Two unit tests, no integration tests.

all unit tests passing

My morning:

Me: Why did you just delete the failing unit tests?

Intern: I debugged it for a while and found one of the other developers broke it with his recent changes. I couldn't fix it.

Me: Did you let him know he broke it?

Intern: No.

Me: So you just deleted it and decided to pretend the feature isn't broken?

Intern: ... No ... I mean ... well you told us yesterday we needed to have all the tests passing.

(I NEED a stress ball people)

This passes all unit tests

Unit testing be like "all tests passed"

Working with a team of interns, pointed out a bunch of unit tests are failing, they said they would take care of it.

10 mins later they opened a pull request to delete the tests that were failing.

fml, fml, fml, fml ... and ... oh yeah fml

Fuxk yeah! My code works! It's 2AM, I'm happy and there's no one around, so I wrote a poem :-P

What was once impossible,
Is now close to completion,
Thanks to my debug statements,
Which now await their deletion.

When your colleagues have no tests for their code and tell you not to touch it, because it WORKS!

2 unit tests. 0 integration tests.

When you write 2 unit tests and no integration tests.

Automatically generate unit tests for all the code I write.

I think my automated test texts me more often than my boyfriend does

About 11 months I posted that my wife was pregnant. I now have upgraded to son 1.0. All without writing any tests!

software developers and testers be like

The past 2 years where I work:

Me: hey let's use git instead of ftp!
Boss: should we?
Some time later: he is loving it...

Me: hey let's use trello instead of excell!!??!
Boss: huumm.. Dunno... Should we?
After much convincing: whole departments are using and loving it....

Me: hey let's move from rackspace to DO!
Boss: huumm... Convince me...
Year latter: everything smooth and muuuch lower prices... Managing 6 servers instead of one...

Me: UNIT TESTS!!!
Boss: nah, this but a waste of time...

For real? Get a grip man, I only encourage solutions tested ( no pun intended, or is it ) by me for a long time...

So what does everyone think about unit tests, do you do it?

My own experience is I've seen people on my current team disable failing tests...

And for tests: 404

"Can you work on this ticket? It's kind of urgent."

-- "OK"

"And could you please not refactor? Just get this done."

-- "Why? What's the issue?"

"The logic is complex. We should not break it."

-- "Erm, that's what the tests are for. So yes, if the need arises, I'll refactor. The tests are my guidelines if the logic breaks or not."

There's a reason we create tests. So let's not hinder code base improvements by some random fear that stuff might break.

If breaks due to refactoring, we'll fix it by adding a valid test case during and then fixing the bug.

If my refactoring does not break the tests, I'll assume the code base is stable.

If your code is untested, then we have a complete different problem.

integration tests...

When your colleague is having the time of his life writing unit tests

Once I applied for a Java position and they sent me a a online test, user and password. When I first tried to log in, it gave me an java exception. I lost hours trying to figure out the exception , thinking it was the test :/

How to quit smoking as a developer, tutorial:
#1: You're only allowed to smoke when every unit test is passing.
#2: ???
#3: Profit

Not writing tests.

Yes we exist.

Unit testing be like "all tests passed"

Only write unit tests. It will be fine.

Made me a little debugging duck out of post-it while waiting for my program to finish testing

People who try to justify not writing unit tests are the same as those who try to justify not using a condom.

You'll be sorry later.

Me: This is good, but here’s a small tiny change that will make it even better!
Tests: 1 success, 3628 failures, simulator freezes and crashes computer
Me: never mind...

"Trinidad And Tobago" changed their country name to "Trinidad & Tobago", and the .Net framework reflected that change.
So that's why this unit test is failing.

I GUESS BULLSHIT IS NOW INTERNATIONAL.

This is my life now...

QA trying to break my code

Teaching myself to write unit tests that actually have value.

You know how some people put those little badges in their readme files in GitHub?

