looking to get out of my current line of work, which is medicine, because fuck this recent legal climate. I'm spending all my time dealing with legal compliance and it rapidly changing.
I see a job posting from a company looking for a programmer to mostly write testing stuff for clients. They mostly work with Ada. I've written a whole unit testing and integration testing framework. Perfect. Apply. "You don't have the required skills." Oh... K then.
Wanna guess what I was just offered as contract work. Same company. I guess i'm fucking qualified if you asswipes sought me out to ask me to fix your fucking bullshit.
What the hell is wrong with management and HR in recent years?9 -
Rant.😒😡😠
I'm a college drop out. Left my college almost 1 year ago, taught myself php, js, nodejs, basics about servers and how it all works, currently learning angular, nativescript and a few small things.
People still taunt me about leaving my college. About how I should've at least completed my degree.
Student of my university don't even know how to code.
Like they only know simple hello world programs.
They have no idea about :
-Version control system
-Unit testing
-Code refactoring
-Cross-platform app development
-web hooks and REST API
-Stack overflow (Yeah, they don't know about it)
-and a whole ton of small things that you MUST know as a computer engineer like e.g. how to use Vim
I keep getting nagged about my choices and it frustrates me that I can't explain it to them cause they're dumb.
I mean seriously people! Can't you see the difference between me and an engineer who doesn't even know the difference between API and IDE?
I mean seriously?
They say it's APPLICATION PROGRAMMING INTERFACE so it's Qt creator or [any other IDE]
How can I deal with this kind of nonsense?
I'm from India, it's that bad here.
Anybody else a drop out? How did you handle it?
My parents are supportive but they too sometimes worry.69 -
Not so much screaming as staring in disbelief, mumbling profanity in his direction...
When my department lead said "I don't think this unit testing hype or code reviews make much sense, it's more efficient to just make a checklist and test the application yourself"
This was the QA department of an aerospace company, we wrote NDT software to do image recognition on xrays of alloy welds and micrometer laser measurements on fuel tank surfaces. Software which is quite mission critical, a single misrecognized welding fault could literally cost up to half a billion dollars — not to mention that it's a very sabotage & espionage sensitive industry.
After raising some hell he was replaced though.3 -
Imagine if a structural engineer whose bridge has collapsed and killed several people calls it a feature.
Imagine if that structural engineer made a mistake in the tensile strength of this or that type of bolt and shoved it under the rug as "won't fix".
Imagine that it's you who's relying on that bridge to commute every day. Would you use it, knowing that its QA might not have been very rigorous and could fail at any point in time?
Seriously, you developers have all kinds of fancy stuff like Continuous Integration, Agile development, pipelines, unit testing and some more buzzwords. So why is it that the bridges don't collapse, yet new critical security vulnerabilities caused by bad design, unfixed bugs etc appear every day?
Your actions have consequences. Maybe not for yourself but likely it will have on someone else who's relying on your software. And good QA instead of that whole stupid "move fast and break things" is imperative.
Software developers call themselves the same engineers as the structural engineer and the electrical engineer whose mistakes can kill people. I can't help but be utterly disappointed with the status quo in software development. Don't you carry the title of the engineer with pride? The pride that comes from the responsibility that your application creates?
I wish I'd taken the blue pill. I didn't want to know that software "engineering" was this bad, this insanity-inducing.
But more than anything, it surprises me that the world that relies so much on software hasn't collapsed in some incredible way yet, despite the quality of what's driving it.51 -
Senior development manager in my org posted a rant in slack about how all our issues with app development are from
“Constantly moving goalposts from version to version of Xcode”
It took me a few minutes to calm myself down and not reply. So I’ll vent here to myself as a form of therapy instead.
Reality Check:
- You frequently discuss the fact that you don’t like following any of apples standards or app development guidelines. Bit rich to say the goalposts are moving when you have your back to them.
- We have a custom everything (navigation stack handler, table view like control etc). There’s nothing in these that can’t be done with the native ones. All that wasted dev time is on you guys.
- Last week a guy held a session about all the memory leaks he found in these custom libraries/controls. Again, your teams don’t know the basic fundamentals of the language or programming in general really. Not sure how that’s apples fault.
- Your “great emphasis on unit testing” has gotten us 21% coverage on iOS and an Android team recently said to us “yeah looks like the tests won’t compile. Well we haven’t touched them in like a year. Just ignore them”. Stability of the app is definitely on you and the team.
- Having half the app in react-native and half in native (split between objective-c and swift) is making nobodies life easier.
- The company forces us to use a custom built CI/CD solution that regularly runs out of memory, reports false negatives and has no specific mobile features built in. Did apple force this on us too?
- Shut the fuck up6 -
THIS is why unit testing is important, I often see newbs scour at the idea of debugging or testing:
My high school cs project, i made a 2d game in c++. A generic top down tank game. Being my FIRST project and knowing nothing about debugging or testing and just straight up kept at it for 3 months. Used everything c++ and OOP had to offer, thinking "It works now, sure will work later"
Fast forward evaluation day i had over 5k lines of code here, and not a day of testing; ALL the bugs thought to themselves- "YOU KNOW WHAT LETS GUT THIS KID "
Now I did see some minor infractions several times but nothing too serious to make me refactor my code. But here goes
I started my game on a different system, with a low end processor about 1/4 the power of mine( fair assumption). The game crashed in loading screen. Okay lets do that again. Finally starts and tanks are going off screen, dead tanks are not being de-spawned and ended up crashing game again. Wow okay again! Backround image didn't load, can only see black background. Again! Crashed when i used a special ability. Went on for some time and i gave up.
Prof saw the pain, he'd probably seen dis shit a million times, saw all the hard work and i got a good grade anyways. But god that was embarrassing, entire class saw that and I cringe at the thought of it.
I never looked at testing the same way again.

Worst bad practice..
Manager: I need code today
Developer (thinking) : let me give it without unit test. Anyways tester will test it.
Manager to tester: complete testing fast.
Tester(thinking): developer must have unit tested it. Let me skip it.
Enjoy testing completed.
God help clients.. 😊5 -

Me: unit test, for yesterday’s task
SM: hm? Weren’t the QAs tested it yesterday
Me: yes, but it’s “unit test”
SM: so? Can’t you test it yourself?
Me: I can, but it’s UNIT TEST
SM: yeah I heard you the first time, the component is working right? Or is there any other point this testing for?
Me: *it seems this idiot doesn’t know what I’m talking about, blah blahblah blah (explaining what unit test is)

As a Java developer, reasons to kill other programmers:
- static mutable variables
- WRITING to static mutable variables
- API call with Framework X didn't work. Add Framework Y along with X and try that. Wrap X in try/catch statement. Catch block fires framework Y.
- six, seven, ten levels of nested code. Zero thought put in organization
- 6K LOC Java files
- spring (singleton? Maybe) object assigning values in static mutable (see pt.1)
- a couple of unit tests in code base that no longer work. Zero unit tests in new code
- unit testing disabled in CI pipeline
- empty catch blocks
- pass mutable data between threads. Modify in various places concurrently.3 -
No boss... For the fucking millionth time: unit tests are not a waste of time.
You keep testing everything manually and hoping that you tested everything every time and praying that there are no bugs IS THE FUCKING TIME WASTE
My boss just can't fucking wrap his head around automated tests... I'm trying hard... Gonna try harder...6 -

My friend and boss，told me he would teach me code 2 years in a half ago.
I didnt know what css or html was and i used to call java javascript.
I can know create my own module with webpack， have my automated doc， use react， redux， he taught me linux， git，unit testing， databases，docker， and so on...
Im not an expert in any of it butbi know what they are for and can play with them more or less comfortably.
The best advice he ever gave me was:
“coding is not about coding. We are like the greath painters of history. They were great at painting but even more at creating. If you have no creativity， you can paint as well as you want， its worthless.”2 -
I joined a "multi-national" company in middle-east where 90% of the developers are Indian. And since it's a "multi-national" company with 50+ developers I thought they already figured it out. Most of them have 5-10 years of experience. They should know at least how to use git properly, deployment should be done via CI/CD. database changes should be run via migration script. Agile methodology, Code Review - Pull Request. Unit testing. Design Patterns, Clean Code Principle. etc etc
I thought I'm gonna learn new things here. I have never been so wrong in all my life...
Technical Manager doesn't even know what Pull Request is. They started developing the software 4 years ago but used Yii v1 instead which was released almost a decade ago. They combined it with a VueJS where in some files contains around 4000 lines of code. Some PHP functions contain 500+ of code. No proper indentions as well. The web console is bloody red with javascript errors. In short, it's the worst code I've seen so far.
No wonder why they keep receiving complaints from their 30+ clients.11 -
User: “I’ve tried hundreds of different names. How come all the usernames are registered?!😤”

Today I'm going to work on my side project that I haven't touched in weeks.
I want to utilize Angular 2 which means I'll need to learn TypeScript. I also want to use the new .Net Core and EF Core 1.0. Oh and I want to handle authentication using JWT!
Wow, that's gonna be a lot of effort to get things off the ground... maybe instead I'll use this time to learn some new concepts. Maybe watch this episode of Fun Fun Function, or maybe this video on writing Assembly code for an app on Raspberry Pi, that sounds cool!
Actually, you know I should really teach myself dependency injection and unit testing for once. I'm so behind the times.
Well, really I should finish this book on design patterns first. Ok, where did I leave off? Page 20 I think... ehh... maybe I'll just work on my side project.
Tomorrow... tomorrow, I'll work on my side project.9 -
Old boss story. This guy was nice but a terrible boss. Also relevant, he has a background in IT so should know better.
Him: So when you wanna check a password is correct you just unhash it in the database?
Me: *facepalm*
Me: Hey we should be doing unit and integration testing at a minimum to lower bugs.
Him: We don't need those, we're not a bank. If a problem comes up we just fix it and push to production.
(A while later)
Him(in email): Why do we keep getting bugs reported. Don't you devs test your code.
I was mildly annoyed at that one.
Him: We're always over budget on projects, how can we fix this.
Me: What if we increase our quotes.(technically there are other ways as well but not really possible at that time)
Him: We can't do that, clients won't want to pay.
Me: *finishing off my handover as I'm leaving for a new job*
Him: Wow you do a lot of work2 -

