Yesterday: Senior dev messages out a screenshot of someone using an extension method I wrote (he didn’t know I wrote it)..
SeniorDev: “OMG…that has to be the stupidest thing I ever saw.”
Me: “Stupid? Why?”
SeniorDev: “Why are they having to check the value from the database to see if it’s DBNull and if it is, return null. The database value is already null. So stupid.”
Me: “DBNull is not null, it has a value. When you call the .ToString, it returns an empty string.”
SeniorDev: ”No it doesn’t, it returns null.”
<oh no he didn’t….the smack down begins>
Me: “Really? Are you sure?”
SeniorDev: “Yes! And if the developer bothered to write any unit tests, he would have known.”
Me: “Unit tests? Why do you assume there aren’t any unit tests? Did you look?”
<at this moment, couple other devs take off their head phones and turn around>
SeniorDev:”Well…uh…I just assumed there aren’t because this is an obvious use case. If there was a test, it would have failed.”
Me: “Well, let’s take a look..”
<open up the test project…navigate to the specific use case>
Me: “Yep, there it is. DBNull.Value.ToString does not return a Null value.”
SeniorDev: “Huh? Must be a new feature of C#. Anyway, if the developers wrote their code correctly, they wouldn’t have to use those extension methods. It’s a mess.”
<trying really hard not drop the F-Bomb or two>
Me: “Couple of years ago the DBAs changed the data access standard so any nullable values would always default to null. So no empty strings, zeros, negative values to indicate a non-value. Downside was now the developers couldn’t assume the value returned the expected data type. What they ended up writing was a lot of code to check the value if it was DBNull. Lots of variations of ‘if …’ , ternary operators, some creative lamda expressions, which led to unexpected behavior in the user interface. Developers blamed the DBAs, DBAs blamed the developers. Remember, Tom and DBA-Sam almost got into a fist fight over it.”
SeniorDev: “Oh…yea…but that’s a management problem, not a programming problem.”
Me: “Probably, but since the developers starting using the extension methods, bug tickets related to mis-matched data has nearly disappeared. When was the last time you saw DBA-Sam complain about the developers?”
SeniorDev: “I guess not for a while, but it’s still no excuse.”
Me: “Excuse? Excuse for what?”
<couple of awkward seconds of silence>
SeniorDev: “Hey, did you guys see the video of the guy punching the kangaroo? It’s hilarious…here, check this out.. ”
Pin shoulders the mat…1 2 3….I win.6 -
Fuck today was weird.
Today I received almost half a million on my bank account. 😯
Someone changed the ancient cryptic billing system. My user account at work has id 32 in the database, and the dev referenced the size of the creditor id instead of the of the value of the ids itself, and they're u32 ints... So ALL the money moving through our platform was accidentally transferred to my associated bank account.
For all the unit tests we have, this bug tumbled right through.
And no one at finances thought a transfer that big, to a backend dev they know by name, was suspicious — with almost no money going to other creditors...
That worries me a bit. The fact that this shit can happen, even at high test coverage, just because someone mindlessly did a wrong autocomplete or something.
Of course I will send it back... after two weeks and a few hundred € of interest.12 -
Dev: "Ah, I finally fixed that code I was working on the other day and got it pushed to staging!"
Almond: "Ah, great! What was the issue in the end?"
Dev: "It was an odd one - it wasn't actually my code that was the issue, there was a bunch of other code getting in the way."
Almond: "How do you mean?"
Dev: "It kept complaining about something called a "unit test" failing - so after a while I found the right unit tests, deleted them, and now it works great!"
Almond: "..."11 -
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.

In unit test
Me: *uses everything I have , writes a program with my own logic, tries to make it better by adding some user friendly features and also documents the whole code*
My Friend:*copies from textbook*

ME:9/10
HIM:10/10
"Your code isn't present in the textbook, so I can't say if it'll work but still I've given you marks" -_-
What kinda system is that -_-12 -
Sometimes I'm lazy and if I'm writing unit tests and there's a complicated case to test I'll just skip it.15

Looks like I'm getting fired on Wednesday :)
Long story:
*I add first unit tests to project.
*Boss adds new functionality and breaks all the tests so I can't compile and write more for what I'm working on.
*Boss is very fragile and cannot handle any comment that can possibly be taken as a slight against him.
Me: "I wanted to ask what our policy on unit tests is please? Because we haven't really said how we are treating unit tests, and everyone myself included is not thinking about them. I also haven't added tests when I fixed bugs and this time your changes broke the tests"
Boss 10 minutes later: "I want to speak to you in private".
Boss: "you are too forceful and direct. You said I should have added tests."
Me: "yeah but I didn't mean in a nasty way"
Boss getting louder and more aggressive: "You are too forceful"
Me: "I didn't mean it in a bad way"
Boss: "I didn't want to add tests for that!"
Me: "then why add any tests?"
Boss: "Fine we are not having this conversation now!"
*Boss storms out
I decided I can't speak to the guy about anything without upsetting him spoke to the manager before I quit because I can't work like this.
That resulted in a meeting with my boss, his boss and the head of HR where I ended up savaging him and told them I can't bring up anything as I can never tell if it will offend him and that I spend ages writing emails and trying to document communications because I just can never tell if I will upset him. Also that I cannot bring up any ideas because I can't tell if he will somehow get offended and that I can't even write code because if I change something he wrote at some point he will get angry.
My boss claims that I am extremely forceful and disrespectful and that I am constantly insulting him and his decisions.
We go back over a ton of shit and I refute everything he says. In the end I have to have a meeting with him on Wednesday where we either get things straight, he fires me or I quit.
I think at this point that our relationship is too fucked for him to be my team lead on a 6 man team.
Side note I keep bringing forth ideas because we have one database shared between 6 Devs, no pull requests (apart from mine and another new guy), no test driven development, no backlog, no team driven story pointing, no running tests before merging, no continuous integration setup, no integration tests, no build step on merge, no idea of if we are on track to our deadline other than his gut feeling, no actual unit tests backend - just integration with a test db, no enthusiasm to learn in the team and no hope.23 -
Newspaper: This CEO is one of the top entrepreneurs in the country, a true tech visionary shaping the future.
--- 3 months previous ---
Lead dev: O2 have said they are will pre-install the app on all their Androids but they need documentation from us.
CEO: documentation? on what?
Lead dev: Our unit test coverage, bugs found / fixed, security scan results, performance assessment, if and where its storing any data etc.
CEO: Ah were not doing any of that crap, bloody unit tests, its not necessary, tell them no.
lead dev: ..... eh ok
O2: *approved*
... true visionary, well done to everyone involved.3 -
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 -
I'm convinced code addiction is a real problem and can lead to mental illness.
Dev: "Thanks for helping me with the splunk API. Already spent two weeks and was spinning my wheels."
Me: "I sent you the example over a month ago, I guess you could have used it to save time."
Dev: "I didn't understand it. I tried getting help from NetworkAdmin-Dan, SystemAdmin-Jake, they didn't understand what you sent me either."
Me: "I thought it was pretty simple. Pass it a query, get results back. That's it"
Dev: "The results were not in a standard JSON format. I was so confused."
Me: "Yea, it's sort-of JSON. Splunk streams the result as individual JSON records. You only have to deserialize each record into your object. I sent you the code sample."
Dev: "Your code didn't work. Dan and Jake were confused too. The data I have to process uses a very different result set. I guess I could have used it if you wrote the class more generically and had unit tests."
<oh frack...he's been going behind my back and telling people smack about my code again>
Me: "My code wouldn't have worked for you, because I'm serializing the objects I need and I do have unit tests, but they are only for the internal logic."
Dev:"I don't know, it confused me. Once I figured out the JSON problem and wrote unit tests, I really started to make progress. I used a tuple for this ... functional parameters for that...added a custom event for ... Took me a few weeks, but it's all covered by unit tests."
Me: "Wow. The way you explained the project was; get data from splunk and populate data in SQLServer. With the code I sent you, sounded like a 15 minute project."
Dev: "Oooh nooo...its waaay more complicated than that. I have this very complex splunk query, which I don't understand, and then I have to perform all this parsing, update a database...which I have no idea how it works. Its really...really complicated."
Me: "The splunk query returns what..4 fields...and DBA-Joe provided the upsert stored procedure..sounds like a 15 minute project."
Dev: "Maybe for you...we're all not super geniuses that crank out code. I hope to be at your level some day."
<frack you ... condescending a-hole ...you've got the same seniority here as I do>
Me: "No seriously, the code I sent would have got you 90% done. Write your deserializer for those 4 fields, execute the stored procedure, and call it a day. I don't think the effort justifies the outcome. Isn't the data for a report they'll only run every few months?"
Dev: "Yea, but Mgr-Nick wanted unit tests and I have to follow orders. I tried to explain the situation, but you know how he is."
<fracking liar..Nick doesn't know the difference between a unit test and breathalyzer test. I know exactly what you told Nick>
Dev: "Thanks again for your help. Gotta get back to it. I put a due date of April for this project and time's running out."
APRIL?!! Good Lord he's going to drag this intern-level project for another month!
After he left, I dug around and found the splunk query, the upsert stored proc, and yep, in about 15 minutes I was done.1 -