Well, one of my team members didn't know how to make those work correctly, so they just plastered images of them to make our repo look good. In actuality we have no coverage, no testing, no nothing...

As shared by a friend,
Beyoncé Driven Development (BDD)

Bae: come over
Me: can't, tests are failing
Bae: Flatmates aren't home
Me:

I was asked by our tester and scrum master to ignore some failing unit tests yesterday. The tester literally said "no time for tests, we need the build now". The scrum master is also a tester and agreed. I dont think I can respect either of them as testers anymore.

Comments for 'why', unit tests for 'what'

how the qa tests my code

I now know why people don't write tests.

Been trying to get started with React unit tests for weeks now.

Hope Driven Development FTW.

God bless tests. I keep finding really embarassing bugs 😂

They said, try new unit tests...

!dev && feelsbadman

I don't know what to think.
All I know is that I just went reaaaaal close to a disaster.

Friday morning, my "scariest" manager (as in, if you have to meet with him, it's usally for something serious) told me that he needed to see me on monday (so today) with the lead dev, the project manager and the dude who recruited me.

The meeting was like an arena of 4 vs 1, where they all 4 had problem with the work I do, as in I make a lot of small but stupid mistakes that wastes everyone's time. As an excuse, I suffer from sleep apnea so I wake up as tired I am when I go to sleep, and I snore loud as fuck. I've heard some records, it's not even human. (I'm 1m85-ish for 125 kg, it's BIG but with my morphology it's not like I'm a ball of fat)

Anyway. And since it's not the first time they're reproaching me this kind of stuff, they were all... really angry. Because I'm a nice guy, competent and all but not productive enough and easily distracted.

So, when the manager asked me to meet me, it was to fire me. However, during the lunch break, the lead dev found a solution: I get out of the current project I was in until this morning, and I write all the functional tests for all the projects, because they all lack quality and we sometimes deliver regresses.

They proposed me this in a way I could refuse, and I'd get fired because they had no other options. Obviously, I said yes, I'm not stupid enough to decline a possibilty to avoid a monstruous shitstorm that would have cut me my studies, the money for taxes, and a lot of fun to find a job as fast as possible.

But what surprised me the most is that they were genuinely glad I accepted, like, even though I made my shit ton of mistakes, they weren't pleased at all to get rid of me.

And in a way, I'm the one who won in this story, since I don't have to work with Drupal anymore, excepted to parse the website to write my tests, but my nightmare fuel is finally gone *.*

I don't know where to finish with this rant, but I needed to vent this whole thing, to write it somewhere so I can move forward.

I wish y'all a nice week.

Tests? Who cares? Deploy!

(true story... )

Some former colleague just blatantly commented out units tests I wrote for his build to pass. What the...

My app does not need tests!

build
D E S T R O Y E D

When you learn to write tests..

I am slightly upset about this shit

Today I fell down the rabbit hole.

I've been writing some automated tests which found an asymmetry in our algorithm which I think is caused by an off by 1 in even input dimensions.

Change input to odd dimensions, crash due to out of bounds exception.

Switch to debug mode to try to work out why we crash, failing asserts for default function arguments with no obvious reason beyond a helpful message saying they're unsupported.

We love unit tests.

How to pass tests, sooner or later
(free code camp)

Why we can't just rely on unit tests...

Client requests 100% test coverage..

someFunction();
expect(true).toBe(true);

Problem solved

I was with the train in Vienna already when suddenly I received an email that the test can't be held today because of technical problems 🙄

Now we have it next week when I also have to study for a maths test, do statistics exercises and exercises for database systems
Fml

Run tests locally... all pass. Run tests on build server... fail..

My co-worker not only doesn't create unit tests, he comment out my own unit tests after he changes the code and the test breaks.

*** writes unit tests with great zeal and fervor ***

IDE is reporting 85% line coverage, woohoo!