Dynamically typed languages are barbaric to me.
It's pretty much universally understood that programmers program with types in mind (if you have a method that takes a name, it's a string. You don't want a name that's an integer).
Even it you don't like the verbosity of type annotations, that's fine. It adds maybe seconds of time to type, which is neglible in my opinion, but it's a discussion to be had.
If that's the case, use Crystal. It's statically typed, and no type annotations are required (it looks nearly identical to Ruby).
So many errors are fixed by static typing and compilers. I know a person who migrated most of the Python std library to Haskell and found typing errors in it. *In their standard library*. If the developers of Python can't be trusted to avoid simple typing errors with all their unit tests, how can anyone?
Plus, even if unit testing universally guarded against typing errors, why would you prefer that? It takes far less time to add a type annotation (and even less time to write nothing in Crystal), and you get the benefit of knowing types at compile time.
I've had some super weird type experiences in Ruby. You can mock out the return of the type check to be what you want. I've been unit testing in Ruby before, tried mocking a method on a type, didn't work as I expected. Checked the type, it lines up.
Turns out, nested away in some obscure place was a factory that was generating types and masking them as different types because we figured "since it responds to all the same methods, it's practically the same type right?", but not in the unit test. Took 45 minutes on my time when it could've taken ~0 seconds in a statically typed language.14 -
1. Slack. Pretty good chat app for dev companies, I use it to prevent people standing next to my desk 40 times a day.
2. Unit testing tools, especially when fully automated using a git master branch hook, something like codeship/jenkins, and a deployment service.
3. Jetbrains IDEs. I love Vim, but Jetbrains makes theming, autocompleting & code style checks with mixed templating languages a breeze.
4. Urxvt terminal. It's a bit of work at the start, but so extremely fast and customizable.
5. Cinnamon or i3. Not really dev tools, but both make it easy to organize many windows.
6. A smart production bug logger. I tend to use Bugsnag, Rollbar or Sentry.
7. A good coffee machine. Preferably some high pressure espresso maker which costs more than the CEO's car, using organic fairtrade hipster beans with a picture of a laughing south american farmer. And don't you dare fuck it up with sugar.
8. Some high quality bars of chocolate. Not to consume yourself, but to offer to coworkers while they wait for you to fix a broken deploy. The importance of office politics is not to be underestimated.1 -
Well now, I wouldn't want to mention anyone specific since talking about someone behind their back and calling them 'weird' isn't very nice. 🙄 But absolutely HYPOTHETICALLY speaking, if I HAD a weird coworker, they would probably...
- ... strut about the office, telling all how great yet underpaid their work is
- ... write lots of 'concepts' because coding is for lowly programmers
- ... insist that the code they have to do when boss is looking is simply too complicated for unit testing, and 'that's great!'
- ... brag about their/wear to work a ridiculous array of ties in every colour imaginable, when everyone else shows up casual
- ... trap people into listening to them talk for hours about...
-- ... ties
-- ... their misspent youth
-- ... how awesome they are/were/will be
-- ... why it's a good idea to eat cheese
- ... never let me forget I'm female, coz *insert BS reasons why all devs must by nature be male here*
- ... send me little unsolicited notes and mails with funny (sexist) jokes *har har*
- ... be let go, at which point everyone else discovers why they had so much time that they could spend chatting away at the watering hole
- ... earn the eternal hatred of anyone picking up the pieces of their 'work'
- ... try to steal our customers away who will laugh in their bloody face
Just my theory, of course..3 -
"We don't have time for writing tests"
"Yeah we could write them but only if the client paid us for that"
"You can just test new features manually!"

Dear god help me.5 -
After 10 years of development, and 7 years of being happily married, I'm in love again... With Unit Testing.

The weird feeling you get when you ask a colleague what he recommends as unit testing framework for C# and his first response is: "What do you mean by 'unit testing'?"11

Skipping unit tests and documentation ...
I'm starting to recover after not writing a single test for the first 6 years of my professional carrer (wasn't taught in school, didn't know where to start, man I should have really found a mentor earlier), and barely any documentation (I was the sole developer for several years, and just didn't get into the habbit).
Unit testing is still not a habit, but now I have the first tests to serve as an example and an idea what/how to test at least, and I try to get every new "framework" function/class at least commented properly.
Wish me luck2 -
"I'm almost done, I'll just need to add tests!"
Booom! You did it, that was a nuke going off in my head.
No, you shouldn't just need to add tests. The tests should have been written from the get go! You most likely won't cover all the cases. You won't know if adding the tests will break your feature, as you had none, as you refactor your untested mess in order to make your code testable.
When reading your mess of a test case and the painful mocking process you went through, I silently cry out into the void: "Why oh why!? All of this suffering could have been avoided!"
Since most of the time, your mocking pain boils down to not understanding what your "unit" in your "unit test" should be.
So let it be said:
- If you want to build a parser for an XML file, then just write a function / class whose *only* purpose is: parse the XML file, return a value object. That's it. Nothing more, nothing less.
- If you want to build a parser for an XML file, it MUST NOT: download a zip, extract that zip, merge all those files to one big file, parse that big file, talk to some other random APIs as a side-effect, and then return a value object.
Because then you suddenly have to mock away a http service and deal with zip files in your test cases.
The http util of your programming language will most likely work. Your unzip library will most likely work. So just assume it working. There are valid use cases where you want to make sure you acutally send a request and get a response, yet I am talking unit test here only.
In the scope of a class, keep the public methods to a reasonable minimum. As for each public method you shall at least create one test case. If you ever have the feeling "I want to test that private method" replace that statement in your head with: "I should extract that functionality to a new class where that method public. I then can create a unit test case a for that." That new service then becomes a dependency in your current service. Problem solved.
Also, mocking away dependencies should a simple process. If your mocking process fills half the screen, your test setup is overly complicated and your class is doing too much.
That's why I currently dig functional programming so much. When you build pure functions without side effects, unit tests are easy to write. Yet you can apply pure functions to OOP as well (to a degree). Embrace immutability.
Sidenote:
It's really not helpful that a lot of developers don't understand the difference between unit, functional acceptance, integration testing. Then they wonder why they can't test something easily, write overly complex test cases, until someone points out to them: No, in the scope of unit tests, we don't need to test our persistance layer. We just assume that it works. We should only test our businsess logic. You know: "Assuming that I get that response from the database, I expect that to happen." You don't need a test db, make a real query against that, in order to test that. (That still is a valid thing to do. Yet not in the scope of unit tests.)9 -
Today I started work on a new project that contains a lot of legacy. I asked the developers about unit testing javascript and was told that not only is there none in place, but it's not worth adding any in.
At first, I grimaced and thought fair enough. This is their codebase, it's their choice. I've now been thinking about this for a few hours and have instead decided that screw those guys, I'm adding in a testing framework, a module pattern that's compatible with the existing code, and unit testing the crap out of it. If they don't want it they can refactoring it out, but I can't bring myself to intentionally deliver code I know is crap.
I WILL FORCE CODE QUALITY ON THEM.7 -
Ignorant, stale old Dev I work with discovers huge bugs with a new project. A few weeks earlier I had brought up the fact that he does zero unit and behaviour testing and got basically laughed at.......
-
Just joined a new team at the organisation as senior dev.
Team lead keeps singing about how we need unit testing and good standards.
I implement domain pattern on the backend supported by unit tests.
It passes QA and then get an earful about the code not being 'restful'. What does that even mean?
Well, it matters not since team lead changes the whole feature in the release branch and all unit tests obviously fails. Builds start to fail.
The solution? Comment out all unit tests. In the sprint retro, we hear the same old adage 'we need 80% code coverage'
Do as i say, not as I do. FML.6 -
After working 3 years in my current job and my boss hating anything to do with unit testing etc, I used my spare time to refactor our Makefiles to allow for the creation of unit and integration tests. I technically didn't tell my boss about it, so my heart was in my throat when he Skyped me with 'what did you change in ...'?
After having bashed any workflow with testing in it, I showed him the new workflow and automatic testing in Jenkins and he was actually enthousiastic, just like all other employees! I was hailed a hero in the R&D department, after all this time we can finally write universal tests. :D9 -
Greatest dev sin.... oh god there’s been a few over the years.
Hmm 🤔
I guess one of the top 5 would be making an ecommerce platform without unit testing or documentation for the front or backend. 🤫
Mind you it runs smoothly to this day so I was doing something right 😦1 -
Today I had to write a unit test to test a method that internally used a random number generator...
Aha
Ahaha
Ahahaha
My test was literally just assertNotNull...4 -
Some ranters get pissed with junior dev who thinks unit testing is not necessary and a waste of time. While I'm here convincing all senior devs in my office why testing is important. I gave up.3
-
Found out today that the company wants to hire the consultant that thinks that unit testing is a waste of time, CI and code coverage metrics are useless, DI is mumbo-jumbo. But 500+ line procedural methods are fine, you just start the method with a small essay of a comment on what it does...6

I don't get it why there are so many people out, that think testing stupid model classes with getters and setter is needed.
Dude. There is no logic in this class ... it's pure data that gets not modified there (well except if you call the setter)
I've wasted way too much time writting useless unit test because some ppl want to masturbate on 100% code coverage 🤦🏻♂️13 -
Question time:
Has anyone used PHP unit with Selenium before?
I have a.. well words can’t explain it nice enough but, beyond a joke, not even funny, spaghetti code base I’ve come to inherit recently, which god help me, doesn’t follow any design patterns at all, it’s just a stamp this here, staple this down over here and throw paint at the wall and hope it sticks.
It’s a mixture of procedural and functional with the rare class kind of mess.
So attempting to refactor by any means is not a real possibility without some kind of behavioural testing in place first otherwise I know I’m going to end up breaking something somewhere and not even know it.
Also if anyone has had the privilege of such code bases, tips to dealing with the mess are appreciated.
Oh and no, I can’t rm -rf or start again.😭5 -
God: you qualify for reincarnation. What advice from past life do you want me to retain in your memory ?
Me: never forget to write those unit tests!2 -
git push origin stupid-long-feature-name
git pull origin develop
*Checks through all changes. No major conflicts. Accepts changes.*
npm test
*4 failing tests, none of them in pieces that I touched for my feature.*
*That's funny. QA was loaded from the develop branch, and everything works.*
*Actual data has dates from today. Expected data has dates from a week ago.*
*examines tests*
Why are all these expected dates hard-coded‽
tl;dr The external development team committed 4 tests that would only ever pass on the day they were written.5 -
The fucker complains when someone doesn't write unit tests, meanwhile he tops any new code he writes with a @codeCoverageIgnore annotation ... 😒😒7

Dear coworker,
when I asked: "So, how does it work?", I didn't expect the answer to be: "Well, you push this button, wait three seconds and when it's finished, this LED turns on."
I was hoping for a more in-depth description (like, the way you'd consider me to be seriously interested in your work or learning from you) along the lines of "Well, you see, I have written this CLI-Tool here, which connects to the adapter and parses the contents of the file via serial interface to the on-board controller. This controller performs an integrity check of the device and then decides whether to flash or not. The testing unit itself checks if its being programmed with the right parameters."
Of course I know how a programming device works but I was interested in your solution in this special case ... so I think I'll just check the doc later if there'll ever be some.4 -
Not sure if it was 2016 or late 2015, but it's a fun story anyway (and if it's not you'll at least learn something from it).
Back at the time I was quite new to unit testing (weird how it has become second nature in a years time). I was writing some software that was supposed to send out some SMS to customers. Of course this had to be tested. However, it was a bit difficult to test (or so I thought) without actually receiving an SMS to know if it was sent. So I decided to use the live API key to make sure the sending of SMS was actually working correctly. I tried it a few times but didn't receive an SMS. So I kept working on it and running tests.
The testing setup I had at the time was just a continues loop that went through all tests to make sure it all still worked (I've moved to only checking on file changes now, but that is besides the point). Keep in mind I was still running these tests, in a loop, with the _live_ API key.
So the end of the working day arrives and I go home and sit in the train. All of the sudden I receive some test SMS. I was thinking "hey nice, it did work". Then I started receiving more. It soon turned out to be an alarmingly big amount of SMS. It stopped around 100, but don't think that was the end of it. Oh no. I had changed the number to send the SMS to from my own number to a different number (+31612345678 to be exact, which I found out later isn't an actual phone number. I really hope I was right about that). I was beginning to become nervous, but there wasn't much I could do.
The next day I returned to work and checked the API for sent SMS. Turns out I had sent a couple of thousand (I think between two and three thousand) SMS in a couple of hours. Most of them to the test number I had supplied.
This probably cost the company a couple of hundred euros. Luckily my colleagues and team leader all thought it was pretty funny, but did tell me not to do it again. And I haven't of course.
Lesson learned: don't use live API keys during testing (among other things :)).
So yeah that was probably my worst dev experience.1 -
Nobody Unit Tests.
So it's already 1:15am late night and I am all tucked up in bed watching Roy Oshrove talk on unit testing and ways to write correct unit test. My friend walk in and finds me in bed watching this. He seems surprised as what are you doing ??
I replied it is an interesting talk on unit testing.
He says are you mad? Who the hell does unit testing ?
People out there are spitting on unit test code base. And they don't write unit tests.
Nobody unit tests.!!
I stay calm. I know there is no point of arguing. I said I'll sleep in some time.
And he works as developer, a job that I applied an never got because of connections.
I am optimistic someday I'll find a job that I deserve. The developer world is in danger. !!!7 -
I was asked to fix a critical issue which had high visibility among the higher ups and were blocking QA from testing.
My dev lead (who was more like a dev manager) was having one of his insecure moments of “I need to get credit for helping fix this”, probably because he steals the oxygen from those who actually deserve to be alive and he knows he should be fired, slowly...over a BBQ.
For the next few days, I was bombarded with requests for status updates. Idea after idea of what I could do to fix the issue was hurled at me when all I needed was time to make the fix.
Dev Lead: “Dev X says he knows what the problem is and it’s a simple code fix and should be quick.” (Dev X is in the room as well)
Me: “Tell me, have you actually looked into the issue? Then you know that there are several race conditions causing this issue and the error only manifests itself during a Jenkins build and not locally. In order to know if you’ve fixed it, you have to run the Jenkins job each time which is a lengthy process.”
Dev X: “I don’t know how to access Jenkins.”
And so it continued. Just so you know, I’ve worked at controlling my anger over the years, usually triggered by asinine comments and decisions. I trained for many years with Buddhist monks atop remote mountain ranges, meditated for days under waterfalls, contemplated life in solitude as I crossed the desert, and spent many phone calls talking to Microsoft enterprise support while smiling.
But the next day, I lost my shit.
I had been working out quite a bit too so I could have probably flipped around ten large tables before I got tired. And I’m talking long tables you’d need two people to move.
For context, unresolved comments in our pull request process block the ability to merge. My code was ready and I had two other devs review and approve my code already, but my dev lead, who has never seen the code base, gave up trying to learn how to build the app, and hasn’t coded in years, decided to comment on my pull request that upper management has been waiting on and that he himself has been hounding me about.
Two stood out to me. I read them slowly.
“I think you should name this unit test better” (That unit test existed before my PR)
“This function was deleted and moved to this other file, just so people know”
A devil greeted me when I entered hell. He was quite understanding. It turns out he was also a dev.3 -
"Coding se darr nahi lagta Sahab, Unit Tests likhne se lagta"