Same fucking dev: Can't merge to master coz CI is screaming at you? Merge locally and FORCE push.
Me: Hi, I'm blocked. I can't merge to master coz of this failing test, can we get on a quick call and figure this out?
Same fucking fuckface dev: *after 3 fucking days* Yeah, I don't know why it's failing.. the results seem to be inconsistent..
Jesus Christ. I am so close to leaving this side-project because of the frequent shit I have to go through with this fucking idiot.

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.

I was assigned a girl that's new to the industry (but with a master's degree).
I had high hopes, as people told me she is quite a curious fellow. As I am just a junior Dev with 2 yrs of experience Ididn't know if I could handle her.
We started working on a project. Which was a change request for a previous project I had developed. I gave her 2 days to read and understand the functional requirements of previous project and this CR. Then explained everything too.
Then I gave here another 3 days to read the previous design document to learn how this code worked.
I asked her multiple times if she has any questions. She said she got everything. Cool.
One week goes by. We start to code the CR while she is shadowing me. I explained why we chose one of the two approaches. And why we are making any of the changes. She as usual nodded in agreement.
I asked her to create Unit test cases.
She couldn't write even one. So, I quizzed her, she knew nothing about the project! Nothing at all!
FUCK!
I wrote down the test cases in short hand and told her to document it (by reffering previous UTC). She wrote the test cases in short hand in the document. And she reused the previous document and did not even clean it out.
After fixing the document I asked her to execute them. But nope, she doesn't even know how the application flows for this project. FML.
It took her 3 days to write and test 8 test cases.
Now she is assigned to me in another project. This one is more complicated. And I gave her a function skeleton to complete. I figured that it will take me 15 minutes so let's give her a day. But nope. 3 days no progress.
I get it someone might not be quick to grasp something. But you know what grinds my gears? That even after this you act like a know it all! Fuck! For someone who hasn't worked with her she is the most dilligent developer.
How the fuck does someone survive masters and suck so bad!22 -
"Trinidad And Tobago" changed their country name to "Trinidad & Tobago", and the .Net framework reflected that change.

QA: You need to write a test script for your new web app before it can go live
Me: ok, I'll write some tests in PHP unit and automate the tests.
QA: Oh, can you do that? We just normally write a list in excel then go through each line and write pass or fail at the end.
Me: yeah, good one.
QA: Umm, I'm not joking.
Queue awkward silence...4 -
For a week+ I've been listening to a senior dev ("Bob") continually make fun of another not-quite-a-senior dev ("Tom") over a performance bug in his code. "If he did it right the first time...", "Tom refuses to write tests...that's his problem", "I would have wrote the code correctly ..." all kinds of passive-aggressive put downs. Bob then brags how without him helping Tom, the application would have been a failure (really building himself up).
Bob is out of town and Tom asked me a question about logging performance data in his code. I look and see Bob has done nothing..nothing at all to help Tom. Tom wrote his own JSON and XML parser (data is coming from two different sources) and all kinds of IO stream plumbing code.
I use Visual Studio's feature create classes from JSON/XML, used the XML Serialzier and Newtonsoft.Json to handling the conversion plumbing.
With several hundred of lines gone (down to one line each for the XML/JSON-> object), I wrote unit tests around the business transaction, integration test for the service and database access. Maybe couple of hours worth of work.
I'm 100% sure Bob knew Tom was going in a bad direction (maybe even pushing him that direction), just to swoop in and "save the day" in front of Tom's manager at some future point in time.
This morning's standup ..
Boss: "You're helping Tom since Bob is on vacation? What are you helping with?"
Me: "I refactored the JSON and XML data access, wrote initial unit and integration tests. Tom will have to verify, but I believe any performance problem will now be isolated to the database integration. The problem Bob was talking about on Monday is gone. I thought spending time helping Tom was better than making fun of him."
<couple seconds of silence>
Boss:"Yea...want to let you know, I really, really appreciate that."
Bob, put people first, everyone wins.11 -
5 years ago, in my first week of starting this particular job, the CTO casually mentioned they'd been struggling with a bug for years. Basically, in the last few days of the year, it seemed that records were jumping a year ahead, with no rhyme nor reason why. Happened every year, and wasn't linked with them deploying new code. (Their code was a mess with no sane way to unit test it, but that was a separate issue.)
I happened to know immediately what might be causing it - so I ran a case-sensitive search in the codebase for "YYYY", pointed out the issue, explained it, then committed a fix all in about 2 minutes.
I was told I'd officially passed my probation.
(Search for "week year vs year" if you're curious & the above doesn't ring any bells.)6 -
I recalled a seemingly simple task I took on.
We were building a booking system, and I had to figure out how to retrieve bookings by a certain date range.
Upfront, the tasked seemed simple until I realised I had to both figure out the logic and the SQL statements needed to retrieve all bookings within a certain date range in one query.
I ended up drawing a model to help me visualise the various date-range criteria to be satisfied. And used unit tests to help me think through each date range criterion and make sure they were accurate. Some were obviously from paranoia, but better to be safe than sorry...
After that, I had wrote down raw SQL directly into Sequel Pro first to make sure my query logic was accurate too, before translating into something the ORM equivalent. This was when I learned how to define and use variables in SQL. The variables were throw-away code; I just didn't want to have to hard-code the test date-ranges over and over again; minimise chances of spelling errors.
Needless to say, felt my problem-solving skills went up one level after this task. Saw my coding style and unit tests improve. And also the thought processes that go into how to maintain code quality...

Worst of many. Had to work with someone who could be accurately described as a monkey in trousers with strategically cut fur.
Him: "I have refactored code now I have to refactor all your goddamn unit tests"
Me: "so?"
<silence>
<checks his commit>
Me: "why have you commented out every single line in all the unit tests?"
Him: "I DON'T BELIEVE WE SHOULD HAVE ANY UNIT TEST. THEY ADD TIME".
Me:"You cannot be serious. Apart from the obvious mistake in judgement why in the name of blue buggery fuck did you not delete the files? Have you not heard of source history?"
Him:"...."
I became his lead.

I found an interesting job post on SO, I decide to apply. It comes with a programming test. A simple unit test that must pass (see current-1 post). I get it passing, go to send off my resume and code and the fucking email they supplied isn't valid or active. Fuck you. Eat dicks. Useless fucking HR.

Why... why the fuck do people write unit tests and then comment out the god damn fucking assertion lines....
Like what the flying fuck? Cool, we can get some code coverage marks but for fuck sake actually let your tests do their fucking job!!!
Oh, the asserts fail?
Well fucking sort that shit out instead of commenting them out.
I don't get it, if you're going to write tests, fucking test something with them, or we'd be better of without them.8 -

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.12 -

Yes! you made a difference.[image]
P.S.
started working at a startup as an intern(android app developer), Most of my work is like debugging the code, new feature implementations.
And the codebase is full of this kind of shit(even worse) plus literally zero documentation(not even for API's), not even a single line of comment in complete project(40K-50K), not any unit test/ UI test.
The funniest thing is when I ask for documentation he(boss | *) said: I am documentation.