*** grins like a bastard, thinks it's perhaps time to stop and celebrate ***

*** runs branch/conditional coverage... ***

37%

*** facepalm ***

Write so many tests that QA goes out of job 😃😃

never wrote any unit tests

I did a job interview recently for a company and the test was something like this.

In ruby, write a web server that will serve a specific line number from a text file.

I thought up a simple solution and a more advanced solution, but I opted to go with the simple solution and submit my work quickly. I made a nice web server with tests and everything and it used the sed command to get the line number from the file.

Now, they had various instructions, like it had to perform. They asked how it'd perform with 10G, 100G files. I thought "Eh... it'll be alright."

The solution they were looking for was the "advanced" solution that I thought up, which involved storing a binary file of 32/64 bit integers that reference the byte-offset of the line they're looking for. Basically a binary index file.

This violates all of my sensibilities, because I would never build a database indexer like this using ruby, of all things.

I thought it was a stupid test, and how do these companies honestly expect me to spend hours coding and then tell me I didn't go far enough? It's unethical.

I actually followed-up with the "advanced" solution a couple hours after hearing I was out, just to show them that their process is flawed.

Tests passed: 1 / 1
Success rate: 100 %

Aww yiss

MOTHERF-

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.

I love TDD.

It's so relaxing to know that your fix didn't fuck up anything else when the tests pass.

"We don't have time for writing tests"
"Yeah we could write them but only if the client paid us for that"
"You can just test new features manually!"

- Most devs of our mobile team.

Every day they're fighting with bugs and when they're fixed, a couple more pop out of nowhere.

Dear god help me.

"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.)

I fucking HATE testing JavaScript. It's such fucking bullshit. I've been struggling to test one simple functionality for multiple hours. It's probably one stupid thing I can't figure out, so I hope some sleep will grant me a fresh look tomorrow.

Also it's absolute bullshit the amount of libraries and dependencies you need to have to get some proper scalable tests going. Jasmine, Babel, ES2015, yarn/npm (because Jenkins is too fucking old to handle yarn). React, react test helpers, webpack. The list continues. FUCK OFF!

"I'm almost done, I just need to write some tests"

Almost all fail

"Okay, maybe I need a few more days"

One of the best feelings when programming

and this is why continuous integration exists

Unit tests fail.

Re-ran it again without looking at details.

Unit tests pass now.

What. Why?!

Now I can't sleep at night.

a little confession: i've rarely used test suites in my projects (due to laziness and lack of time).

i've started a new project and now i HAD to write tests in order to make my PM happy.

Then i had to refactor a lot of code.

IT WAS SO EASY WITH TESTS.
I WAS A FOOL.
STUPID PAST ME, STUPID!

Pushing to prod without doing unit tests...

Boss coding.
Boss not fan of tests at all.

"Hey I'm doing all of tests" - boss to me.
"Cool, are they automated? Or do you want me to implement'em?" - me to him

[long speech about why tests are irrelevant including "...once I tested, it is tested, we dont need to have automated tests."] *im teaching you because you dont know voice*

Please, help meeee

A while back I feel asleep on the couch on the day of the state of the union address.

My deadass mind heard someone asking what the "state of the unit tests" was and I leaped up and said "there aren't any! i'm sorry, it's only a small project anyway".

Thank god no one else was there... 😂

A discussion about writing tests for frontend applications.

Context: my frontend coworkers don't write tests, at all. Yeah, really. Our testing process is very manual. We test manually when developing. We test manually when reviewing code. After merging, the application is deployed to a staging server and the design team does a QA Sprint. Lots of manual testing and some bugs still crawl by.

So I decided to start pushing my coworkers to start writing tests. One of the reasons I constantly hear them say to not write tests in the frontend is: "It's not worth the time, because design keeps changing, which means we have to take time to fix the tests. Time that we usually don't have."

I've been thinking about this a lot and it seems to me that this is more related to bad tests than to tests in general.