As a fresher, UTs scare me.5 -
I'm finally writing unit tests consistently thanks to a simple file organization decision.
I'm not doing pure TDD, but at least I'm writing the tests immediately after writing a module, and I make sure they run ok.
What I'm doing is Instead of putting the test files in a "tests" dir at the root of the project, I have the tests right next to the source code.
So if I have a dog.x file, I also have a dog.test.x file next to it.
I'm not inventing gunpowder here. I've seen several people do this.
But it's something that is not generally made a default or advised to do.
Like I said; test frameworks in general go with the classic "tests" dir.
But for me this is day and night in whether I write the tests or not.
Which makes sense. Imagine the classic scenario of the "tests" dir, and you just created a file deep into a hierarchy, let's say src/lib/console/windows/dog.x
This means that if you want to write tests for that, you need to make sure the hierarchy tests/lib/console/windows/dog.test.x exists
If the test file already exists, but you want to access both files, you need to traverse deep for each.
Also, it's actually harder to keep track which files have unit tests and which do not.
Meanwhile, if the test files are next to the source, all these problems disappear.
That doesn't mean there are no other challenges with testing, like testing untestable things, like system calls or http requests, but there are ways to deal with that. -
Apart from having a baby which is the hardest in the world，i think the hardest project is to learn to code.
I studied philosophy and anthropology but gamed a lot. Me and a good mate decided to work together and he told me hed teach me coding.
The guy is a genius but he is a reckless rebel genius who tells everybody to fuck off.
So，after 1 year in a half of intense coding where i had to learn linux， networks， and im not shitting you html and css as well and of course javascript.
He has now put me on， for the last 2 month， in charge of our front end backoffice. I have to design forms that do the right http requests，do the unit testing， play with redux-form， react-redux and he has thrown me into the basic java backend so i can begin working with entites and how i serve the data and link it to the database and even create tables.
Every time i fail hemakes me remake everything.
I actually came on devrant to study the dev community (i always gamed a lot but this is a whole different community). The dev community is pretty awesome and unique.
Anyhow， i remember when i saw him as me to complete an exercise and i didnt event know which words were the reserved language ones and those i could use myself. It was like fucking magic.3 -
Fucking first rant here:
So we tried to teach Two new colleagues to typescript and git and testing and stuff and we have a SPOC “which claimed to be very technical”. The SPOC’s task is to keep an eye on the work, and today we have had a review...
After two weeks, the created multiple branches into our git, all with one commit of 400 LOC changed, no merge requestet, issue in Redmine set to “closed”.
Well, by the way they were supposed to write Unit tests for our app.
But I thought, ok, we’ll check their branches.
Their tests all passed (cz) but man, the app didn’t and on compilation there were errors, the app is broken. Damn.
Is it really so far off, that even of They wrote tests, that the app should still work?
AND I THOUGHT IT IS COMMON SENSE. Damn!
Guess how needs to fix it6 -
When your product owner tells you to forget about architecture and unit testing, "just push it out"...
2 -
The "unit" in unit test does not mean your ENTIRE APPLICATION. Ever heard of scope!?
I am amazed how often people write overblown test setups, mock hundreds of unrelated services, just to test one tiny bit of logic.
That bit of logic could have been a pure function.
For that pure function you could write a dead simple unit test. Given that input, I expect that output. Nothing more, nothing less. (It helps even more if the pure functions only accepts primitives, like string and numbers, or very simple immutable value objects).
No I don't care that the service is used by another service, as your mocked interaction also doesn't test the service as a whole but you just assume the happy case most of the time anyway. You want to test the entire application? Let's not use unit tests for that but let's use a different kind of test for that (integration test, functional tests, e2e-tests).
If you write code in a way that easily allows for unit testing, your need to mock goes away.1 -
Unit testing is cool and all, but FFS...
If you want unit test - cool. But its not drop-in replacement for functional testing!
I believe each release should be manually tested.9 -
We have a production release tomorrow and we didn't have any kind of testing other than the unit tests we wrote. 💣💥🤯🎆3

I've been an iOS developer for a number of years now. I like learning new technologies and approaches, but recently I've been getting more and more frustrated by how complex and fast paced everything is becoming.
It used to be that you had to know Objective-C and UIKit and you were set. Then things like unit and ui testing became popular. Swift came out with its set of fancy features and different way of seeing things. Everyone wants to use some sort of architecture. The number of frameworks released just by Apple is mind boggling and getting any sort of exposure to most of them works be a full fine work. Then there is the whole third party ecosystem. There are so many tools and frameworks for everything (which are popular) that I can't even keep up with the new names I keep coming across.
Sure, I can learn new things, I like doing it. However, recently i I've applied to a company and they wanted knowledge of RxSwift. Well, experience, possibly writing a full blown app from beginning to the end. And it had to be highest possible quality, not a kind of "look, I know RxSwift, I can write apps in it, I'll learn more as I go along".
Other place wanted experience in the continuous integration system and ui testing framework that they use. And they expected to to know a lot about one of the many architecture you can use.
Then there is a lot of places that want you to know React Native. Sure, JavaScript is not complicated and the framework simplifies development, but getting to know the tools, creating a toy app, going through a lot of mistakes takes a lot of time. And of course you have to have demonstrable experience in it. Best if you've released an app written in it.
Then you're expected to be involved in the community. Side projects, open source projects. I've been getting the impression that it's becoming more and more about building your personal brand.
In short, I've been getting tired of all of that. It's exciting, but the expectations I find overwhelming. If I start learning a third new thing, I'm going to forget the first one. I miss the simplicity and the clarity of the early days of mobile development.4 -
Need to rant. I am doing programming 2 at university with java and the assessment is to make a card game. The subject is shit and is basically going over loops, variables, conditionals ect which we learned in introduction to programming and programming 1.
This leaves little time for oop principles, design patterns inherentance and all other useful stuff.
I am dedicated to making a career in programming and want to do my assessment the correct oop way. Although the lecturer doesn't care and is instructing the class to do it procedurally and shit.
I could do the program really quickly the shit procedural way and still get full marks but I feel dirty as hell coding like a scrub. So I'm 60 hours in on this assessment and there are so many classes and even more because of unit testing (we don't have to unit test) and I am spending way too much time.
My code is beautiful, my classes are tiny and maintainable, easy to modify and I'm learning so much about how to code oop the correct way with the help of a mentor and someone I look up to. But god does it take forever to code this way. And soo many iterations and redesigns because I'm still learning.
It's almost done but now I have another programming assessment for another class I'll have to do the dirty way because of time restraints and other assessments.
Sorry for wall of text but this is stressing me out 😛4 -
There is always that one guy.. who doesn't give a fuck about testing and thinks he's not responsible for them...
Le Guy: lemme just push ma new code maan
Jenkins: Unit Tests failed - pls fix
Le Guy to the one who cares about testing: hey fuck uu, ur stupid tests are failing... fix them its ur problem.
*sigh*7 -
*Completes unit testing training*
*Achieves fresh perspective*
*Looks at game code*
*Prepares to right unit tests for that problem method*
*Stares at code as crickets chirp*4 -
Not learning unit testing... I've heard so many good things about them, but I've never learned how to inple.e t and use them.
Maybe I can start now, can anyone point me in the write direction?5 -
My new favourite commit message:
"All changes as of 18th Sept"
How tremendously useful? There I was looking to know what changes were made to enable a feature / service, thought I could look for that in the commit message, but no you've given me a much more efficient way of finding out.
I simply need to download the contents of your memory, find out what date you made a change, and then dig through the massive commit to find the piece of info I need.
Forget experience using Git features, managing merges, following Git flow, or even any other SCM ... how can people be so tick when it comes to recording what they've done.
Heres a little cheat sheet for those struggling:
- Commit message
Describe what you actually ****ing did. Don't tell me the date or the time, thankfully Git records those. Don't tell me the day of the week, if I need to know I can figure that out, just tell me what ... you ... did.
- Feature branch names
Now this is a tricky one. You might be surprised to know that this isn't in fact suppose to be whatever random adjective or noun popped into your head ... I know, I too was shocked. The purpose of this is to let other people know what new feature is being worked on in this branch.
- Reusing feature branches
Now I know you started it to add some unit tests, and naming it "testing" is sort of ok. But its actually not ok to name it testing when you add 3 unit tests ... then rip out and replace 60% of the business logic. Perhaps it would have been wiser to create a new feature branch, given you are now working on a new feature.2 -
I started my actual gig as CTO of construction group (Innovation Hub) a year ago. And it was a hell of a ride, implementing kind of a scrum-ban for project management, XP, peer-reviews, a git-flow, git commit message formats, linters, unit testing, integration tests, etc...
And it's the fun part because with the CIO we had to drive the board to do A LOT of changes in their IT/Innovation drive.
But in one year there is a lot of KPI that went up :
* Deployment: When I arrived it took three stressful days to deploy a new version of one application, once a month. Today we do it every week, and it takes three annoying hours.
* We had no test. NOTHING! Today we have 85% code coverage for the unit test, and automatic integration tests run by our CI server every day.
* We had almost no documentation. Today our code is our documentation (it automatically extracted and versioned).
* We had 0 add value in the use of git. With commit messages as "dev", "asked task", inside jokes and a lot of "fix" and "changes". Today we have a useful git, and we even use it to create our deploy changelogs (and it's only mildly annoying!).
* More important, the team is happy! They get their purpose, see betterment in their tech mastery. They started doing conception, applicative architecture, presentations, having fun.
There is still a LOT of bad things we are still working on, and trying to solve (support workflow and betterment). But seeing what they already did, I'm so proud of my TEAM! I'm a fucking asshole, workaholic, "just do it" kind of guy. But they managed to achieve so much. Fucking PROUD!! -
Not really a rant but I always hated unit testing because I always had to write it for code that has been written ages ago. I started a personal testdriven project a couple of months ago and I now must admit, I kinda love unit testing. My code is way better, more readable, more stable and last but not least, i know when i broke something.3
-
It's a twisted feeling when your team decides to fix up their unit tests and not just mock everything. Yay, because it's now done correctly. "Are you fucking kidding me?!" when you realize that that means you now have to add tons of new instances of classes that the main one now needs, now that it's no longer mocked. 😑😐🙃2
-
Before i found out about unit tests i'd create a console application where i'd test the functions
Good times -
When you have to sit with a developer and walk them through coding a solution step by step, but they have more experience than you in your field. I had to show them how to unit test the thing they wrote properly as well, because they couldn't figure out you need to actually call the method you are unit testing in your test.3