Day of the interview sr. Architect says: "We have near 100% unit test coverage in our code."
One month later when I tell him there are 0 unit tests written against 300 projects: "Yeah, I knew that was a problem."
What can you do when the people who want to hire you lie outright to your face?
Oh yeah, and not a god damned one was written using any sense of object oriented programming at all. Every single damned project is written like its on a motherfucking punchcard put together by a cs 101 student with a 2 hour fucking deadline.
I can understand if it needs some work, just tell me. Don't fucking lie to me just to get me in the door to fix a problem you know you have. JUST HAVE SOME FUCKING RESPECT FOR YOUR CANDIDATES AND DON'T FUCKING LIE TO THEM!

I got some work on a new project so I ran the 500, or so, unit tests and it took almost 3 minutes. Everything was mocked and no external dependencies so I got curious as to how on earth they could take so long.
I found some suspicious code doing a while loop over a date range incrementing by 1 day each time. It turned out the tests didn't initialise the start date which defaults to 01/01/0001, and there are 5 scenarios!
I got test execution down to a respectful 10s.5 -

Working in the embedded systems industry for most of my life, I can tell you methodical testing by the software engineers is significantly lacking. Compared to the higher level language development with unit tests and etc, something i think the higher level abstracted industry actually hit out the of park successfully.
The culture around unit testing and testing in general is far superior in java and the rest.
Down here in embedded all too often I hear “well it worked on my setup... it worked at my desk”.. or Oh I forgot to test that part.. or I didn’t think that perticular value could get passed in... etc I’ve heard it all. Then I’ve also heard, you can’t do TTD or unit tests like high level on embedded... HORSESHIT!
You most definitely can! This book is a great book to prove a point or use as confirmation you are doing things correctly. My history with this book was I gonna as doing my own technique of unit testing based on my experience in the high level. Was it perfect no but I caught much more than if I hadn’t done the testing. THEN I found this book, and was like ohh cool I’m glad I’m on the right thought process because essentially what they were doing in the book is what I was doing just slightly less structured and missing a few things.
I’ve seen coworkers immediately think it’s impossible to utilize host testing .. wrong.
Come to find out most the of problems actually are related to lack of abstraction or for thought out into software system design by many lone wolf embedded developers.. either being alone, or not having to think about repercussions of writing direct register writes in application or creating 1500 line “main functions” because their perception is “main = application”. (Not everyone is like this) but it seems to be related to the EEs writing code ( they don’t know wha the CS knows) and CS writing over abstraction and won’t fit on Embedded... then you have CEs that either get both sides or don’t.. the ones to understand the low level need but also get high level concepts and pariadigms and adapt them to low level requirements BOOM those are the special folks.
ANYway..the book is great because it’s a great beginner book for those embedded folks who don’t understand what TDD is or Unit testing and think they can’t do it because they are embedded. So all they do is AdHoc testing on the fly no recording results no concluding data very quick spot check and done....
If your embedded software engineers say they can’t unit test or do TDD or anything other than AdHoc Testing...Throw the book at them and say you want the unit test results report by next week Friday and walk away.

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.)8 -
I fucking hate the fact that this group I'm side-hustling for gives maintainer access to every shitty dev they have.
Dev pushes four commits directly to master branch. Each time, pipeline fails on unit tests.
Shithead ignores failed tests and manually deploys to stage anyway.
Fuckface then declares (in group chat) that her "fix" works on stage and proceeds to merge to RC branch without updating the fucking unit test.
Pipeline fails (of course) and remains unfixed for the last EIGHT FUCKING HOURS.
This is what I woke up to at 6-fucking-AM in the god-damn morning.

I finally stopped being lazy and wrote 31 unit tests for my Discord bot.
Nothing is more satisfying than seeing them all pass and the GitHub workflow working without any problems. :)8 -

Me in the bus to Office
me: *press the stop button*
me: *see my Station driving pass me*
me: Sorry? I pressed that button?
bus Driver: Oh! You wanted to Exit?
me (thinking): no, this is a unit test and your unit just failed….
me: uhm, yes? thats why I pressed that button...5 -
I answered an robocall and all the robot said was "good bye". This must be the unit test of robocalls.6

I've been writing a complex mutation engine that dynamically modifies compiled C++ code. Now there's alot of assembly involved, but I got it to work. I finished off writing the last unit test before it was time to port it all to windows. I switched into a release build, ready to bask in the glory of it all. FUCKING GCC OPTIMIZATIONS BROKE EVERYTHING. I had been doing all my dev in debug mode and now some obscure optimization GCC does in release mode is causing a segfault...somewhere. Just when I thought I was done 😅5
-
Me: We really need to improve our unit test coverage.
Team/Boss: <sarcasm> Haha yeah.
Production Bug: I'm doing something nasty to a client, because a dev broke something but no test coverage.
Boss: How could we have prevented this?!1 -
My first new year resolution for this 2017 is learn to do the f****ng unit test before implement the code3
-
I guess I'm taking the piss.
I just spend half an hour wondering why a unit test failed; turns out all calculations were done correctly, just that -5 + 3 was being calculated and the test expected the solution to be -1.
Well, -5 + 3 does not equal -1 and I'm too stupid to add.
Half an hour. (-_- )2 -
Am I the only one who doesn't judge a programmers contributions by commits or change history?
Frequently I'm always near the bottom of contributors, because I don't make a million commits when it's broken. And I don't commit lines that will likely disappear in later commits. I like to finish a function, test it, check it, rework, and then make a "made function()" commit, as apposed to:
"Wrote function()"
"Wrote unit tests for function()"
"Fixed error"
"Code cleanup"
"Style guide compliance"
"Reworked function()"
etc.
Sorry that I keep my commit history clean and ensure it builds.7 -
Tired of reading spaghetti code written by your team mates?
Sit right next to them and ask them to write unit tests for that code.
Smash their head on the keyboard everytime they have to think longer than 10 seconds on how to test a specific logic.
Strangle them with any wire you find nearby till they agree to break up that spaghetti code unless they already started within that 10 second time frame.
When the exercise ends, tell them this is what refactoring is and ask them to pass on the knowledge.5 -
My whole team like to develop the backend of a very complicated platform in python because it is fast to develop. And host the front-end under nginx. And run everything on windows. And without unit test.3

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 -
I love Test-Driven Development!
And because of that fact, my heart shatters into thousands of pieces, when I recognize error events on our production nodes which are pointing onto a golden hammer function in a legacy project.
This particular function has about 300 lines with a bunch of subfunction calls and instantiations of helper-classes returning information for workflow.
Refactoring this code to apply proper unit-tests requires a way bigger investment than simply deal with 30 eventlogs a day, because this kind of payment is barely used by customers of our webshop.
This fact is a little itch each day of my work.
Guess it will make me go insane one day
¯\_(ツ)_/¯