Tests should not break with design changes (small changes at least). They should test funcionality, not how things look. A form should not break if the submit button's style changes, so why should its tests fail? I also think that tests help save time, as they prevent some back and forth because of bugs.

Writing good tests is the hard part. Tests that cover what's really important and aren't frail and break with things that shouldn't break them. What (and how) should we test? And what shouldn't be tested?

Writing them fast is another hard thing. Are you doing it right if they take more time to write than the actual code?

What do you think about this? Do you write tests for your frontend applications? What do you test? How much time do you spend writing tests? What are your testing tools/frameworks?

That moment when your tests succeed on the first run after you've written them

Song lyrics as dummy text in unit tests

Not writing unit tests :(

Do you know that feeling when you finally have no more errors, but then you can't tell if the software actually does the right thing?

🤢

Wisdom of the day:
'No crashes' is not equivalent to 'it works'...

Not doing unit tests

Do you ever have those weeks where you have to fix a bug, then uncover another bug then another then another. Then you realise some functionality is completely missing. You write tests to cover your bug fixes and new functionality. Then you realise tests are broken with your fixes and you have no idea why. Then you get so frustrated you start making silly mistakes. Then your debugger starts playing up.... Yeah that's been my week.

how not to name tests

Not all unit tests are created equal...

True stuff here

I learned how to write tests.

Fuck the tests...

In my team, unit tests are called so, because every Dev is a 'unit' who manually tests their own code...

I skip writing unit tests. YOLO.

just saw a contract job "Write tests for existing codebase"....

When your tests don't even compile

How to force your self to write unit tests for your personal projects:
1. Go to a public place
2. Forget to bring your phone cable & never install a simulator because you are lazy af
3. Profit!

You don’t appreciate how large a project really is until you have to write tests cases for QA, to cover most work flows.

God this is mind numbing, only half way there... I think 😰

First Rant here.

So I was working on some integration test issues when I found this by accident made by a professional level SW engineer:

@Test
public void testMethod() throws ApiException {
Response res = null;
try {
res = serviceToTest.callMethod();
} catch(Exception e) {
assertNull(res);
}
}

Was wondering why tests were being green after some code changes I've made cuz tests could have not been green afterwards.

Together with a senior (I'm also professional only) I've tried to explain him for a good 1-2hrs why this code is useless and he still did it. Good thing there are no errors in the real implementation from him after fixing the tests as it's code freeze here and we are having go live in a few days 🙃

Also luckily he isn't working on our code anymore and has only been doing so for a few weeks.

Wasted a day with it and gonna check all of his code now before I run in the next surprise.

finally someone said it

I should to hire a guy who can write Tests for the code I write.

where unit tests connect to databases.. FML

"Coding se darr nahi lagta Sahab, Unit Tests likhne se lagta"

"Coding doesn't scare me Sir, writing Unit Tests does"

As a fresher, UTs scare me.

We're good here, let's push it to prod.

Do unit tests.

After a developer writes a 1000 lines of code with no unit tests then it is time to go home.

-Management puts unrealistic deadline as usual-

_Tries his best but fails to deliver on time_

*Puts a clearly visible bug in code*

~Tester finds it and creates a issue~

*Solves the issue, wraps up the remaining things and closes the issue*

**Wakes up from dream, cuz he is the tester as well**

PSA: negate your tests and make sure they fail!

I have what I thought was a weird and slightly paranoid habit. When I write tests sometimes just as a sanity check negate the assertion to make sure the test fails and isn't a false positive. Almost always fails as expected.

But not today! Turns out I had forgotten to wrap my equality check in an assertion so it would always pass. It freaks me out to imagine pushing a test that always passes not just because it doesn't do its job, but could also obscure a bug and trick me into thinking it works differently than it does. Broken tests are the worst!

But it pays to be paranoid.

Project has no tests

Getting beaten up over the quality of an app i'm working on with 6 interns. We have a bunch of unit tests, was shocked to see so many issues ... until I looked at the tests.