I would describe the test project i inherited as a watermelon test suite,

First software refactoring in the company I worked for. No test environnement because "who needs it?", no unit testing, no comments, had to make sql updates and shit, was scared all day long that something would fuck up.
"Fuck fuck fuck, forgot a part of the where !" Had to fix everything quickly so no one would notice, no coffee/smoke pauses. On top of that, got a ton of retarded requests from the PM and other technicians working with me like "hey boi, could you add an icon to every button we made? There's like a thousand, we need it for tonight, our client will come visit us and I want to show him a better interface blablabla"
And since I was an intern, I couldn't refuse, had to work like a prostitute in virgin-land, and for what?
"Oi, you did good, now do other stuff"1 -
Once again, I have to go with the guy that, after seeing my horrible (I can't highlight this enough) code, decided that even I wasn't hopeless, and went on teaching me the basics of software engineering, top-down design and unit testing. All of this in two days, but it gave me the motivation to work on it, and look at me now: I'm a devRanter :')

Listened for about a half-hour yesterday to DevA ‘beat down’ DevB writing a console app for trying out a proof-of-concept idea he had.
DevB: “What’s the URL of the development server?”
DevA: “Why? What are you doing?”
DevB: “I’m needing to throw some messages to it so I can capture data for something I’m working on.”
DevA: “How are you calling the service?”
DevB: “I wrote a console app”
- you could almost hear the eye roll -
DevA: “A console app? Why in the world would you write a console app?”
DevB: “Oh..um..no reason. I just need log some test data for something I’m playing around with. How should I do it?”
DevA: “If it’s test data, you should have wrote a unit test. You see, unit tests …”
- yammer on and on for about 5 minutes about the virtues of unit tests…never really explaining anything -
DevB: “Yea, I’m not needing to test the result or anything. I just need to log some data.”
DevA: “Then you should use a unit test for that, not a console app. With a unit test, you’ll be able to validate the data. That’s what unit tests are for. Microsoft should have never put in console apps in Visual Studio. It just leads to bad coding practices.”
DevB: “Um…I don’t care. It’s a console app because I just need data…thanks anyway”
Today, DevC was talking to DevA
DevC: “Charlie is testing the order module, but there isn’t any test data. Do you still have the data generating script?”
DevA: “Oh yea, I’ll send him my console app that populates the database.”
It was all I could do from screaming “You stupid –bleep-er!! What the f–bleep-ck was all that yesterday?!”, but none of my business. Better to devrant about it than start a fight. -
Me: Spend lots of free time (evenings, weekends, sometimes even mornings) learning new languages, new architectures, new libraries. A lot of effort so I'm at the top of the current tech. Swift, Kotlin, MVVM, MVP, C++, functional programming, reactive programming, continuous integration, unit testing...
Get a new job - once again I have to clean up some shitty code, written by someone who went from Java script to objective c, without reading a single book on iOS development. Unused code, commented out code, redundant code, dead code. Unused assets that no one could be bothered to remove for the past 2 years.
Sometimes I wonder why do I even bother if all I ever do is maintain mess done with outdated tech by someone who couldn't give a 🐙🐙🐙 -
TIL how time-delay relays are used in circuits with a hell lot of power. For example to power and control the motor of a machine that lifts 20 people up to the sky and back to ground again.
FYI this is a simple circuit. We will hopefully start experimenting with SPS/Speicherprogrammierbare Steuerung (Programmable Logic Controllers). I cannot wait to make use of our predesigned circuits with complex logic gates with the new unit we will get to know.
Unfortunately, we will do practical networking (testing cables for the signal strength and speed, building a network of telephones and call each other - guess this is going to be the funniest part lol, etc.) before the SPS and LOGO software phase.
Btw. I am doing an all-nighter rn and repeating everything we did in our recent signal calculation lesson. We have another exam tomorrow.

"Manual testing is often quick and easy and satisfying – you can directly test your application, one can see the results immediately on your screen, and one can interact with the application “for real”, instead of in the sometimes-awkward scripted/mocked mode of unit tests. It’s a very natural instinct.
However, it’s also largely-wasted effort! A manual test only verifies the current state of the code base. As soon as you make a change, you’ve started to invalidate the results. If, however, you take the effort to encode the test in code as an automated test, it continues to be valid indefinitely into the future."

We rewrote the whole thing, except for iFraming some old pages in. We had to, the system was fucking awful and couldn't cope with any of the new mission critical requirements.
Client didn't understand the scope. Our project leader somehow snuck it in and we worked on it for months. We were sure we'd be kicked off the whole project... Somehow things didn't crash and burn. How it didn't blow up defies rational thought and the laws of physics. The new system worked, the client was happy, and boss made a lot of money.
Lead dev worked weekends for what feels like an eternity, it really was his baby and no one else on our company could have done it. It's where I finally learned how to do things the proper way; DDD, unit testing and TDD, architecture, building strong components in front-end, you name it. Before that I had a great nose for code smells and how not to do stuff, but now I got to see a proper system for the first time. It was glorious.
Then lead dev left and the system degraded quite a bit because new team didn't keep to the architectural patterns or general best practices. But we had a good run.1 -
So I decided today was a good day to manually compile python 3.6 for my raspberry pi as it hasn't yet been added to any supported repo's. Site says: this will take approximately 30 minutes.
3 hours later: "starting unit testing"2 -
There is how you think a system works, and there is how it actually works. Unit tests help keep those two ideas in sync with each other7

TLDR: fuck this plugin.
Longer version: I recently had to implement an external Vue plugin to upload files. That gave me a good headache already, mostly due to the half Chinese, half Google Translate English documentation. I now found out that testing the implemented component may be impossible. Turns out it overwrites the $route and $router variables and makes them read-only. Which won't even let me create a shallow mount of my implementation. Fuck this shit, I'm getting a drink!4 -
During one of our 'pop-up' meetings last week.
Ralph: "The test code the developers are checking in is a mess. They don't know what they are doing."
ex.
var foo = SomeLibrary.GetFoo();
Assert.IsNotNull(foo);
Fred: "Ha ha..someone should talk to HR about our hiring practices. These people are literally driving the company backwards."
Me: "I think unit testing is complete waste of time."
- You could almost see the truck hit the wall and splatter watermelon everwhere..took Ralph and Fred a couple of seconds to respond
Fred: "Uh..unit testing is industry best practice. There is scientific evidence that prove testing reduces bugs and increases code quality"
Ralph: "Over 90% of our deployments are rolled back because of bugs. Unit testing will eliminate that."
Me: "Sorry, I disagree."
- Stepping on kittens wouldn't have gotten a worse look from Fred and Ralph
Fred: 'Pretty sure if you ask any professional developer, they'll tell you unit testing and code coverage reduces bugs.'
Me: "I'm not asking anyone else, I'm asking you. Find one failed deployment, just one, over the past 6 months that unit testing or code coverage would have prevented."
- good 3 seconds of awkward silence.
Ralph: "Well, those rollbacks are all mostly due to server mis-configurations. That's not a fair comparison."
Me: "I'm using your words. Unit tests reduces bugs and lack of good tests is the direct reason why we have so many failed deployments"
Boss: "Yea, Ralph...you and Fred kinda said that."
Fred: "No...we need to write good tests. Not this mess."
Me: "Like I said, show me one test you've written that would have prevented a rollback. Just one."
Ralph: "So, what? We do nothing?"
Me: "No, we have to stop worshiping this made up 80% code coverage idol. If not, developers are going to keep writing useless test code just to meet some percent. If we wrote device drivers or frameworks for other developers maybe, but we write CRUD apps. We execute a stored procedure or call a service. This 80% rule doesn't fit for code we write."
Fred: "If the developers took their head out of their ass.."
Me: "Hey!..uh..no, they are doing exactly what they are being told. Meet the 80% requirement, even if doesn't make sense."
Ralph: "Nobody told them to write *that* code."
Boss: "My gosh, what have you and Fred been complaining about for the past hour?"
- Ralph looks at his monitor and brilliantly changes the subject
Ralph: "Oh my f-king god...Trump said something stupid again ..."
At that point I put my headphones on went back to what I was doing. I'm pretty sure Fred and Ralph spent the rest of the day messaging back-n-forth, making fun of me or some random code I wrote 3 years ago (lots of typing and giggling). How can highly educated grown men (one has a masters in CS) get so petty and insecure?7 -
Hmm. Seniors have the half working experience as I do and I am the only not senior one in Dev team.
I adapt code only to "taste" good for code reviewers, but they allow themselves to commit without caring and just saying :"oh unit testing is boring"
Enough with the kindergarten. Time to prepare myself for the next job.1 -
Me: Wrote and unit testing code for a user story.
Day of a Merge
PO: We need to back out the code you wrote. We have not gotten approval from legal.
Me: Uhhh well it's not going live for 4 weeks still and not harming anything but if you insist, ok.....
2 Days Later
PO: Ok legal approved the changes can you put that back in?
Me: 😡🖕🏻1 -
rant?
When you want to write the unit test that demonstrates a subtle bug, but before recreating the same preconditions you end up writing 15 other tests, testing a lot of other stuff too, that in turn show other bugs, and skyrocketing the coverage (that was sitting at 0% actually).
Like I wanted to repair a hole in my umbrella to not get wet, and built a house instead. -
Spent fucking 11 hrs on fixing a stupid bug in Laravel that caused all my unit tests to fail. Just because that unit testing method has no unit test...

Ok.. So I applied for a web dev position at a small-to-medium sized company. They had a telephonic round which they were happy with. They then sent out an assignment for me (A simple webapp to complete in 1hr). I did it and sent them the code. Finally, the face to face interview also went well.
At the end of it all, the HR comes back and tells me - "You did not use a MVC framework for the assignment and your code was not optimized for unit testing."
Me - "Ugh. (1) You did not have to call me for the face to face interview if you did not like my code. (2) You specified NOT to use any 3rd party libraries when doing the assignment. (3) You can tell people directly that you cannot afford them."4 -
"I don't think we should be playing with our privates {variables} like that" - framework designer
= context =
It was noticed that we have too many setter functions to change private variables just to do unit tests. So we had a small meeting to discuss what to do about this.
Options:
- don't do the test
- ignore till another time (ie: keep the functions till its a problem)
- put the variables into a provider
- use reflection (the above quote was a reaction to this option)6 -
FUCK YOU GOOGLE
I feel I have zero control as a developer.. You made the shittiest choice by bringing in intellij , you made an even worse choice by adding gradle.. You add thousands of configuration options to manifests, layouts but provide no common place to find documentation for them.. This is just nonsense.. I've wasted endless hours figuring out your dex limits, proguard rules.. It's just frustrating.. Could you be anymore counterintuitive with your unit testing framework! Honestly it's a steaming pile of shit..5 -
#noestimates
I fucking hate doing estimates. It stresses me out. I just did it, for a requirement about migration. I'm on my way to a fight now with the PO, because "the estimated time is too long". There was an agreement that deliverables were not to have extensive documentation and unit testing will only cover 30% of each use case (I know, stfu), but that's gone so I have to do the whole thing. I estimated 160 hours coding time, 40% of that for docs and 50 for testing. I'm standing by it.
All that stuff aside, what bothers me the most about estimates is that there's lazy motherfuckers who say shit like "I can have their RESTful ws in 2 days, but I said a month, because fuck it" and generate a win-win situation for them and their company, because the client - practically everytime - will just argue for the task to be completed in barely 10% less of the estimated time, accept the proposal and be happy waiting, the developer will fucking dawdle and the company will be paid for more hours than it deserves. Ugh.
Fuck estimates.2 -
Tabs, or No Tabs? I did the same as this commentor 2 years ago. I can code so quick now because of this simple switch. Here's why:
(source, Laracasts.com)
Ben Smith
"I think the most beneficial tip was to do away with tabs. Although it took a while to get used to and on many occasions in the first few days I almost switched them back on, it has done wonders for my workflow.
I find it keeps my brain more engaged with the task at hand due to keeping the editor (and my mind) clutter free. Before when I had to refer to a class, I would have opened it in a new tab and then I might have left it open to make it easier to get to again. This would quickly result in a bar full of tabs and navigation around the editor would become slow and my brain would get bogged down keeping track of what was open and which tab it was in. With the removal of the tab bar I'm now able to keep only the key information in my mind and with the ability to quickly switch between recently opened files, I find I haven't lost any of the speed which I initially thought I might.
In fact this is something I have noticed in all areas of writing code, the more proficient I have become with an editor the better the code I have been writing. Any time spent actually writing your code is time in which your brain is disconnected from the problem you are trying to solve. The quicker you are able to implement your ideas in code, the smaller the disconnect becomes. For example, I have recently been learning how to do unit testing and to do so I have been rewriting an old project with tests included. The ability to so quickly refactor has meant that whereas before I might have taken 30 seconds shuffling code around, now I can spend maybe 5 seconds allowing my mind to focus much better on how best to refactor, not on the actual process of doing so."
jeff_way Mod
"Yeah - it takes a little while to get used to the idea of having no tabs. But, I wouldn't go back at this point. It's all about forcing yourself into a faster workflow. If you keep the tabs and the sidebar open, you won't use the keyboard."2 -