LARAVEL MEME OF THE DAY
If 60> requests are sent in a short amount of time (and you have Laravel Passport installed) you will not receive an IlluminateResponse instance anymore; you will instead receive a slightly different SymfonyResponse.
Why? For the glory of Satan, of course.
If your code doesn't account for that undocumented garbage, your code will start throwing middle fingers here and there.
Tell me again the productivity joke with Laravel, I've just lost an hour and a half 'cause unit tests were failing and I had no idea why.6 -
How to NOT write unit tests:
A colleague of mine has developed a new package of software, many of our new projects are going to use. So in his presentation of the new functionalities he also showed us that he used unit tests to cover some of his code. So i asked him to show me that all tests passes.
He: I can show you, but one test suit will fail currently.
Me: Why?? You told us, everything is finished and works fine.
He: That's right, but they will fail because I'm currently not in the customer VPN.
Me: Excuse me, WHAT??
He: Yes, I'm not in the VPN that connects me to this one customers facility in Hungary, where the counterpart of the software is runnung live.
Me: YOU WROTE UNIT TESTS THAT TEST AGAINST A RUNNING LIVE FACILITY??
He: Yes, so I can check, that the telegramms I send are right. If I get back the right acknowledgement, the telegramm structure is right and my code is working.
Me: You know, that is not the porpose of unit tests? You know, that these test should run in any environment?
He: But they are proving, that my code is working. Everytime I change something I connect to the customer and let the tests run.
Me: ...
Despite the help of some other developers we could not convince him that this was not good and he should remove them. So now this package is used in 2 new projects and this test suit is still failing, everytime you execute all unit tests.7 -
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 -
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 🤦🏻♂️12 -
I just want to share this:
When I start working at my last job, I have little idea of what a unit test was.
My boss on one meeting said that unit testing will be mandatory (wich is ok and umderstandable).
Almost a *year* after that, no one still care about them. I see myself doing them the best I can, but I saw things like wrap the assertion line with "try / catch" to lie to the coverage and unit test percentage. Or in other cases directly uploading *manually* the code on the server without test at all.
And then, as the only developer who do the unit test ok I have to do the missing ones and repair the fake ones.
Then when something explodes the question all the managers love to ask "Did we had the testing?"
At least I quit... that job was some crazy shit, this is just one story of many.
Like that other time that my co-workers did not understand why I needed to do POJOs on an android app because the big bad JSON that the app used was working fine.... -
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'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. -
When you feel like your falling behind because at work you don't unit test, use dependency injection or pretty much anything the devs in the community discuss.2

Our best dev/arch just quit.
C dev lead & a dev staying late chatting.
Lead: am building, takes long
Dev: unit testing, time taking
Ask them y they r building on their latitudes when we got them linux precision with xeons/64gb workstation 1 each ?
Both: I code on latitude.
Build/test times. (pure Java/maven)
Latitudes=an hr or more
Precision=2m to 11m
Jenkins Infra we have =10 mins with test & push. Parallel builds support.
Am suposed to help with an open mind. They now want Mac pro12 -
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 -
Ugh all but one unit test is passing :-(. I know the code is working- so the problem must be in the test... [add @ignore to test]. Yay they all pass now!1
-
A designer pointed out that at a certain screen size (small tablet or large mobile), a menu was overflowing but had not yet collapsed into a toggle.
The manager comes to me and asks "why don't we have a unit test for that?"6 -
I'm getting really tired of those dumbass programmers that do not understand shit and then come to me when production breaks. (I am also a programmer, not really a DevOps engineer, but I'm the least worst at DevOps stuff, so it's my job...).
We're programming some kind of document management tool. Today we had a release, and one of the new features is to download all of your documents as a zip file, which is asynchronuously generated. When it's done, the user gets a mail with the download link to the zip file.
The feature works basically, but today it broke our production service, as somebody was running a test of it.
Turns out all the documents are loaded into memory to be zipped. So if you have 2 gigs of documents, a container with memory restrictions in that area will crash.
I asked the programmer who reported this «ops problem» to me, why he didn't just shit the files into a temp foler in order to zip them in there.
He told me that he wanted to do so, but did not know how to mock this for a unit test, and therefore went to the in-memory «solution», which was easier for him to mock.
For fuck's sake, unit tests and mocks are fucking tools, not ends in itself! I don't give a fuck about your pointless mocking code when the application crashes!
When I got to deal with such dumbasses, I'd prefer to mock those motherfuckers with a leaky bucket of liquid shit, which basically accomplishes the same task from my perspective: dripping shit all over the place and make everything suck as fuck.3 -
STOP WRITING CRAZY FUNCTIONS FULL OF INSTANTIATIONS THAT I NOR ANYONE WILL EVER BE ABLE TO WRITE UNIT TESTS FOR!!! STOP calling static factory methods that spawn up who knows what in mid function as if Im actually going to be able to mock such a dependency. Better yet, practice test driven development so we don't end up in this mess again11
-
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 -
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 -
If only they allow us to write unit test at work, its not that It is forbidden but we are not given time to do so :\
Done my test on my side project and now I can happily move to the next step.
Though I'd be happy if someone answers this:
1. When I have to execute functions by order, do I write all their code in one single function and divide them into regions (speaking of C# #reagion)
OR
2. I keep them split and implement the order attribute for XUnit?
My test case is basically just to make sure CRUD methods inside my repositories are working as expected, noting complex

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 -
During a period when devs had been told "The board has been promised that we are improving quality, so you must not do anything but write unit tests", I wrote a unit test that compares the number of system colors in .NET to a constant. It's still running today (a couple of years later).
-
We have started working on a new web based editor software. It already has 132 unit test after 3 months but can‘t do shit. In has no functionality, yet.^^3
-
Don't reuse your fixtures!
Each test case should be isolated. Don't ever think just because some function requires a similar input, it's safe to reuse it ALL OVER THE PLACE.
Why? Because someday, you want to change one functionality of one unit.
And you adapt your tests, fix your code, and suddenly, by changing one fixture, you break dozens if not hundreds of unrelated tests and now you have to clean up that mess.
It's even worse for functional tests with all those interwoven parts so that it becomes hard to reason about the scope of your tests when lacking proper documentation.
How I know? BECAUSE I AM CLEANING UP YOUR MESS RIGHT NOW!3 -
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!! -
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. -
Just found a unit test in a legacy project that is over 300 lines long, creates files on the server and multiple records in the database, then deletes them all. It takes over two minutes to run.
Madness5 -
Don't test complex functionality before production.. neither unit, nor system tests involved for my android app. Releaseing solely based on hope!2

I am learning about CI/CD and DevOps, and i finally made my first build/deploy/unit test script.
I use arch btw6 -
My boss: Write unit tests for this angular app
Also my boss: what do you mean it will take months to write the necessary mocks for our 177 specs
Also also my boss: why would you need to mock anything for a unit test
Also also also my boss: Just let each component import all the other real components, nevermind that that's an integration test and not a unit test8 -
Several days ago, I rant about how I stupidly "refactor" my code.
Now, it's solved. The code is now much cleaner and more maintainable...
The unit test works again. Perfectly...
I'm really happy for this, but I can't just tell it to my friends without explaining "what git and unittest is"
1 -
Before i found out about unit tests i'd create a console application where i'd test the functions
Good times -
If you're a "software engineer" with 10+ years of experience, but you've never written a unit test.... you're just a script kiddie with no right to call yourself a "software engineer".9
-
How fucking hard is it for people to learn what dependency injection is? "No, let me just initialize it inside this constructor because I've never heard of unit testing or SOLID". No matter how you try to provide them with a description, examples and tutorials, people still don't fucking get it because they've never actually programmed anything but this legacy crap for the past 10 years where every test is a functional one that goes through a million lines of code in a single test case. Good thing I have hours to spend every day when I want to run some tests.7
-
The way I was told to write unit tests was particularly terrible.
No mocking of objects or dependencies so the tests ran the actual code in full including updating databases and files. Then at the end of each test there was code to restore all changes back to before the test.
Each test ended up being over 100 lines. Madness.1 -
Unit test works, unit test works... commit it, push it, take screenshot of it, and go to sleep... peacefully...