A function returning a non-optional array has 1 check ... that the return value is not nil ... fml

Am I the only one who gets extremely nervous the night before an interview as that technical test can encompass the entire academic field of CS. I'm just worried I'll forget the difference between a clustered and non-clustered index or fail to convey the difference between TDD and BDD.

I'm ten years in to my career now, so I 'should' know my stuff. I've produced the tests my self, hired other devs, but I still feel the nerves.

Do anybody here work with a codebase that actually has tests?

Or at the very least, the codebase has a domain layer, rather than puking lines of code randomly in the controller?

Am I trying to find an unicorn?

*hotfixing a project without unit tests in production*

I had no idea of how to implement the logic of a ticket. That's why I started with creating some unit tests that failed. Then I continued working until they all passed.

So it works now.

I have still no idea of how I implemented the logic.

I know I'm writing the correct integration tests when each one I add uncovers a new bug.

Still, it would be nice if just one of them passed first time.

Boss: "we're going to take over a project from another company. that's what we know so far - any other questions?"
Me: "do we get the history (svn/git) or just current source? unit tests?"
Other company: "no history for you. no unit tests - app was only tested manually"
Me: *sigh* :'(

Not learning unit testing... I've heard so many good things about them, but I've never learned how to inple.e t and use them.

Maybe I can start now, can anyone point me in the write direction?

Trying to love writing unit tests.

Those last couple of hours on a Friday afternoon in the office dragged out longer than the ending scene of part 3 of LOTR. Only I am pretty sure that the hobbits did not have circus music doodling in their heads while trying to write jest tests.

Just did an internship test for Autodesk and came away from it with the conclusion that I'm really stupid.
May as well give up on my dreams.

Me on Google right now:
"How to create Android unit tests"

Here's to actually being done with changes in the morning, a colleague requesting a lodash function call replaced by vanilla js, and my unit tests exploding as a result of the changes. Apparently lodash is far more forgiving than vanilla js about what you throw at it. That's my day gone. I need a drink. cheers!

In hindsight, this was entirely predictable

Let's get real serious for a second here guys... How do you unit test a unit testing framework?

I think I need to start writing unit tests for my unit tests...

When pinch-to-zoom didn't have enough tests....

That feeling when something you write works, and every part is tested. And your happy with it

!rant but wondering,
I'm doing Instrumented test for my android app, and wrote that code to check if the fragment loads data and click on first item and check if all is working as expected, am I doing it right?

Any help would be great :)
Warning: LIGHT theme ahead, room brightness is higher than my screen and I can't see shit in dark theme :\

When you see that green highlighted

OK ( # tests, # assertions)

"Why use tests anyways"

my coworker just disabled the unit tests in the build process

without telling anybody and without comment in the log

I was happy that my code worked then it was a little bit fishy that the build was so fast

I am so angry now and of course I need to fix the tests as well

I abhor timed code tests. Do you really want to test how fast I can write crappy code?

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

Is it just me, or are unit tests just overrated?

Oh lovely. There's a fucking bug in my tests, which I can't fucking reproduce.
Hahaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa 🙃

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.

Madness

Today I wrote the most epic code.

The kind that breaks your brain, but when you're done with it you know it's time to go home and kick back coz you've done good.

It used recursion, did backflips to avoid unnecessary db calls, featured no code repitition. Hell I even commented the business rules it was following in there to explain what was happening.

I hope it works tomorrow when I test it 😂😂😂

we dont need tests :/

Fuck Unit Tests.

I'm about to lose my freaking mind on intellij. Ran my tests yesterday and everything was good. I added a new method and a new test case today and suddenly no tests are found. Well they didn't go anywhere!! "Class not found, empty test suite" ... Lies! I've been messing with configurations for over an hour now. I just want to run my tests...