Nice to do some refactoring of the whole data access layer of our core logistics software, let me tell an story.
The project is around 80k lines of code, with a lot of integrations with an ERP system and an sql database.
The ERP system is old, shitty api for it also, only static methods through an wrapper to an c++ library
imagine an order table.
To access an order, you would first need to open the database by calling Api.Open(...file paths) (yes, it's an fucking flat file type database)
Now the database is open, now you would open the orders table with method Api.Table(int tableId) and in return you would get an integer value, the pointer.
Now for the actual order. first you need to search for it by setting the search parameter to the column ID of the order number while checking all calls for some BS error code
Api.SetInt(int pointer, int column, int query Value)
Then call the find method.
Api.Find(int pointer)
Then to top this shitcake of an api of: if it doesn't find your shit it will use the "close enough" method of search.
And now to read a singe string 😑
First you will look in the outdated and incorrect documentation given to you from the devil himself and look for the column ID to find the length of the column.
Then you create a string variable with ALL FUCKING SPACES.
Now you call the Api.GetStr(int pointer, int column, ref string emptyString, int length)
Now you have passed your poor string to the api's demon orgy by reference.
Then some more BS error code checking.
Now you have read an string value 😀
Now keep in mind to repeat these steps for all 300+ columns in the order table.
News from the creators: SQL server? yes, sql is good so everything will be better?
Now imagine the poor developers that got tasked to convert this shitcake to use a MS SQL server, that they did.
Now I can honestly say that I found the best SQL server benchmark tool. This sucker creams out just above ~105K sql statements per second on peak and ~15K per second for 1.5 second to read an order. 1.5 second to read less than 4 fucking kilobytes!
Right at that moment I released that our software would grind to an fucking halt before even thinking about starting it. And that me & myself and I would be tasked to fix it.
4 months later and two weeks until functional beta, here I am. We created our own api with the SQL server 😀
And the outcome of all this...
Fixes bugs older than a year, Forces rewriting part of code base. Forces removal of dirty fixes. allows proper unit and integration testing and even database testing with snapshot feature.
The whole ERP system could be replaced with ~10 lines of code (provided same relational structure) on the application while adding it to our own API library.
Best part is probably the performance improvements 😀. Up to 4500 times faster and 60 times less memory usage also with only managed memory.3 -
I need some opinions on Rx and MVVM. Its being done in iOS, but I think its fairly general programming question.
The small team I joined is using Rx (I've never used it before) and I'm trying to learn and catch up to them. Looking at the code, I think there are thousands of lines of over-engineered code that could be done so much simpler. From a non Rx point of view, I think we are following some bad practises, from an Rx point of view the guys are saying this is what Rx needs to be. I'm trying to discuss this with them, but they are shooting me down saying I just don't know enough about Rx. Maybe thats true, maybe I just don't get it, but they aren't exactly explaining it, just telling me i'm wrong and they are right. I need another set of eyes on this to see if it is just me.
One of the main points is that there are many places where network errors shouldn't complete the observable (i.e. can't call onError), I understand this concept. I read a response from the RxSwift maintainers that said the way to handle this was to wrap your response type in a class with a generic type (e.g. Result<T>) that contained a property to denote a success or error and maybe an error message. This way errors (such as incorrect password) won't cause it to complete, everything goes through onNext and users can retry / go again, makes sense.
The guys are saying that this breaks Rx principals and MVVM. Instead we need separate observables for every type of response. So we have viewModels that contain:
- isSuccessObservable
- isErrorObservable
- isLoadingObservable
- isRefreshingObservable
- etc. (some have close to 10 different observables)
To me this is overkill to have so many streams all frequently only ever delivering 1 or none messages. I would have aimed for 1 observable, that returns an object holding properties for each of these things, and sending several messages. Is that not what streams are suppose to do? Then the local code can use filters as part of the subscriptions. The major benefit of having 1 is that it becomes easier to make it generic and abstract away, which brings us to point 2.
Currently, due to each viewModel having different numbers of observables and methods of different names (but effectively doing the same thing) the guys create a new custom protocol (equivalent of a java interface) for each viewModel with its N observables. The viewModel creates local variables of PublishSubject, BehavorSubject, Driver etc. Then it implements the procotol / interface and casts all the local's back as observables. e.g.
protocol CarViewModelType {
isSuccessObservable: Observable<Car>
isErrorObservable: Observable<String>
isLoadingObservable: Observable<Void>
}
class CarViewModel {
isSuccessSubject: PublishSubject<Car>
isErrorSubject: PublishSubject<String>
isLoadingSubject: PublishSubject<Void>
// other stuff
}
extension CarViewModel: CarViewModelType {
isSuccessObservable {
return isSuccessSubject.asObservable()
}
isErrorObservable {
return isSuccessSubject.asObservable()
}
isLoadingObservable {
return isSuccessSubject.asObservable()
}
}
This has to be created by hand, for every viewModel, of which there is one for every screen and there is 40+ screens. This same structure is copy / pasted into every viewModel. As mentioned above I would like to make this all generic. Have a generic protocol for all viewModels to define 1 Observable, 1 local variable of generic type and handle the cast back automatically. The method to trigger all the business logic could also have its name standardised ("load", "fetch", "processData" etc.). Maybe we could also figure out a few other bits too. This would remove a lot of code, as well as making the code more readable (less messy), and make unit testing much easier. While it could never do everything automatically we could test the basic responses of each viewModel and have at least some testing done by default and not have everything be very boilerplate-y and copy / paste nature.
The guys think that subscribing to isSuccess and / or isError is perfect Rx + MVVM. But for some reason subscribing to status.filter(success) or status.filter(!success) is a sin of unimaginable proportions. Also the idea of multiple buttons and events all "reacting" to the same method named e.g. "load", is bad Rx (why if they all need to do the same thing?)
My thoughts on this are:
- To me its indentical in meaning and architecture, one way is just significantly less code.
- Lets say I agree its not textbook, is it not worth bending the rules to reduce code.
- We are already breaking the rules of MVVM to introduce coordinators (which I hate, as they are adding even more unnecessary code), so why is breaking it to reduce code such a no no.
Any thoughts on the above? Am I way off the mark or is this classic Rx?16 -
You cant be a recognzied as a good developer, untill you are a good tester or say produce least bug free code. You should do thorough testing of your code before handing over to QA. I lacked the skill of good unit testing, so have suffered alot in past years.1
-
I've been working for two days (after work) on my blog idea...
Man I forgot how fun it is to work on your own projects, and the stuff I learn at the moment... It is insane!
I am currently a very happy developer, hopefully I can keep this up.
I still have to look into automated unit testing and code formatting checks with github though, cant wait! -
All the repos I have pulled for work have not had any unit tests. (well they have one test that does assert(True))
Until I found 1. One singular repo with unit tests. I get happy. I run said tests against the code in master. Tests fail -
How many people do unit testing?. Am always caught my deadline. I just fix errors in production. The client timeline are not feasible3
-
After writing ~200 lines of code and then unit testing it
THE TESTS ALL PASS!!!
then I run them again just to be sure and they all pass but mocha is saying I am getting 40ms lag on some of my tests...
Noooo!!!
This is meant to be an async message passing system; I cannot have an input lag of 40ms :(5 -
Wrote some unit tests to check for 404 errors that called a fake endpoint key...
Months later create that same endpoint key for unrelated reasons and spend a half hour trying to figure out WHY ON EARTH the 404 tests are all failing...
🤦♂️1 -
*class ends, close laptop*
Ten hours later (right now)
Me: 😶 can't remember why these unit tests failed... Let's run again and see why.
*build success, runs more test cases and tests, all builds fine*
Best feel ever 😎1 -
I've fallen in love with (unit) testing, it just saved my ass from deploying a broken version of my library because of a missing '!'3
-
Writing unit tests on a weekend and catching up on work that needs to be done because I m too busy on weekdays to have time to think about this...
The sad thing is test coverage is shit in the entire code base as boss just decided to start enforcing requirements now... And I have this huge migrating from legacy system project that needs to be merged. And we'll the legacy system is even shittier
So I have to write unit tests for shit code that was never written with testing in mind...
On the other hand I reworked some testing utilities to make it easier... For everyone... I want a huge bonus.... That I probably won't get...2 -
So i'm working with people from another team to bring about a feature. I was wondering, "how come they're churning out so much shit in so little time!?"
Apparently, they make code, merge request to the release branch, and then do unit tests later.
How do people, in good conscience, think that they can skip unit testing for extremely vital components???1 -
Last year for company I work I made OAuth server + SSO discriminated by business unit in php. Well it was quite complex project and security sensitive, so I wrote tests for every piece of code. Then I made client for it with abstractions to be easily extendable, but was too lazy write tests for it.
Anyway, today needed to add new grant auth strategy. Thought, I could also write tests for the client this time. That was the mistake...
I installed codeception (testing framework), tested every class, and then left the main client class for the end where all http communication and other magic happens.
So turns out, I can’t capture function parameters with codeception (at least its not documented), so I can’t assert if data in the end is correct. I mean it’s fucking abstraction on top of phpunit, which can do that, so what the fuck? But ok I probably could just use phpunit, but anyway why the fuck you would create mock abstraction with only 20% of functionality from original implementation? It doesn’t make fucking sense...
In addition, I was testing code written with guzzle http (http client), and that is some pile of shit. Just why the fuck I need to write 20 lines of code just to get a fucking json response...
Fuck this shit, I am not going to test it anymore, it just makes me hate php, I barely can deal with all that angryness inside me. -
Finally back at the HQ and away from Offsite Hell after 18 months!!!!!!!!!!!! Real internet! Coffee on tap! Community of practice meetings! COOODDDEEEE!!!! Also back to devrant. Goodbye Indian devs from hell, j/k they still suck life out of my day with their deprecated ways.
Side note:
Switched to Unreal Engine from Unity recently and my god it is amazing! I definitely prefer being able to use C# with unity vs c++ with unreal but the blueprint system is a great visual programming system.
Unit testing is my new side chick. She wants me to leave my wife; I'm considering it.
Unrelated: Read Dead Redemption 2 is amazing.1 -
Ok ok ok, I will preface this by saying I am still a student so you can assume my complete and utter lack of experience.
There is all this fuss about unit testing and TDD but i still have my doubts about it. How is it that if your code works for certain inputs you can be sure that it will work for whatever can happen after deployment?
I mean, to my understanding testing can assure that some business requirements are cared for but as far as actual code correctness goes I don't see how that is achieved.
As far as i am concerned the closest it comes to complete code correctness is a mathematical type of proof but that should be impossible to be done effectively in an OO language.
How can you be sure that your code is what you think?
(If i have this all wrong please correct me)8 -
Developer just emailed our team a complaint that our logging assembly was resulting in their poor test coverage and they sent a change request to give them the ability to mock the underlying log provider (ex. from the event log to ‘something else’).
Looked at their tests, and they are testing whether or not the .Log was executed (on an exception, if the .Log method was not executed, the test failed), which seemed a bit worthless because we’ve already got coverage in our unit tests.
We had a meeting to discuss the issue.
Me: “I’m OK with changing the logging code if it’s necessary, but I want to understand why.”
DevA: “Logging errors is crucial to the database transaction. If someone removes the logging, the tests should fail.”
Me: “If someone removes the error logging on purpose, then they likely have an agenda and will remove the test validation too. It wouldn’t be an accident.”
DevA: “That’s not my problem. They will have to deal with HR.”
Me: “We purposely prevented someone from intercepting the logging just for that purpose. Your test code already covers the business rule, testing the logging seems out of place. That would like writing a test to make sure the System.IO.File.ReadAllText actually reads all the text from a file. You kinda assume a few smart Microsoft engineers already wrote tests for that.”
DevA: “Yea, I guess that would be silly.”
Got cc’ed an email a little bit ago from DevA to his boss..
“We’re not going to be able to change logging assembly. This may have some impact on our overall test coverage as those lines of code will not get testing coverage. You will have to let the DevMgr know we will not meet our test coverage goals.”
WTF!1 -
Started working as a "working student" in an it company to write unit tests. (which then will be executed automatically - so automated unit tests)
Realised that I write more or less the same code just changing the names and some parameters (sometimes more if it's not an number but a bool for example but it's pretty much the same scheme)
So I bought a tool for 1$ to use "auto complete" on custom templates.(I type testgetbool and the tool replaces this to the test case only asking for the variable name.)
So now I'm writing automated automated tests 😁😅
(which is btw pretty boring but cost & time effective)2 -
When explaining unit testing:
"We tried but every time someone changes something in the database all the tests fail."
*facepalm*5 -
I suck at unit testing. I really fucking suck at it.
Every time I try to write a unit test, I think to myself, what the fuck am I doing? How does this even work? What am I testing? Why do I need to new up 100 dependencies? how do I test this private behaviour from the boundaries of my object? Can I even substitute a Factory delegate? Does that even work? What if my object needs a dependency to have certain state? How do I mock that?
Does anyone have any good reading material to make me not shit at writting automated tests?7 -
Counted it out... 100k LoC frontend & backend... Not a single automated test. No unit testing, no integration testing, nothing. I've been asked to implement a CI server.
Halp5 -
Ahh, this particularly memorable occasion, it’s not much of a “fight” per se, but remembering the events I really want to beat the shit out of those asshats,
Backstory, I was working in a project, big one, my previous one, we had all this “squads” to say, agile teams consisted of several devs, I was happily working in my squad namely squad “A”, until one day by the end of a sprint my PO asked me to help another squad, call it squad “B”,
Curious for the reason as I may be, I ignored it at first, after all having the higher up owing me one is always welcome, A and B are having similar amount of dev team, with A having 1 more Front End developer,
Skipping the boring detail, continue on to my first sprint, I saw problems within the team, the other 4 FE consisted of 2 foreigners (call them “the good guys”) and 2 of our own (same vendor as me, let’s call them “the pricks”),
The ones leading discussions most of the time are the pricks, the good guys usually keep their mouth shut, calm and composed, and when shit happens, the good guys usually fix the problem without any fuss, on the contrary, the pricks threw fit all over the place trying to find somone to blame first,
Skip all the excruciating 2 weeks of trying to guide them in the right way, and talking with their PO, my PO, tech leads, etc, I came across a development of a certain feature, PR already made and waiting for review from a TL, then being the impatient ass B’s PO is, he pushed me to ask for a review from another TL, and the only one available is “the meticulous and perfectionist” TL, which is definitely not my choice in any given order,
Simple math, I assigned my review to TL X, wait a day, it’ll definitely be merged within a day, give it to TL Y, he reviews it immediately, and he’ll find all these shit squad B’s been writing, and then I’ll be spending 3 days trying to clean it up, but no matter, the PO insist on having it reviewed first,
Lo and behold, it happened, I had to refactor all the shit the pricks have been writing, again, I took the high road, until I stumbled upon a piece of code that just doesn’t makes any sense, no matter how exhaustively I put the effort to trace it out, an hour passed by and I decided to ask the pricks, let’s call them #1 and #2, #1 being the senior prick, and #2 being the regular prick but bigger pain in the ass, it went on something like this,
Me: uhh, sorry to bother you guys, but what’s this piece is used for?
#2: huh? Dunno, last guy to touch it was #1
Me: eeh, but the line history says it’s you,
#2: strange, I don’t remember, for testing probably
Me: well TL said to remove this one if it’s unused, I want to know if it’ll affect any functionality
#2: well, go figure
Me: yep that’s why I’m asking
#2: well, if you don’t need it just remove it
Me: again that’s what I’m trying to figure out, will it affect any functionality, since time is pressing I don’t have room for experimenting so I’m trying to find some solution by asking the creator if he might have any insight on this matter
#2: well don’t ask me, try asking #1
Me: dear sir #1 have you the faintest idea of what this piece of scripture might mean?
#1: huh? No idea, #2 wrote it
#2:... I don’t remember, I thought it was you,
#1: see the git blame, it’s #2
Me: guys, since we’re not getting anywhere, I’ll just go against my guts and remove it, so that everyone can live happily ever after,
#2: wait, who’s asking?
Me: the reviewing TL,
#2: yes, who?
Me: mr Y
#2: let’s meet with him
Me: what for?
#2: you said he wants to delete the code, let’s have a chat with him
Me: *not this shit again
#2: what are we waiting for, let’s go,
Me: naah, no need I’ll just delete it as you said it first, sorry, my bad
#2: what’d you say?
Me: I already deleted it, nevermind
#2: why did you do that? If the TL doesn’t like it let’s have a chat
Me: and what would be the point of that? I deleted it already, case closed, I’ll take the responsibility for fixing anything that may come up later, I don’t have time for your childish shit,
#2: *glares at me
Me: *glares back
#1: now, now, let’s all take a step back here, blah blah blah
#2: blah blah blah
And they both starts arguing with each other after #1 tries to act all diplomatic, I left them to their own discussion, and proceed with the PR,
Thankfully removing the piece of code doesn’t affect anything, it seems like #1 or #2 forgot to delete it when fixing the unit test some commits ago1 -
I just reviewed a pull request with a test case like (pseudo code):
# Test MyService
const mock = createMock(myService.myMethod)
.whenCalledWith("foo")
.returns("bar");
assert(mock.myMethod("foo") === "bar"));
Why though? Why are we testing the mock? What is happening here? This test has no reason of being there instead of a fuzzy feeling that we now have unit test to lure us into a false sense of security.
I asked why we don't do an integration test. Response was: "They are slow."
Well, duh, but at least they would actually test something.
What do you gain by asserting that the mock is working the way you set it up?3 -
*Executed maven build*
Me: What's this "no tests found?"
Senior: Nevermind it's not important. Just check if your code works.2 -
One responsibility of our team is general code QA for the entire dev department, DevMgr walks in our area yesterday…
DevMgr: “Has anyone reviewed the new WPF threaded model execution code?”
- everyone on the team responds “no”
DevMgr: “Can we get a review on that code ASAP? If it works as well as the developer said, it’s going to solve the lock up problems users are experiencing and automatic logging of errors.”
DevA: “Well, no amount of code is going to stop users from performing bad searches locking up the user-interface. That code is just a band-aid around the real problem. If the developers would write unit tests first …”
- rant about 5 minutes on unit testing that had nothing to do with why the DevMgr was here
DevB: “Yea, the code probably isn’t written to handle threads correctly. All the threading they’ve done so far is –bleep-”
DevMgr: “Oh, I wasn’t aware of that. Get me the results of the code review and if they don’t have unit tests, delete it from source control and let the developer know it’s not up to our standards.”
OMFG!! You have not even seen the code!
OK, DevA ..what the –bleep- does unit testing have anything to do with the user interface! You know the DevMgr is too dim to understand the separation of concerns. Shut your pompous ‘know-it-all’ mouth.
DevB…what the –bleep- have ever done in WPF? You manage the source control and haven’t written any C# in two years and never, ever written code for any significant project. Take that “handle threads correctly” and shove it up your –bleep-. Pompous –bleep-hole. Go back and watch youtube and read your twitter while the grown-ups get the work done.3 -
I've never written any unit tests for any apps/programs I've developed.
I would tell myself, this time you're going to create some and be a better developer by doing so. I end up just creating the file and that's it.
Most of the bugs are discovered during the user testing phase so I always end up being lazy writing unit tests.
I write very defensive code though so that helps a little but all in all, it's a very bad habit that I need to snap out of4 -
How do you switch from testing while debugging (functional) to TDD unit tests?
Usually I test while coding by just running the use case and making sure while coding, bad inputs are caught/handled.
But most times I start with a general idea of the structure and what the about should be (which essentially would be the functional test case?)
I don't think about how you can break each part or the functions I need until I need them. Then usually start simple and then refactor. And until I'm sure each time I refactor would require changing the tests?4 -
Start with the simple things first then progress gradually.
Though I highly suggest learning unit testing as soon as possible. -
My company never used unit tests. And i would love to educate but i do not know how to unit test properly. I always en up with: if i want to properly test all ins and outs of this class's + operator. I need to add checks for positive number, negative numbers, nan, infinites, nulls etc. Etc. It needs so many tests for something so stupidly simple, that i don't see a way to motivate people to use it.
Am i missing something? Is there a guideline for "ok coverage"? Is testing just that much work and is that why nobody cares until it is too late?
I have been reading a book about working with legacy code. But still i got no answers. Halp!7 -
JS/NODE/MOCHA I HATE U....
SPENT ALL MORNING REVERTING AND DEBUGGING A BRANCH BC SOME UNIT TESTS FAILED.
THE CAUSE WAS NOT IN THE FAILED CASE THO.... IT WAS BECAUSE SOME OTHER JS FILE WAS NAMED *Test.js
ITS NOT A PROBLEM IN A LIVE SERVER BUT IT SCREWS UP THE SERVER WHEN ITS RUN IN MOCHA FOR ITS UNIT TESTING... -
Been wanting to get into OOP and unit testing, haven't found a single semi big project that I can use to study these techniques...
Wrote myself a class when asked to do an API call last week, and I think it looks pretty decent...
Does anyone have a ressource to just see how to do it "properly" on medium sized projects? (100k loc)7 -
"You'll be doing X, and be sure to test everything you do. But we don't do unit testing. They aren't paying us for that."
- PM to intern coming via college (it's like a forced internship that counts as another subject for the degree).1 -
So I finished my tasks for today, and after happily doing some HackerRank and household chores I thought of casually logging into Messenger and see what messages people have for me.
Received a question about unit testing from one of my old company's QA guys. Deleted it. Sorry bro I don't want to think about my old job right now.
Received a notification from my dev shitposting group chat. As usual there's 🥬 going on about his noob dev antics but it's nothing to worry about.
Then I received a call from one of my non-dev friends who was concerned for me. Apparently one of my church buddies called him to express his concern over me wearing shades to Mass. Somehow they concluded that I wore shades to Mass because I did not want to see this guy called E.H.
Except I don't know this E.H. guy! I don't recall ever getting acquainted nor being friends with this guy. Maybe this guy has issues over me for simply existing and so somehow he started the beef.
I had to assure my friends that I am doing fine, albeit yes I am now pissed because of this new beef between me and this mystery guy that I am now somehow dragged into.
Oh Jenny when will you ever learn to avoid social media?
To this mystery guy: I honestly don't know you. I always assumed that you're this guy who lived miles away from the capital with your anti-car takes but that is all. But I have no quarrel with you. So fuck you E.H. for your obsession over my shades and for making my Messenger experience worse for tonight. -
I just want to use Jest to unit test my Typescript classes, but that appears to be impossible!
Testing the compiled Javascript instead doesn't seem to recognize any classname at all :( -
when i look at the code structure of the project i work on with my friends, i always think about how to implement the SOLID principles of bob martin for clean code
... and then i think about the clusterfuck of almost unmaintainable code that has been created over time and all the unit testing that doesn't exist at all and how much time and effort it would need to correct that code and how i realize that i don't even understand the principles and how to implement them
... and then i give up and go on coding even more mess
... and then i repeat😅😖😩3 -
Before I started working, I used to feel like I depended on documentation and the internet a little too much owing to ultra crappy long term memory. After spending some time at my internship going through code written by "professional developers" several years senior to me and trying to write unit tests for it (surprise: the code was in production without having underwent any sort of testing), I feel like the amount of time I spend online reading usage recommendations, alternates for optimisation, best practices for writing clean and descriptive code and all that is a lot more rewarding. Some bad things help you feel good about yourself.