Today I present to you:
Declarative unit testing!
Instead of writing a bunch of example usages of your code, just define the behaviour you expect it to have!
To test a Fibonacci function, instead of writing
assert fib(1) == 1
assert fib(2) == 1
assert fib(3) == 2
assert fib(7) == 13
assert fib(69420) == 576441346790001
You write instead:
def test_fib(n):
if n <= 2: return 1
return fib(n -1) + fib(n - 2)
Simple! Can't possibly go wrong! All your tests will pass instantly!11 -
Fucking fuck sonarcloud and everything about it. Part of the build pipeline for us to deploy code is to ensure that 90% of the code is covered by a unit test. Great in theory, horrible in practice. You think you've written enough tests that actually add value and test a valid piece of functionality but NO, sonarcloud throws a fucking fit because you're at 89.888 then your branch is going nowhere. Because everyone else gets to this stage and writes just enough tests to get the coverage to 90.01% then it becomes a stand off of who will break first; the code coverage threshold or your mental state.4
-
you know, i really enforce unit testing. i like having a good coverage, and such.
one might say it costs a lot of time, but its really worth it, we come out pretty clean.
theres only ONE thing that REALLY costs my time: explaining to some newcomer unit-test hotshots why they should not overdo it so much. they come, show me some goddamn blogs where this and that is injected, and start injecting and de-coupling my fucking domain model to a point where they test god-fuck know what but not the actual productive code..
so listen in DDD, we inject to
- service layer
- domain services
- repositories
- and factories
we DONT inject every dependency to every single domain object, they ARE newable and have no dependencies to other domain objects PER DEFINITION, except via model
(and aggregates via root)
my theory, they fuck around with that tests because they dont actually know WHAT to PROGRAM... so STOP FUCKING AROUND, and WRITE YOUR CODE, and refine the requirement if you dont know what it should actually do3 -
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 -
Guys...
It has come this far...
I... I like test driven development and the amount of unit tests and security it gives you. And I kinda laugh at people that don't take unit testing seriously :p35 -
I am usually lurking in here since I never really worked as a Software Developer, but until I start going to the University, I thought I might also find myself a job in Software Development.
Well... I don't know where to start.
Someone in here heard of JBoss? Me neither... we're using it... It is a Framework to deploy fortified Java Web Applications. My first day was very chaotic and was dedicated to get this fucking shit to work. I got JBoss 7.5 from my colleagues and started deploying the hello world program...
So. Many. Things. Gone. Wrong...
After like 5 hours of troubleshooting, I had to install/setup a new wrapper with my own batch scripts, install SPECIFICALLY jdk 1.7_17 (anything else won't work) and downgrade JBoss to 7.2.
Yeah that's the first thing. Let's continue about JBoss. Version 7.2 uh? What's the newest one though? Oh it's now known as WildFly... huh... FUCKING HELL, THE NEWEST ONE IS VERSION 10.1??? AND EVEN 10.1 IS 1 YEAR OLD? WHAT THE FUCKING FUCKK AAAAAAHH...
So yeah, after that, without any expectation, I had a look at our codebase. Unit tests huh? I couldn't find a single self written one to test the applications functions... I asked my fellow devs and they told me that "it is too time consuming and we have to focus on new features, the QM Team will just manually test the application". Ever heard this bullshit? A big fat ass codebase with shittons of customers and not a single unit test...
So last but not least, since it is a web application, it also got a site. Y'know RichFaces? The deprecated front end library for Java Webpages? Where you got like 150 Tables per page everyone with a random id everytime you reload? Yeah I don't think I have to explain that to you guys...
So now YOU tell me? Is this a place to be 😂😂😂6 -
FUCK YOU WORDPRESS wtffff with that shit , i can't use multisite if running in 8081 port ?, fuck you! your """ cli """, your media folder with that month and year stupid subfolders, your plugins and your fucking unit test running on a complete WP instance. GO FUCK YOURSELF! stop with that shit and remake all that shit.7

"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."

A newly joined developer (who was supposed to be very senior) comes and asks me how to write a test cos for some reason the person didn't know how to mock.
In Java,
(same for any other implementation which has an interface)
Writes Arraylist list =.....
Instead of List list = Arraylist...
Deployed code (another engineer from another country helped to deploy since this new senior dev didn't have access yet.
But the new senior dev didn't update relevant files in production code which brought down the site for nearly an hour. Mistake aside, the first reaction from this new senior dev is 'WHY DIDN'T THE DEV THAT WAS HELPING DIDN'T DO THE FILE UPDATE?'
This was followed by some other complaints such as our branching stragies are wrong. When in fact the new senior dev made a mistake by just making assumptions on our git branching strategies and we already advised on correct process.
Out of all these, guess this is the best part. The senior dev never tested code locally! Just wrote code, unit test and send to QA and somehow the test passed through. I learnt this when I realised this dev... has not even set up the local environment yet.
I keep saying new but this Senior dev been around like 3 months! This person is in another team within our larger team but shares same code base. I am puzzled how do you not set up your environment for 3 months. Don't you ask for help if you are stuck? I am pretty sure the env is still not setup.
Am I over reacting or is this one disgusting developer who doesn't even qualify for an intern let alone a senior dev? It's so revolting I can't even bring myself to offer help.9 -
I was wondering why my tutor needs a whole ass week to accept my MR.
Today he rejected one, so I got a chance to look at whatever he's doing.
He's checking line by line every single test I make and creates a variable for each dumb thing.
𝘦𝘹𝘱𝘦𝘤𝘵(𝘴𝘰𝘮𝘦𝘵𝘩𝘪𝘯𝘨.𝘪𝘥).𝘵𝘰𝘚𝘵𝘳𝘪𝘤𝘵𝘌𝘲𝘶𝘢𝘭(𝘴𝘰𝘮𝘦𝘖𝘵𝘩𝘦𝘳𝘛𝘩𝘪𝘯𝘨.𝘪𝘥)? No, this is bullshit.

𝘤𝘰𝘯𝘴𝘵 𝘴𝘰𝘮𝘦𝘖𝘵𝘩𝘦𝘳𝘛𝘩𝘪𝘯𝘨.𝘪𝘥 = 𝘴𝘰𝘮𝘦𝘖𝘵𝘩𝘦𝘳𝘛𝘩𝘪𝘯𝘨.𝘪𝘥
𝘦𝘹𝘱𝘦𝘤𝘵(𝘴𝘰𝘮𝘦𝘵𝘩𝘪𝘯𝘨𝘐𝘋).𝘵𝘰𝘚𝘵𝘳𝘪𝘤𝘵𝘌𝘲𝘶𝘢𝘭(𝘴𝘰𝘮𝘦𝘖𝘵𝘩𝘦𝘳𝘛𝘩𝘪𝘯𝘨𝘐𝘋)
I don't even know why you would take a week to accept a merge request when all you're doing is creating variables for things you use only once. I'm not even mad, I'm not ranting, I just need to know why would you do such a thing17 -
I've got staff, I've got staff
And they bill time and a half;
Now I only write the gist you see
And they can code the rest
Open source, Fraying nerves
Smoothing out regression curves;
Try this framework, it's ambitious
It was made of spit and wishes.
Coffee rings, at first glance
But of course miss, he's freelance;
And this code base is a truly scary mess
I can't expand the menu
Even chance its home brew, unit test;
Unit test, unit test!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...
-
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 -
We basically don't unit test at work. I write some tests for my code and honest to God people complain I'm wasting time saying a test bed and manual tests are good enough. We don't write test beds for about half of our production code and rely on integration tests for the rest. We only test release builds which have been symbol stripped, I get handed a crash report with no stack trace that I'm unable to reproduce and expected to stay late to fix it for some arbitrary internal deadline.
I've since moved to R&D where basically I'm left to do my own thing so it's better.
We don't project manage. Project leads take time estimates and double them so management might cut them some slack. This doesn't matter because management made up time estimates before the project started. Last project I was on had a timeline of 3 months and took a year.
We have released broken products. Not that any of the above really matters, our software products have made about 50k revenue in 2 years. There are 6 people on software. Fortunately hardware has made about 3 mill. That said our hardware customers are getting frustrated with us as we keep fucking up, shipping broken products and missing deadlines.
I've been working there about a year and a half and will be looking for a job at the end of the current project.
I joined devRant about when I was most pissed off with my job, my rant frequency has definitely gone down since I moved over to R&D. -
Fixing unit-tests that expects 2017... kills my motivation at first workday this year.... I hate my coworker -..-