When a bunch of unit tests start failing locally because the AWS secret key got rotated.
oh wait...
THOSE AREN’T UNIT TESTS!!!
Unit tests do not depend on any external system, that includes AWS...
AAARRGHHHHH

Real men push to master and test in prod.

Overengineering. Finding the right point between overdesign and no design at all. That's where fancy languages and unusual patterns being hit by real world problems, and you need to deal with all that utter mess you created being architecture astronaut. Isn't that funny how you realize that another fancy tool is fundamentally incompatible with the task you need to solve, and you realize it after a month of writing workarounds and hacks.

But on the other hand, duct tape slacking becomes a mess even quicker.

Not being able to promote projects. You may code the shit out of side project and still get zero response, absolutely no impact. That's why your side projects often becomes abandoned.

Oversleeping. You thought tomorrow was productive day, but you wake up oversleeped, your head aches, your mind is not clear and you be like "fuck that, I'm staying in bed watching memes all day". But there's job that has to be done, and that bothers you.

Writing tests. Oh, words can't describe how much I hate writing tests, any kind of. I tried testing so many times in high school, at university, even at production, but it seems like my mind is just doesn't accept it. I know that testing is fundamentally important, but my mind collapses every time I try to write a single fucking test, resulting in terrible headache. I don't know why it's like that, but it is, and I better repl the shit out of pure function than write fucking tests.

That moment when unit tests twice bigger than code itself ...

I never write unit tests.

There, I said it.

Do you guys enjoy writing unit/ integration tests?

Start writing unit tests

Easy to pass the tests if you don't write any.

Some of my co-workers are so fucking dumb. Their thought process....

Let's re-run tests that are currently failing over and over until it works

😡

like bitch....fix it then run it! don't just run shit over and over to make yourself look busy.

Writing a small scale Ecommerce site for a friend. He keeps asking why I am writing tests for it all the time...some of us have standards

When you test only positive scenarios ;D

I hate it when I'm bug hunting and the fucking unit tests don't want to fail. Fuck you.

nodejs automated testing grunt mocha chai etc etc. Awwww yeaaaa

Making them unit tests pass

Working on a project with tests is so nice.
I love tests. Well, I hate making them, but now refactoring is so easy :]

TFW when you discover your tests have bugs, and your code was broken all along 😡

There is some gratification in writing tests and finding corner case flaws in your code. Don't worry past me, present me's tests got your back.

Too much technical debt
Write more unit tests
Unit tests failing, the code will be right so change the tests to pass
Too many unit tests to maintain, they look a lot like technical debt
Remove unit tests to reduce maintenance overhead

Change one line of code. Fix the tests for the next 6 hours. This is absolutely normal... NOT!

After finnishing all functionality defined in koncept our boss said that we should write some unit tests.

Wrote first one and already found 2 bugs.
I guess we should start with tests earlier 😅😷

Unit tests keep your sanity....sometimes

Setting unit tests that fail to ignore.

Somehow, a contractor left with all our unit tests six months ago. I just inherited this project. It's 200kloc of Django spaghetti, and I have no unit tests.

Speling eror is not my bug

Fix the Unit Tests to pass your Code!

Assertequals("Fail","Fail") in the catch block.
Things developers do to bloat their test coverage at my organisation,

Not writing tests for your code is like leaving it unguided in the hands of future Devs who gonna just change something and break the core logic and there won't be any regression test to run and check the integrity.