Don't start the first semester teaching racket, especially when you're teaching documentation and unit-testing at the same time.
A few months later it was java's turn (same course), why dont teach that first?1 -
What a mess ^^
From one moment to another unit-tests on my local machine stopped working.
There was a PHP fatal error, because of insufficient memory.
Actually, there was a ducking "unit"-test of a controller action "log".
This action returns the content of the projects log file...
Since this log file grew over the time, PHP tried to assert the response of the controller action which was sized about 400MB.
C'moooooon guys!
What were your thoughts behind this bullshit? ^^ -
So I'm working on some communications app which bridges the main server/database with some equipment on the field. Now this equipment works in a redundancy pair: two cpus, A and B, both connected via ethernet, one active, the other standby/replicating and no comms on it. One obvious requirement is that when this equipment swaps the active cpus the comms app should switch as well. Fair enough, going with this into testing phase.
This guy, from qa, got some instructions from someone else:
1. Trigger the soft switch from equipment so that cpus got swapped.
2. Remove the ethernet cable from the standby unit.
3. Observe the communications.
And the test goes like: cpu A is active, B is standby. Switch is triggered, B becomes active, A goes into standby. The cable is pulled out from cpu B.
Test result: failed, no comms ever4 -
Anyone know how to go about unit testing an application that is made up of:
- Electron
- Node
- React
- Typescript
(React using Typescript of course).
Electron has its own framework (Spectron), people seem to use Mocha with Node, React has its own tools like React testing library (and testing UI components will probably end me) and Typescript seems to play best with Jest - but a special Typescript flavour of Jest called ts-jest is preferable because the only other option is having Babel and its Typescript support that doesn't type check.
I want to beg for the sweet release of death.4 -
How do you implement TDD in reality?
Say you have a system that is TDD ready, not too sure what that means exactly but you can go write and run any unit tests.
And for example, you need to generate a report that uses 2 database tables so:
1. Read/Query
2. Processor logic
3. Output to file
So 1 and 3 are fairly straightforward, they don't change much, just mock the inputs.
But what about #2. There's going to be a lot of functions doing calculations, grouping/merging the data. And from my experience the code gets refactored a lot. Changing requirements, optimization (first round is somewhat just make it work) so entire functions and classes maybe deleted. Even the input data may change. So with TDD wouldn't you end up writing a lot of throwaway code?
A lot of times I don't know exactly what I want or need other than I need a class that can do something like this... but then I might end up throwing the whole thing out and writing a new one one I get a clearer idea of what i or the user wants or needs.
Last week I was building a new REST API, the parameters and usage changed like 3 times. And even now the code is in feasibility/POC testing just to figure out what needs to be used. Do I need more, less parameters, what should they be. I've moved and rewritten a lot of code because "oh this way won't work, need to try this way instead"
All I start with is my boss telling me I need an API that lets users to ... (Very general requirements).15 -
Writing code for software that was deprecated since 2015 it's a nightmare. More when the unit tests take way more time than the actual fix or feature. Just kill it with fire
-
I have reached the conclusion that angular and tdd don't go together well. Component tests take forever to run.
-
In my first few months of my first dev job, I written this fragile piece of code in, trigger warning, PHP that sent out email reports to my clients. It was a two men team, and we have no clue about TDD or how to do unit testing for such code. We would just run that piece of code manually do send out dummy emails to ensure things were working.
One day the code broke. I was told by my boss to fix it. Spent the entire day trying to fix but couldn't get anything done. Finally at around 7pm my boss came by and asked why is it I couldn't get it fixed. He helped me troubleshoot and fixed it. And subsequently told me "c'mon man you're better than this."
It turns out that he changed a part of a code that was supposed return an array of strings to an array of objects, adding a second attribute that wasn't even in use.
So what that meant is that he changed a piece of working code, to include a property he didn't need, committed and push to production without even manually testing it. AND TALKED SHIT TO ME.
That was the day I learned git blame and began my journey on TDD. -
Is it actually required to write unit tests in microservices?
every time i write them it feels like im just redundantly copying a method...
Dont get me wrong, im not against testing, I am using test environments, integration tests and mocks, but unit test seem kinda redundant to me.5 -
Our systems lead is trying to tell our software person how much adding unit tests would cost. It also sounds like he wants TDD to be added in after the fact. And he's bitching because the software guy won't move forward with it until we get it with the customer. He also wants all of them automated, but doesn't want to accept that that is going to cost a lot. Like a lot, a lot. This is a guy who doesn't know algorithms (had to explain dykstra to him), doesn't understand the tech stack we are using (I had to explain .net versions, the JIT compiler, and garbage collection to him), and seems not to understand hardware (I had to explain floating point math to him), yet he feels qualified to tell us how long it is going to take us to implement automated unit tests for major, complex features.