I feel really dumb for not understanding this but somehow my brain refuses to make sense of it. Using mocks in unit tests that read like this:
Mock: 1 + 1 = 3
Assert: Is 1 + 1 equals to 3?
Or when testing an API and mocking the response to "something" and then testing if it returns "something". I don't get it. I just don't. What did you test? Your typing skills? Your sanity? When does it fail? How is it a test when even if I intentionally break the actual code you are writing the tests for, it still returns "successful" because you kind of programmed it that way?
Call me an idiot but I've been reading about this for a long time now. I see examples online where mocking makes sense and it actually helps test the code but this kind of writing doesn't make sense to me. Some enlightenment would be appreciated.6 -
"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 -
I'm a strong believer in the triple-A unit-test pattern: Arrange, Act and Assert
Anyone else that uses this for their tests? Do you see any cons to using this approach to writing tests? Are you using an alternative?11 -
Ngl, I'd probably become one of those guys that tries to port DOOM onto things, or maybe maintain some old repos. Maybe fuck around and actually write a unit test idk1
-
Are there people here who actually unit/integration/end-to-end/stress test (almost) everything? Or is it a common fact that nobody has time/budget and/or needs to do so?
I like to think I test all the code I write, but to be honest, I think it's closer to 1 to 5%4 -
this really happened:
Interface Team Lead: "hey I want any time deployments and better QA"
Me: "ok sure. I have CI/CD, but yiu need to work in feature branches / tags, and make sure your code passes automated builds and unit tests"
Team Lead: "I dont have time to test it makes me unproductive! and creating a branch is an extra step which is going to set me back. Im telling the boss you are impacting performance!"
Me: "you want better deployments and QA, but you can even create a branch or tes your work?"
Team Lead: "We have deadlines!" -

Been working at this place for years and I've never seen our platform's tests fully green. There is always some test case broken or configuration wrong. The test, not the application code. In very rare cases it's actually a bug.
So sure! Let's fix tests on a daily basis because some morons do not understand how to write unit tests! Majority of the actual tests are end-to-end tests that take hours to run. And they fail because some data was wrong in the database, or an environment variable was wrong, or my favorite one: it only works between 10AM and 3PM because that's business hours and you can't execute this piece of code outside of it. I would like to slap some people who say that this is fine.2 -
Today, I fixed a dodgy unit test by stopping time.
(I overrode the time() method to always give the same result) -
That feeling when your newly added calculation module now has 93% code coverage in unit tests, with the client working on a test case for the last bit.2

When I'm stuck at something and can't think of a way to solve it, I just keep running the unit tests and stare at the screen. And then youtube. And then I feel terrible.1

tests? ain't nobody got time foh dat. my brain already does all the job. it assumes and says to myself "all tests passed ✅" whenever i make quick changes
i like to live dangerously 😂1 -
Whenever anyone asks me why I dislike C++ I'm just going to point to this current app I'm working. Had a unit test with an extern method declaration that had 7 or 8 different parameters. No big. Problem is that the ACTUAL definition of the method had 1 less parameter than the extern declaration. It worked perfectly fine in x86. Ported to x64, compiled fine, hard crash at runtime. Debugger not a super lot of help. Took me a couple days to figure that one out. Also I am broke so I can't even drink the pain away. Neat.

This is just a sweet little harmless block of code, why should I unit test it?
3 months later...
Bug in production : This is why. -
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 -
Finally made my node production server stable enough that I could focus on writing tests*. I start by setting up docker, mocking cognito, preparing the database and everything. Reading up on Node test suites and following a short tut to set up my first unit test. Didn't go smoothly, but it's local and there are no deadlines so who cares. 4 days later, first assert.equal(1+1, 2) passes and I'm happy.
I start writing all sorts of tests, installing everything required into "devDependancies," and getting the joy of having some tests pass on first try with all asserts set up, feels good!
I decide to make a small update to production, so I add a test, run and see it fail, implement the feature, re-run and, it passes!
I push the feature to develop, test it, and it works as intended. Merge that to master and subsequently to one of my ec2 production servers**, and lo and behold, production server is on a bootloop claiming it "Cannot find module `graphql`". But how? I didn't change any production dependencies, and my package lock json is committed so wth?
I google the issue, but can't find anything relevant. The only thing that I could guess was that some dependencies (including graphql) were referenced*** in both, prod and dev, and were omitted when installed on a prod NODE_ENV, but googling that specific issue yielded no results, and I would have thought npm would be clever enough to see that and would always install those dependencies (spoiler: it didn't for me).
With reduced production capacity (having one server down) I decided to npm uninstall all dev dependencies anyway and see what happens. Aaaaand it works.....
So now I have a working production server, but broken local tests, and I'm not sure why npm is behaving like this...
* Yes I see the irony.
** No staging because $$$, also this is a personal project.
*** I am not directly referencing the same thing twice, it's probably a subdependency somewhere.2 -
So you're working on a product that basically the main thing it does is fire off http requests and parse their responses into a nice model. We've made some nice helper class that allows you to do this easily, but a simple piece of functionality is not in there yet.
You agree to add this one simple function and decide to:
- Not conform to coding standards set by the team
- Document its behavior which does NOT match the implementation
- Not write a single fucking unit test to prove it's functionality

I had an interesting mystery the other day. I work in the UK, but I'm working remotely from the US for a while. First day, I made some changes, ran the tests and they failed. Weird part was the failing test was for a component I hadn't touched. I took a closer look, and realized it was a date off by several hours. The test was checking that a passed in date appears in the output. But it was creating the date by parsing a string. The library I was using defaults to local time, but the component uses UTC. So, I had inadvertently created a unit test that only passes when run from UTC. But I had never noticed before because my work is in that timezone. Yikes!

Seriously though, since so many devs I know rant about their QA / test engineers, what would your ideal Test engineer look like?!

Me: What if there are changes to the code in future?
Dev: We'll manually retest the implementation. It'll be fine.