That joy of finally having them all passed.
I had stupid mistakes like: insertNewItem, but inside I use update T_T

project still fairly new, but this time I decided to write unit tests as I go instead of delaying till the end and writing nothing lol

Actually, it happened just before my current holidays.
I had prepared a whole system to feed and use a machine learning model. My colleague and some others had been working on a great thing, all encapsulated, all abstracted for my system.
My last day at the office, they had it ready.
I install their thing, load one model and launch one dummy prediction: error. I try with other input data: error
I try debugging a bit more, errors all the way. Knowing them, I asked if they wrote some unit tests.
"Sure we did"
I find the tests, yes there are some. And I notice:
"Hey, I see that in all your tests, you're making more than one prediction at a time (=aka using a matrix with more than one row)
- yeah, and it work fine
- in the project, we're doing one prediction at a time, did you try it with one prediction?"
He tries: error, that was totally what I said.
I started ranting on loosing the scope of the project, why we do tests in the first place.
Then, I grabbed my coat, said "see you in one week" and let them rework their code.
I was so angry at them, it seemed so basic to just check that 👹

When my tests pass AND CI succeeds. Or just when my php code works haha

I've finished the knowledge tests at the local DevJobCon and I got the following question on the easy part of the Java session:

Which of the following is NOT a Java IDE:
a) Eclipse
b) Netbeans
c) IntelliJ IDEA
d) Notepad++

😆

That feeling when your unit tests start passing...

My tests were failing in laravel 5 on my app, so I ignored them but when I went and dug into the test it was made for the default laravel page.

Make a small contribution to a github project, with tests because that was one of the requirements set by the owner. Owner then comments why I've made a test for this change... well... Because you asked for it. Be consistent. Either write tests for all functionality or don't bother at all. Now I feel like I've wasted my time.

I just found out I make tests best if I just don't care if I fail or succeed..

Looking at an old Java project, running java 1.6, test folder doesn't even exist and the "old but gold" java.utils.Date class is used throughout the whole thing. How do I initialise a new date again...? I actually just googled that :D At least the constructor parameters are named nicely... wait.. what...

That emotional rollercoaster when you refactor a huge mess and finally there are no more compile errors in it. But there are still endless broken tests to fix :(

Hell yer.... Feels as good as all tests passing.

Ah perfect... Now none of the unit tests pass...

Never doing unit tests...
Too lazy

All tests passed. Now I can sleep peacefully.

Me 🤗"Since you know the domain far better than me, can I ask you to help me understand if I managed to cover all the edge cases with these UNIT TESTS?
😒" no no no, you don't need to check for those cases, you already do that in your code"
🤗 "I'm sorry, I must have explained myself badly. I have written these UNIT TESTS exactly to ... TEST if those CHECKS in my code work and what I need is you to tell me if there are additional cases ..."
😫"but you don't need to!!! You already have that logic in your code"
😐😵☠ 🦍💊🔫🔪"you know what? I'm gonna give them a second look. Thanks"
And then I moonwalked out of the room

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.

Write code. Write tests. Everything passes and you go home happy. Come to work next morning, run tests again just to be sure. Everything fails.

Couple of weeks ago I received a negative response about a code test I did for a front and position. They only said I was not a good fit.

Today, I received another email from them, asking me to do a test. I asked for clarification, and they said they are giving me a chance to redo the test.

Sounds weird, but I'll redo the test anyway. The task is to code a responsive page that consume an api. I'm using vue, sass, git, modular and semantic code. What else should I focus?

The deadline is in 36h.

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!

What the fucking fuck. Arquillian you piece of shit.
I have a service that needs to go to production soon, it contains Arquillian tests. The tests work locally but not when going through our new Jenkins pipeline. The error message simply says: "Could not start Arquillian container".
Well fuck you too.
After 3 fucking days of rewriting configs, changing up things and I dont know what else I did, I stubled upon the most hidden error message in the history of error messages, a small little line that says "Could not find or load main class ".
Those 2 spaces are intentional btw, because the fucking error was that when starting arquillian and reading the config there was A FUCKING SPACE too much in my JVM arguments. This piece of shit iterpreted it as my FUCKING MAIN CLASS. Whhhhyyyyy, whhhyyyy. Who the fuck... AAAAAAAAAHHH

Btw I snuck myself on devrant a few weeks back and managed to get my 100++ today. Really love this place 😊

I promised to blow off unit tests, so here we go. Let’s talk about unit tests.