Why does it have to be so difficult to get unit tests to run? Spent about an hour yesterday trying to get a single test class to run and it kept complaining about a compiler error in a completely different module. Went to the file and there was no error. WTF?!
In the end, checking the “delegate build actions to gradle” box made it go away. why..... -
1) receive functional requirements
2) create functional specification, post it on forum (no jira)
3) create memo document, post it on forum (no jira)
4) create analysis document with actual code changes without seeing the code (wait for step 8), post it on forum (no jira)
5) receive review on analysis document, fix it and post (no jira, redmine etc from now till the end of rant)
6) after analysis is approved make a checkout request
7) source code manager checkouts files from svn and posts them on forum along with the files list
8) you make actual changes to the code, post changed sources on forum
9) source code manager makes a review to check that amendment commet is present in source code and is properly tagged, and every line of code chnged is properly tagged (you are not allowed to delete anything, not even one space, you need to comment it (and put an appropriate tag))
10) after you passed review you fill in standard compilation request form
11) you code is compiled and elf is put on testing stand
12) you fill in "actual behaviour" and "expected behaviour" columns near description of changed function in template of unit test plan document (yeah we have unit testing) and post it on forum
13) if testing ok changed sources and compiled elfs along with its versions (cksum) commited to svn (not by you, there is a source code manager for that)
14) if someone developed function in same source file as you "commited" he is warned by source code manager and fills checkout request form again
15) ...2 -

The job description of my internship:
You must be able to understand the complexities of receiving a unit test that you are told needs only mock data in the test database, but has never worked since it was written by a contractor a year ago. No one knows how the unit test works and requires testing a complex algorithm involving graph theory that you have not learned about yet. The task starts at 1 complexity and turns into a 13. -
How do you think about unit testing/TDD when writing apps? (I'm working this at 3am so might be a bit messy... Just a thought I woke up to).
Whenever I write an app, I don't write unit tests but as I'm developing I may create test functions for specific parts that I run to validate a specific component is working before moving onto the next.
So first, when I get a problem, break it up into components based on the requirements. It's usually sort of input, processor, output sequence.
Where the processor is essentially the core app. And so I start coding it, referring to the input thru an interface, model objects, adding fields as I go along (assume no matter what the input, I will get these before the logic is called). I may add some more interfaces as well for other data I may need but I know won't be going in the first input.
So I write all the logic, functions needed to get a basic app to run that does what I am writing the app for.
Only then do I write a test functions passing in different parameters to make sure the logic and response is what I want and making fixes as necessary. At that point I basically have the simplest version of the app.
(I guess this is sort of like mocking?)
Then build outwards implementing and testing components as I go along and may do some simple refactoring/redesign. (I guess all these tests are functional then, have to start the whole app).
And finally when I have the basic requirements fully complete I will add the "nice to haves" on top via refactoring of specific logic in specific components. Again testing by running the app maybe with simple inputs.
I guess now I'm thinking how do you write unit tests/TDD if the app keeps changing (via adhoc refactorings) as you are creating it? -
Coworker: "Hey, so I discovered this library that automatically brings up and tears down local containers to perform unit tests on data sources"
Me: "Sounds neat"
Coworker: "Yeah, I've been messing with it locally, and it means we don't need to have the data sources installed on our machines or rely on the ones in the testing environment."
Me: "That's good"
Coworker: "Just a shame I had to roll back our testing framework to a previous version and refactor the code in all our other tests as a result."
Me: "Wait what? *looks at documentation* It says they support the newer framework"
Coworker: "Yeah, but I couldn't get it to work. So I'm just gonna make a PR for it, okay?" *Proceeds to make a PR, approve and merge the code before I can comment further on the changes*
Welp, there goes all my motivation to get anything done for the rest of the day.3 -

Using Java is there a framework for building functional tests?
For unit testing we use JUnit but when I'm writing my code, often I need to debug against an actual db, for example, to be able check it actually will work and return the results I expected (and mocked in the unit test).1 -