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 -
I got assigned to work on a new project a couple of weeks ago. We got the POC code handed off from senior management, since he came up with the idea over the weekend. The project concept is hella exciting, but the dev manager and PO I have to deal with make life unbearable to say the least.
We have only 2 devs (including me) and 1 QA on this supposedly very important project. Of course, management announced the project to the clients already, so now we have to deliver ASAP cause it adds “sizzle”.
The MVP deadline is... no one knows when, either July 30th or September 1st. The MVP requirements are... unknown. I swear if someone saw the list of tasks and issues attached to “MVP” Epic, they would call us nuts trying to fit it all in.
To make things better, each PR requires 2 reviewers, so we end up adding manager as a reviewer just cause we need him to hit that “approve” button. So in attempt to make life easier, we requested to have a third developer. We are getting another developer, but that guy doesn’t know how to unit test a pure function...
Current priorities are... unit testing with coverage of 95% and if we want to refactor code, we have to add area to the list in a Google Doc. As a result, we are not tackling big things like risk of SQL injections not to mention big features like i18n (5-6 languages to support by the way and yes, it’s part of MVP as well as SSR no one knows why). Currently, I spend 2-3 hours a week in calls with the team just to figure out what the hell MVP is, what we have to do and why we have to do it. Last time we spent an hour refining 1 spike and breaking down one story into 3.
Oh, we also don’t have a deployment plan, not even to test environments since DevOps team was not aware of this project at all. Thus, QA cannot create any test suites and have to test everything manually which eats a lot of their time.
This whole project is a big hot mess and I’m considering leaving it all together especially since I’m working on two squads at the same time. I love the project, I love the idea, but management makes it unbearable, so I’m not even motivated to work on that.5 -
If your unit test has a bunch of mocked up dependencies which you puppet to do whatever the fuck you want. Something could be improved perhaps
- write a test at a lower level if possible where the dependencies can be abstracted away, or you pass down what you need from them
- write a higher level integration test, i.e. which uses real spring context instead of mock dependencies
But my senior tells me that a unit test will almost always mock all of its dependencies, it should only test the logic in it's tiny atomic piece of work. Mock everythign else out.
Devrant, how do you unit test? I'm looking to learn more on the topic and hear how others do it.5 -
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 -
I recently started to use automated tests for everything and it is really great to not worry about every little change anymore.
But I think I'm not very good at it. The tests themselves are quite slow and I'm not sure if I'm covering everything the right way. Also, I'm very slow at writing the test cases.
SO I want to learn more about it. Do you have any recommended books on this topic? Anything about unit or feature tests and TDD, language specific (PHP) or general is appreciated -
Delete data because it's corrupt. Angry call from support that their data is gone but they've managed to recovered it. Try to explain why it was removed only to get told they need that data. Fine whatever but if I see any more bug reports about that unit I'm not solving them because it's the data not the code. This is why I wish they'd test on their own databases, which they have, but somehow don't use.
-
And here I am again, reading test cases that basically boil down to:
$testCase->foo = "bar";
$this->assertEquals($testCase, "bar");
$testCase2->foo = null;
$this->assertNull($testCase2->foo);
Why would anyone feel the need to write these kind of tests? They don't do anything. If I set up my mock a certain way, of course I will have that data, esp. if the unit under test only applies the data AS IS. (Funily enough through another component that already has the relevant dummy tests in place making these tests extra redundant and obsolete.)
You would think that one test case with dummy data suffices, yet no, there are like 30 examples that lie to you about apparent business logic cases, yet in the end the way you set up the mock decides what you will or won't get.
What's the point?8 -
Programming is like getting a crush.
When you couldn't turn her on, you never figure out why.
Even if you did it, you still cannot believe why it could succeed all in a sudden.
The first time you did a unit test
is when you asked if she is okay
for a date; step by step,
In order not to break.
First, ask if she is free; Then, if she really need to eat,
she said OK there.
But, finally she didn't turn up
Integration test failed.
She was such a bitch. -
I just wondered... Is it even possible to write unit tests for an OS kernel or a bootloader?
How would you do that?2 -
Today I read a great article on mutation tests, how to use and why they are important. It looks like a great thing, but...
I have never wrote any unit test in any of my jobs. Nobody in my workplace does that. And now it seems like 100% test coverage is not enough (I remind you, that I have 0%), they all should mutate to check if the quality of unit tests is high.
It seems that I'm left behind. I played with tests in my free time, but it seems the more you write them, the better you get at it, so I should be writing them in my job, where I code most of my time. Not only that, of course, I would also want to ensure that what I'm working on is bug-free.
Still, it will be impossible to introduce unit tests to my project, because they are novelty to the whole team and our deadlines are tight. The other thing is, we are supposed to write minimum viable product, as it is a demo for a client, and every line of code matters. Some might say that we are delusional that after we finish demo we will make things the right way.
Did any one of you have a situation like this? How did you change your boss and team's mind?8 -
Trying to convince the class that test-driven development + DTSTTMPW ("do the simplest thing that might possibly work") + pair programming is the way to go, our software dev prof had us split in groups of two that would each get a turn to
1. add a unit test
2. edit the code so it passes the test
3. commit the change
The goal was to write a java class that converts integers to roman numerals.
Each group had only 2 minutes before the prof made them revert their changes.
After 45 minutes the code was just 10 lines of this:
if ( n == 1 )
return "I";
else if ( n == 2 )
return "II";
else if ( n == 3 ) ... -

Mini witch hunt going on with broken builds last couple of weeks. Change satellite assembly/project A, breaks random unit test that hasn’t been changed for months and the TFS nazi sends out emails demanding the “broken” projects be fixed. Doesn’t matter the unit/integration tests are likely out dated and team responsible for the tests needs to fix it.
Yesterday I deleted some logging code out of a security assembly, broke an integration test that hasn’t needed to be ran since January (test database didn’t exist anymore).
I would have had to re-create the database, re-import the test data (not trivial), re-deploy a service using the test database…blah. All because I removed some logging code.
I deleted the gated check-in TFS build definition. Code check in … no sirens …whew! I win! -
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 -
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.

This one time I was working for an investment bank and my manager tells me unit tests are good to have feature and we can descope those to meet the deadlines.
What next meeting the acceptance criteria becomes good to Have or delivering the product becomes good to have? -
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 -
I build a website based on express js.
I want to create some unit-test for my web-pages.
It is always possible to use `http` package, send a "mocked" request, get the result, and perform some regex.
The problem is:
1. How can I maintain session?
2. Is it even necessary?
When it comes to web development, I have no idea about TDD best (and easy) practice :(5 -
My brain hurts from trying to figure out this unit testing crap. Is it just me or is it really a struggle to test your front-end code? I'm using jest and enzyme to test our React app but complicated parts of code with multiple state changes or calling props is making my life a living hell. I mean I usually just debug by console logging everything and it works lol...but my fucking boss has forced me into writing this unit testing crap. FML.8
-
God dammit, I hate my bloody coworker sometimes. He's doing a huge refactor, and committing... which is fine, but he's clearly NEVER run the fucking test suite. I didn't write that much coverage so you could commit something that breaks the build and then fuck off to lunch.
Not only has he not run the test suite, I don't think he's run his changes AT ALL. The bloody modules don't even import the way he's written it now.2 -
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 -
Goals for 2018
- Add E2E test or unit tests to my projects
- learn a new (programming language) perhaps Go, or Rust
Better have a few than too many2 -
Spent a whole morning trying to make a unit test work only to find out it didn't work because of duplicated code.... Fml
-
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..... -
Who I hate:
People who put their tasks to ready for (integration) test without even once running it against real services and the actual database instead just the mocks of the unit tests.
=> I want to test business logic, not fix your internal server errors... -
Oi, typescript, why do you take 15 seconds to transpile my project!?
It's a waiting game for the unit test to even start :/4 -
I'm really bad with unit tests
I feel a bit embarassed about it especially cause I do this professionally but I really don't know what to do about it. I thought it would be helpful if I checked out some examples by others but they mostly seem like "self fulfilling tests" and I fail to see their purpose. There have been few instances where I thought a test would make sense. I feel like I have writers block whenever I try to write unit tests and learning by doing doesn't seem to help me much.
Do you have suggestions on how I could get better with unit tests?11 -
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. -
We have an unit test that tests the average of a sequence of numbers generated randomly using a gaussian distribution. Of course it fails from time to time, it's random! Failing to fail, would mean that the generator is not generating random numbers, therefore failure means success, but success does not mean failure.
Wait, why did we add this test in the first place? -
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? -
Only when the latest feature is implemented, the last bugfix and the last workaround are found, the last unit test is written, the latest CI/CD pipeline done, the customer guy does manual testing and acceptance tests on the staging server and let's them pass and a few days later it's pushed to production...
You will be reminded (again) that shitty customers do exist! A customer is the least capable person to tell you what the customer actually wants and is also the least trustworthy person to test the features he requested...
Holy fuck come on! Just test that shit on the staging Server! One Look could have already shown you that that's Not what you expected!
I checked the logs after that and yup you guessed correctly... The said endpoints weren't even used on staging, only on production...1 -
Not learning to unit test as I was embarrassed that'd I'd missed it in college.
Now, thanks to a great ruby module I've taken this year, I'm leaning towards TDD. I really enjoy it. -

do you know the feeling, when it is friday and it is like nice hot weather 26°c. you kinda wished you could just zit outside and enjoy the view days of the summer that are not to hot or to cold (location: the netherlands).
this made me slack off today. only did my sprint planning for next monday and wrote some unit test and some software modification documents.4 -
I hate deploying this project, it's just nerve wracking. I started it when I was a newbie to web stuff so I didn't know shit. Now it's just a big project with no unit tests, I test it all by hand.
It looks professional though, but the underlying code is just a mess.5 -
When you don't know how to write test:

What do you guys use to write unit tests in C? I look at some libs such as check, cmocka, gtest etc, but they all seem like way more than I need. Also, I have a hard time to separate test files and source code files (directory structure wise).
Any recommendations?5 -
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 -
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? ^^ -
Need help in Unit Tests,
I've reached a point where tests randomly fail, but if I run that test alone it never failed.
I do have lots of shared data between test functions of the same test class.
What options do I have?
1. Make each function responsible of seeding data into InMemory database?
2. ??? (I don't know what else I can do)
Any help is great :)18 -
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. Do any of you have any experience with the available unit testing frameworks? In the past I only used Karma and Jasmine for Angular unit testing.2
-
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 -
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 -
I really need help. We are doing some interface files, something like C header files and configurations.
Management is aware of the "unittesting" buzz words and expects me to write unit tests on "header" and configuration files....
I tried to explain that there are no units to be tested, asked which units should be tested but in the end....
What does it actually mean to test definitions of structures, classes and methods?!3 -
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. -
We had a bug with our Karma test (JavaScript unit tests). The headless Chromium crashed after test 272 or 273, every time since a week. I fixed it, but I even don’t now, we Chromium crashed 🤷🏼♂️

If you compare a software developer's job with another, let's say a doctor or a lawyer, the former doesn't require mastery and there is continuous chase on fast changing version numbers or an entire platform coming out. Former innovates without question and gets burned out in the process. While the latter demands mastery of certain fields and the specialization isn't diverse enough compared to former. Yet the pay for latter might be higher. What are the pros and cons have you felt as a developer and how do you cope to address it internally? Is it just the thrill and excitement of new things coming out? What fulfillment do we get aside from the satisfaction of clean code, unit test and successful deployments? How much impact have we really given? And is there a place for developers to final settle down? Don't get me wrong; I won't stop until death probably but I hope adulting responsibilites won't make us break.

Creating unit test files, but being to lazy to write the actual tests and then giving up creating the files as well.

I attended an interview, the guy gave me a problem to code with unit test. I cracked it, he seem quite happy with my work.
However he send me some questions to solve at home... I don’t understand the point of this 😣
So sad to see people are becoming zombies n just follow the process instead of thinking logically!!! 😮3 -
Just spend two fucking days debugging a few methods in our program. I used unit tests to call those methods (don't want to navigate through the complete program workflow)...
Yeah, guess what: the test cleanup includes a fucking rollback transaction function. So NONE NADA ZERO FUCKING CHANGES WILL BE PERSISTED. Fuck me3 -
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 😅 -

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 -
That kind of devs that creat unit test for a method never used in code instead of deleting it. #CoverageGoals

I really hate how steep the learning curve is for testing. I've been writing the same test for a week for a 150 line directive, and it's driving me fucking nuts. Nothing makes sense. No one in the office to help me. Only 10% of engineers here write any tests. I don't know what to do. Overnight they made it a rule that if you want to move up to the next level for software engineers, 80% of your code needs to have unit test coverage. It's just bullshit.4

Today I created some reusable clean decent code to replace the random chaos in a huge project and then realised I had 3 options:
1. Sort out every instance to use the new code. This is very high risk because the project is both a shit show and has no tests. I don't have time to manual test or write unit tests on so much stuff.
2. Move over only some so that I can manually test. Still no time to unit test (management is fucked on their priorities). This will fuck the project even more since i will never get time to revisit this and adds yet more inconsistency and chaos to a project on its last legs and has this problem in droves.
3. Leave the project fucked

I'm veering towards option 3 these days.1 -
I was writing a bash script for about two days to have a decent way to create tags with a specific convention and everything else should be escaped. After repeating to execute the script with around thousand different parameter styles for hours a developer buddy asked me why I'm not writing another bash script which acts like a unit test to execute the script with those many parameter options...
We never saw that developer again since that day. -
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? -

2nd week at my first job after I got my papers and what am I doing?
Background:
I followed a course of three years where all we learnt was web development with php and javascript. I of course wanted more and spend hours after school learning as much as a could without any help from others.
About the course:
We learn to tinker with code (php, javascript).
There was never a mention of design patterns.
We never got to know about TDD (test driven development).
Now:
Got the papers, found a job as a c# junior development and am currently working on a C# .NET web app using azure cloud and high standards using unit tests to provide a product for the awesome company I work at which should generate a stable income.
Tldr;
Hard work pays off. -

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 -
Today checked my learning time tracker. I have spent already 80 hours for learning angularjs. And I still am not able to write unit test without errors. What the fuck. How many hours more do I need to finnaly be able to write unit tests without any problem?
Like today getting
An error was thrown in afterAll\nSyntaxError: Unexpected token 'export'
and I do not even use afterAll() funciton so they give error somewhere from the inside of libraries. Why they do that? why cannto they give easy to understand error?
Everytime I sit to write unit test for learning, all the time I feel I will not understand. And I am right everytime. Damn. That makes me need to force motivate myself. I want to see results, not sit at the same place so many time.18 -

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 -
The CloudWatch API is an awkward piece of shit.
No convenient way to just ask for the latest value of a metric. Gotta supply a time window and hope metrics were actually reported within that window.
Oh and make sure your timestamps are in ISO 8601 or the request will fail (but the SDK does zero validation so a unit test won’t catch it of course).
Oh and you have to assign an arbitrary ID to each metric query in your request even if you don’t care about mapping the results back to the queries. And the regex for the ID is just fussy enough to be mildly irritating.1 -
I used to hate the tediousness of "busy work" e.g. changing labels in forms or running unit test procedures. But damn does it make the day go by quicker. I missed having something (anything) to do.

I got some problem. I work on some company maintaining web application. Every time I add some feature I often accidentally break other features. I read about testing (unit test, integration testing, etc) and ask my project manager and CTO to implement test on our web application but they refused it. The reason is because the web application is already large and it will take a long time to implement. Actually maintain this application is very stressful because it takes along time to add new feature and every time I break something either CEO or Client will scold me. Do you guys have idea/solution to solve this problem?1

Writing unit tests for singletons...
I would just want to refactor it so it’d be easier to unit test, but need to write unit tests in order to be allowed to refactor. Geez...3 -
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 -
When you do some group programming and let yourself get led wasting an entire day into writing 6 out of ~12 tedious higher level unit tests with lots of data setup and jerry rigging, that turn out to not even test the code changes you made on a ticket that another team is depending on.
But thank you to your tech lead for helping rope you out of that stupid shit with knowledge and clout.
Unfortunately the ticket has your name on it and everybody except the goon squad probably thinks you're a retard for going down that adventure (which was not your idea or desire).
I need to learn how to articulate no this isn't worth it, the complicated monolith software architecture with many different moving parts, among many other things. -
2 weeks+ ago I made a PR into our codebase containing sample refactor that streamlined a significant portion of code. Also, I did refactor only on two handler packages (for MVC folks, that's Controller) as proof of concept, to figure out how convinient / logical the part would be for everyone.
We have rule of 2 approvals for merge (for 5 team members)
While writing refactor, it obviously blown up a lot of unit tests, but still coverage was fairly poor (that stuff was rushed, there was back than no time for unit tests). After my refactor I spent couple of days writing tests that hit fairly sweet (comparatively) coverage. (I managed to bump coverage from low 20s to high 80s, and have less code for tests)
I got first approve pretty much immidietely, other team member was on vacations, and 2 of them forgot.
We generally try to close PRs fairly quickly (usually same day kind of deal), but that one was just.. hanging in there. So I pinged everyone to re-check it to greenlight it but of course, loo and behold, merge conflicts arised. I ended up fixing actual logic (just some method signatures changed, not a big deal) and ran the units.
So, one of that handlers got quite a few of edits, and guess who is pretty much rewriting unit tests for second time now...
Dude, sometimes I question why tf I even bother with these tests... Feels like sabotaging my productivity, especially with bullshit like that4 -
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 -
Management wants me to write e2e tests instead of unit tests. The problem is there are e2e but not a single unit test... I plan on refusing.

I have been writing unit test cases after writing the code. Not the other way around. I do not think this is TDD . Is it ATDD?
Should I keep going on with this?
Thoughts?8 -
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 ?) -
Audience question to Uncle Bob: Which parts of the code do you unit test? What about code coverage?
Uncle Bob: Well (chuckling).. You test the parts of the code that you want to work. -
Is unit test helpful in React web app? Why do I think it is just wasting of time? How often do you use unit test in your web app development?12