Why use them? So, unit testing connoisseurs outline two big purposes:
1. To keep application integrity,
2. To catch bugs.

Keeping app integrity is when your freshly hired developer implement something that potentially leads to the whole app failure, but unit test fails and tell you that newly added code is breaking the app.

Catching bugs is pretty much self explanatory. Just think about it – you have to actually write code that describes how to check up another code to catch bugs in it.

I personally hate unit tests. I can’t explain, but every time I forced myself to write them, I got vertigo and terrible headache to the end of the day. Trying to write some tests? Here you go, wooosh and you can’t work anymore. Go get some sleep if you can.

But I still needed my job to be done and it should have been done really well. So I started my research.

Recalling Steve McConnell’s and many other classy developers’ experience, there is only one decent solution that prevents bugs and inconsistencies at large scale – the specs. Developing the specs should be considered the task number one. With decent, robust specs, app is almost guaranteed to contain no bugs.

Let’s take a look at the piece of great spec. For example, imagine you have to implement validation logic. So you state that validation should be implemented with special validation functions and then you define what validation function is: a pure function that accepts a value and returns boolean: true if value is good, false otherwise.

With that in mind, it’s obvious that potentially present bugs can only be inside that pure functions. Our spec made implementing validation very easy and idiomatic, isolating potential bugs. As soon as validators are pure and simple, unit tests aren’t needed at all.

You know what? As your app scales, you’ll definitely need a spec, sooner or later. Growing up without spec leads to irreversible failure, your app will grow like cancerous cell does and it’ll be easier to just put it into trash and start up from scratch.

But specs have one major downside – it requires at least one enlightened developer with really great experience to create it. It can’t be done quickly, it’s a very costly and difficult process. That’s why making great software costs that much.

But what if you need an MVP right now?

Speaking of MVPs, you’ll have to go with simplest instruments possible. Throw away Jenkins, use your Plesk autodeploy from Git repo. Throw away complex frontend setups, go with $30-$40 glittery ui kit or even an open source thing right from CDN, without less, sass, gulp and all that jazz. Make use of create-react-app if you can’t avoid using React because you’re making a web application.

Throw away AWS, Azure, Docker, Kubernetes and everything like that. Buy a cheap PHP7 hosting with pre-installed MySQL and do everything as simple as possible. If you have to use NoSQL, go with free Heroku with git autodeploy, NodeJS Express and free Mongo addon.

MVP should be ready in two weeks. As soon as your infrastructure is that simple, you don’t need unit tests. They’ll slow you down. Once you MVP is ready, go get funding, throw away first MVP, hire a decent CTO and let him create the spec.

Right there, it may be noticeable that unit tests are probably the biggest and baddest workaround imaginable. It gives you false sense of controlling your bugs, while you don’t have any control at all. Obvious bugs that unit tests can catch are easily noticeable at concise system, while quirky bugs couldn’t be caught by them because you can’t even imagine them while writing your unit tests. At this point, unit tests are just waste of time.

So, the whole picture is clear: at a small scale, you don’t have time to write unit tests and don’t have many bugs because of simple tools and standard patterns. At large scale, you need a spec to prevent bugs, unit tests become redundant as long as your spec is good.

In conclusion, I can tell that I’ve been developing a Clojurescript + CouchDB app for some startup, and in 8 month coding by spec I made myself I encountered only two or three bugs, all related to external JS tools and its quirks.

Have a good time!

I've been compiling the project for about 5 hours now, still no successful build due to bad tests generating intermittent test failures...

All I wanted to do was to release the web project to the customer not fucking wrestle Cthulhu!
The worst part is that the release is set up so that you need to release the entire project internally before you can release one part.

Boss wanted our AES implemented to use an Initialization Vector. I changed the implementation to add an IV and all the tests passed on the first try!

I changed the implementation to fail just to make sure I wasn't getting false positives.