I have my 121 in a few days with my new manager and am trying to get a raise either through moving from junior to mid level dev or being given a significant raise , am being paid a tad below the London market rate's lower range for my skill level.
Any advice on how to approach the topic?
Some bits of my background:
I got almost 4 years of exp :
almost 2 working there...
6 months short term contract as a ruby sql dev another company...
1.5 years worked for an abusive joke of a company who took advantage of my naivety since i was fresh out of uni ( did stuff like pressured me to add more features to a pojo system i made for them) barely learned anything there since i was the only IT person there developing solo, the project lasted 1.5 years and was a total mess to finish, so am not too sure of factoring it into my years of exp.
My Qualifications are:
bsc in information systems
Msc in enterprise sw engineering
My "new" Manager is seeking to retire real soon.
The company isn't doing too well but we just landed 2 big customers who are buying the product my team is working on
I Am one of two last devs on my team and we are barely holding on with the load, can't afford the time to train a newbie to join us
my department is soon to be sold (soon according to what mgr says). They have been saying so for 10 months now.
Last year , since the acquisition Is taking so long and funds were running out We were hit by a wave of redundancies which slashed our workforce in august/ july, told we could last till march this year on our funds . Even senior staff were on a reduced work week...but since we Got new customers then money should be coming in again , this should mean thats no longer the case. Even the senior staff have returned to 5 day work weeks.
Am being given only JavaScript work to do despite being hired as a junior java dev, my more senior colleagues dont wanna even touch js with a long stick
Spoke to 3 recruiters , said they got open roles in the junior- mid level range that pay the proper market range if am interested to put my cv through.
Thats like 25% more than I currently make.
Am a bit scared to jump into a mid level position in another company because i lack a bit confidence in my core java skills.
although a senior dev who used to be on my team thinks i can do it.
i recon i can take on the responsibilities of a mid level dev in me existing company since am pretty familiar with the products
I dont get to work with senior devs and learn from them since we are so stretched thin, hence am not really getting the chance to grow my skills
I know i have gaps in my knowledge and skills having not been able work in java for a while hasn't allowed me to fix that too well. I badly need to learn stuff like proper unit testing, not the adhoc rubbish we do at the moment, frameworks like spring etc
Since I have been pretty much pushed into being the js guy for the large chunks of the project over the last year , its kinda funny am the only guy who has the barest idea how some of the client facing stuff works
The new manager does seem to be a nice guy but he is like a politician, a master bullshitter who kept reassuring all is well and the company is fineeee (just ignore the redundancies as the fly past you)
The deal for thr aquisition seem to have sped up according to rumors
And we heard is a massive company buying us, hence things might pick up again and be better than ever
Any ideas how to approach the 121 with him?
Any advice career wise?
Should i push for a raise ?
promotion to mid?
Leave to find a junior to mid level position?
Tought it out and wait for the take over or company crash while trying to fill the gaps in my knowledge ?
Sorry for the length of this post2 -
I'm starting to gain a dislike for OOP.
I think classes make it easy for me to think of the entities of a problem and translate them into code.
But when you to attempt to test classes, that's when shit hits the fan.
In my opinion, it is pointless to test classes. If you ever seen test code for a class, you'll notice that it's usually horrible and long.
The reason for this is that usually some methods depend on other methods to be called first.
This results in the usual monolithic test that calls every goddamn method on the class.
You might say "ok, break the test into smaller parts". Ok. But the result of that attempt is even worse, because you end up with several big tests cases and a lot of duplicate code, because of the dependency of some methods on others.
The real solution to this is to make the classes be just glue: they should delegate arguments onto functions that reside on its own file, and, maybe afterwards emit events if you are using events.
But they shouldn't have too much test code classes though. The test code for classes should be running a simple example flow, but never doing any assertions other than expecting no exceptions.
For the most part, you'd be relying on the unit testing that is done for each delegated function.
If you take any single function you'll see that it's extremely easy to write tests for it. In fact, you can have the test right next to the fuction, like <module>.xyz <module>.test.xyz
So I don't think classes shouldn't be used at all, they should just be glue.
As you do normal usage of this software this way, when a bug is discovered you'll notice that the fix and testing code for this bug is very usually applied to the delegated functions instead of being a problem of classes.
I think classes by themselves sound sane in paper, but in practice they turn into a huge fucking messes that become impossible to understand or test.
How can something like traditional classes not get chaotic when a single class can have x attributes and y methods. The complexity grows exponentially. And sometimes more attributes and methods are added.
Someone might say "well, it's just the nature of problems. Problems can have a lot of variables".
Yeah, but cramming all of that complexity into a single 200 lines class is insanity.12 -
Original class has 185 LoC, unit test class have 315.
But it's one of the most important classes, with most states and corner cases.
And, thanks to unit tests, one of the few classes I'm almost proud of. -

Unit testing with NSubstitute and Autofac
For the most part, I find it a lot simpler than SimpleInject (hmm) and Moq, which I have used previously.
But there are still some of those 'Oh, for fucks sake!'-gotchas.
I was trying to test a class today where I wanted to substitute all other methods in the class than the one I wanted to test == an actual unit test.
I had previously found out how to do this:
1. Make sure the methods that should be substituted are internal to allow substitution.
2. Substitute class with Substitute.ForPartsOf<T>(args)
3. Set up methods that should not be called with instance.When(a => a.Method()).DoNotCallBase()
This way, you can unit test a class properly and only call the method that you want to test, and also control the return values of the other methods if needed.
So as I said, I have used this before to great effect. But today I just could NOT get it to work! I checked and rechecked everything but the test code kept calling the implementations of the substituted methods!
I even called over another dev for help, but he couldn't see the problem either.
Aargh!
I scoured the internet, but everyone just told me what I already knew: follow the 3 steps, and all is well. Not so!
I ALMOST considered doing the test improperly, as in, increasing the scope beyond that of the method I wanted to test.
But then it hit me... My project was missing this line in AssemblyInfo.cs:
[assembly: InternalsVisibleTo("DynamicProxyGenAssembly2")]
I always add a line to make internals visible to the test project, but I had forgotten that NSubstitute needs this line as well to work properly.
Sometimes when a test fails it will tell you that you are missing this line. And sometimes it just doesn't work.
Maybe I will remember this in the future now. Maybe 😅 -
Haven't done much work on my game since December. Ok so I havent done anything on my game since December. Learned Mockito and JUnit formally (finally) because that's what we'll be using at work.
Never really learnt unit testing prior, just knew it's power. I just need to find the right unit testing and mocking frameworks that work well with .net, C# and Unity3D and I'll be great.
I'll finally attempt to properly test that (those) annoying part(s) of my game. So many vectors to work out and often the object is moved to or along the wrong vector.
I'd always only imagined having to use stubs which is why I've never understood how unit testing would really help in such a dynamic environment as video game development. Especially as a one man team. Mocking is about to be my lifesaver.
Anyone able to suggest a good testing and/or mocking framework for C#, .Net, Unity3D? -
New Project
M: Hey, check these two processes. Both took different paths for the same input. Here are the logs. Both are the same though.
Me: Ok... do we have a debugger?
M: No this product doesn't have a debugger
Me: Any unit tests i should know of?
M: We don't do unit testing. Everything is done in Integration Testing.
Me: Ok. So how can i check the db for this?
M: You can't, the access is restricted. You'll have to raise a ticket to other team with the sql output you need.
Me: Ok. So I hope you have the schema at least.
M: Yes we have the schema. But there was some issue last week so the values might not be there in the correct column. They may or may not be present where they are supposed to be.

Today I escape from the clutches of the legacy iOS project ive been stuck in for about a year and a half.
Starting on a new team, totally different stack (TypeScript/Angular).

Life is good. -
I'm currently developing a Node.js tool. Now I want to write some unit tests, but I never wrote unit tests for a node app before and I don't know which framework I should use.

This is brilliant example of why integration testing is so much better than unit testing https://twitter.com/withzombies/...4

I'll do the tests later on it'll be fine. 3 releases on, There are bugs everywhere - I cannot handle the regressions. Why'd this happen..Yeah.. Really need to do some proper TDD at some point.

Hey, can someone point me to a sample project (if it exists) on the best way(s) to stucture code for Serverless architecture that includes GraphQL and unit testing?
Preferably in NodeJS. I'm more interested in the code structure than anything else. -
Online resources that discuss testing recommend the following pattern when writing your unit test method names:
given[ExplainYourInput]When[WhatIsDone]Then[ExpectedResult]()
This makes developers write extremely long test method names.. and this is somehow the acceptable standard? There must be something better.. I think I've seen annotations being used instead of this.5 -
Upgrading my tech skills.. Once again I feel my personal my personal dev environment and told are much more up-to-date than what I use at work.... Though the book Kim reading is on TDD and was written 3 years ago.
Maybe I should read another on in cloud services and ML... but don't have any motivation for these topics.
I need TDD for work because now we're emphasizing unit test coverage...
I usually only use manual functional tests to verify the final outputs as either the testing framework is broken (JS) or I don't have time to relearn the frameworks for the particular language...
Anyway got off topic... So questions after:
1. Do you ever feel your technologically always more ahead than what you do at work and essentially you bring skills to the job but you don't learn much out of it?
2. How do you test? I actually got into a bit of a argument/discussion with my colleagues about how to implement unit tests. Apparently there are 2 ways to test? Black box vs WhiteBox. She said she tests only Public methods using mock inputs, dependencies. She read online and seems there is an opinion that should only test public functions and if you can't then your app is designed incorrectly, not separated enough.
For me I test the private functions individually (WhiteBox/Java reflection) because the public one is like generateReport and as a whole is like a Pachinko machine, too many unique paths that would need a test case for.
So thoughts? Yes sorry for turning it into a remake I guess...25 -

Power BI: wonderful tool, pretty graphics, and can do a lot of powerful stuff.
But it’s also quite frustrating when you want to do advanced things, as it’s such a closed platform.
* No way to run powerquery scripts in a command line
* Unit testing is a major pain, and doesn’t really test all the data munging capabilities
* The various layers (offline/online, visualisation, DAX, Powerquery, Dataset, Dataflow) are a bit too seamless: locating where an issue is happening when debugging can be pain, especially as filtering works differently in Query Editing mode than Query Visualisation mode.
And my number 1 pet peeve:
* No version control
It’s seriously disconcerting to go back to a no version control system, especially as you need to modify “live code” sometimes in order to debug a visual.
At best, I’ve been looking into extracting the code from the file, and then checking that into git, but it’s still a one-way street that means a lot of copying and pasting back into the program in order to roll back, and makes forking quite difficult.
It’s rewarding to work with the system, but these frustrations can really get to me sometimes2 -
Does anyone have experience with unit testing AutoCAD plugin applications? And || or UI testing?
Because you need a running AutoCAD application to test commands and functions it's very difficult to test the AutoCAD related methods.
I would like to know how you do it. -
So I am working on a Java library with minimal dependencies. Everything goes well until you dont want clients knowing how to construct the internal objects and you dont have a depenency injection framework to help.
Unit testing becomes that bit trickier1 -
Had a 2 hour meeting where I was told to use Specflow for all of our unit and integration testing. It'll be easier for the business to read.
Spent 3 hours setting up the tests for the scenarios for the next story.
Had another 2 hour meeting where they decided it was a bad idea to wrap all unit and integration tests in gherkin...because the business users don't want to read gherkin... -
What should I do, I have a central function that is not documentated and no test-cases are written for it. I have no clue what the method should really do, I know that it works in 99.9% of all cases otherwise we had much more bugs. Now there is one Unit-Test that reports an issue. I tracked it down to this method, no one touched the method nor the unit-test.
My logical thinking says that there is one statement missing, but it could also fuck up another part of the code... (This project has a bad testing coverage :'( )
What would you do?
- copy paste the method for this special case (I would hate me so much for breaking DRY)
- inheritance?! (Would make it more complex and then it would be still untested / undocumented)
- YOLO changing oO?! (hope for luck, just joking)
P.s it's an edge case unit test, the client / customer probably wouldn't realised it if it happens -
What stack are you using to test your angular app and why?
We’re using Karma + Jasmine for writing unit tests, because it’s the default, and run them on GitLab CI in a Docker container. For UI testing we don’t use the default Protractor but Selenium, because we haven’t found a way to run Protractor tests with a dedicated webserver.1 -
For the old school gamers out there, today I realized that the method by which the Temporal Security Annex detects temporal disturbances in the game The Journeyman Project is, effectively, unit testing time itself.

I have actually two, but I'll write the other one in the week.
So we had classes about software engineering. The class was interesting but the teacher wasn't. Too soft, too slow, too low, too monochord (usual french), it was boring. So we ended up not listening to him. Kinda regret this.
We got a first exam, where we were in group to develop a Test Manager for Unit Test (yep.)
We had instructions, like the note would be multiplied by the percentage of coverage of code, etc.
The thing is, we really didn't get the point of the project. Now that I think of it, it seems obvious, but it wasn't back then as it was too new. In the four people of our group, one worked real hard on it, I tried to do my best, the others too.
But like I said, I didn't get back then the point of the topic, which is to apply design pattern, unit testing, etc. It was furstating af and we ended up with a 9/20.
I got the point of the topic only for the second exam, the most classic one, on a paper sheet with questions to answer. (We were allowed only one cheatsheet, I understood the topic while doing it. Sad, huh ?)
