Employer: Hey, we are moving an API update live tomorrow morning that could affect our apps. Can you regression test the apps to make sure they all work?
Me: The API team is pushing code overtop of live endpoints that can break them?
Employer: Yes, we need the updates to work with a new product we are developing.
Me: And nobody thought about versioning these endpoints so we guarantee uptime on all existing services using them now?
Employer: We looked at that but it cost extra and required us to use the cloud solution so we don’t use versioning.
Me: Okkk… I also take it that the API’s don’t have integration tests written?
Employer: What are integration tests? Are unit tests the same thing?
Me: No, so when do I need to regression test all 7 production apps?
Employer: The API’s are moving to production at 4am and we need it signed off by 7am.
Me: I only have 3 hours to regression test 7 production apps at 4am? Each app, if I just skim over them, would take me 2 hours each. I will do my best but that’s a very short time to ensure complete functionality.
Employer: Don’t you have unit tests?1 -
Unpopular opinion: unit tests are often overrated.
Although a well written test suite is almost essential in some parts of the application (I.E. business logic) I cringe when I see hundreds or thousands of line which “mocks” everything to test a micro service which just does CRUD operations on a database, in cases like that unit tests are just a waste of time because almost every operation involves a mock which may not behave like the real database and often needs to be rewritten when the code undergoes a huge refactoring. In these case a integration test suite is faster to write and way more helpful.7 -
Supervisor: YOU NEED TO INCREASE THE COVERAGE OF YOUR UNIT TESTS! THE FILE logger.js DOESN'T HAVE >80% COVERAGE! IMAGINE PICKING THIS UP 6 MONTHS FROM NOW!
Bro. It's a Winston instance.
I am literally exporting a fucking Winston instance with 0 custom logic.
If 6 months from now I take a file and can't understand a Winston instance anymore, you're well within your right to fire me on the spot.2 -
Just got a new job at an old school hardware company. The codebase is giving me heart attack. They don't care about dev experience or code navigation at all. Every attempts to modernize the codebase is so half assed. All patches are so bloated that make the codebase even worse.
Frontend is migrated from prototype-oop-jquery cluster fuck to AngularJS, then finally angular. Holy moly, all business logics are baked into UI "classes" using prototype chain. When they migrated to AngularJS, someone simply added a wrapper to that jQuery cluster fuck class and overwrote all the prototype with a 10k +lines file. Since all the methods are hidden in either prototype, JS object, or callback function, it's impossible to trace the data pipeline using IDE when "go to definition" on update() method gives you all the update methods/string in all objects/classes. And they don't care about immutability. References are taken out, renamed, and mutated everywhere. Finding the source of a bug is fucking guessing game.
I don't know what trick they use that makes cLion static analyzer fail.
And there is no unit test or spec doc.
Fuck me dead3 -
There are devs who are chill. Then there's me. Deadlines give me anxiety. Being responsible for the code I didn't write and being blamed for the bugs I inherited stress me out.3

probably every time I see my tests failing.
Each time I am writing tests I'm convincing myself "it's an investment", "spend 2 hours now to save 2 days later", "unit-tests are good".
And each time I'm chasing away ideas like "perhaps they are right, perhaps writing unit tests is a waste of time..", "this code is simple, it should ever break - why test it??", "In the 2 hours I'll spend writing those UT I could build another feature"
Yes, it is terribly annoying to write tests, especially after writing the production code (code-first approach). Why test code that you know works, right?
But after a few weeks, months or years, when the time comes to change your feature: enhance it, refactor it, build an integration with/from it, etc, I feel like a child who found a forgotten favourite candy in his pocket when I see my tests failing.
It means I did a very good job writing them
It means it was not a waste of time
it means these tests will now save me hours or days of trial-and-error change→compile→deploy→test cycles.
So yeah, whenever I see my tests fail, I feel warm and fussy inside :)3 -
There are a couple:
A system that updates user accounts to connect them into our wifi system by parsing thousands of processing files written in Clojure. The project was short lived and mainly experimental, It has complete test cases and the jar generated from it is still purring silently on the main application. It was used to replace an $85k vendor application that made no fucking sense. The code has not been touched in 2 years and the jar is still there. The dba mentioned the solution to the vendor, the vendor tried buying it from me, but being that it belongs to the institution nothing was touched, still, it got the VP's attention that I can make programs that would be bought for that level, it caught his attention even more when I showed him the codebase and he recognized a Lisp variant (he is old, and was back in the day a Fortran and Cobol developer)
A small Python categorical ML program that determines certain attributes of user generated data and effectively places them on the proper categories on the main DB. The program generates estimates of the users and the predictions have a 95% correctness rate. The DBA still needs to double check the generated results before doing the db updates. I don't remember how I coded it because I was mostly drunk when I experiment on the scenario. It also got the attention of the VP and director since the web tech manager was apparently doing crazy ML shit that they were not expecting me to do, it made them paranoid that I would eventually leave for a ML role somewhere, still here, but I want more moneys!!
A program that generates PDF documentation from user data, written in Go, Python and Perl (yes Perl) I even got shit from the lead developer since I used languages outside of their current scope of work. Dude had no option but to follow along with it :P since I am his boss
Many more. I am normally proud of my work code. But my biggest moment is my current ntural language processing unit that I am trying to code for my home, but I don't have enough power to build it with my computers, currently, my AI is too stupid, but sometimes it does reply back to my commands and does the things I ask it to do (simple things, opening a browser, search for a song etc) but 7 times out of ten it wont work :P -
If you're subscribed to me only because of my jokes, feel free to ignore this rant. You won't miss anything.
If not, bear with me.
I was wrong about almost everything I can remember. Preaching so-called “conceptual thinking”, I invented a fantasy world of random anecdotes, which turned into a completely false worldview that shaped my reality. I bashed magical thinking, yet succumbed to it. What I believed to be true was just as magical, wrapped into what sounded like science. In the Dunning-Krueger scheme, I was right there on Peak Stupid.
Random hear-say, stupid concepts I invented, random “knowledge” I picked from YouTube videos, all that was rotting inside my head, one anecdote contradicting another. Ultimately, I think this was the reason of my constant anxiety and pointless, never-ending thought process in background.
If you learned anything factual from me and didn't fact-check it, please forget that immediately. The list includes but is not limited to everything on brain structure, everything on philosophy, almost everything on engineering and architecture, almost everything on systems theory and programming meta stuff (declarative, imperative, etc.)
I admit bashing unit tests. The only reason was me disliking writing them in uni. I wrote like three test cases, disliked it, and the rest was history. Everything else was a rationalization on top. If I was right about something, I was just lucky.
I'm not a CSS prodigy. I know stuff that earns me money and impresses my colleagues, but my knowledge is just one step above basics, in one thousand steps ladder.8 -
I gave a rant yesterday about this. But I have to say it again because it's so gratifying. It went like this
Me: "you should patch the module instead of using it for your python unit test."
Them: "You keep telling me this, but maybe there is a better way"
Me: "there is, I'm telling it to you"
Next day, Code review.
Me: "You need to change this"
... silent on the issue ...
On a call...
Me: "You need to patch the module. Don't mess up the namespace."
Them: "I don't think so, X did the work"
(In my head: then what did you do)
Me: "We can grab whoever you like Y, X. Let's see if X is busy"
... X isnt busy, hops on call 45 seconds later.
Me: "we're using the module, we should patch this'
X: Muses the thought for 2-3 seconds.
X: "yeah... Yeah we probably should patch that"
Moral of the story, don't take shit personally unless your right... Then relish in. But if your right and X says otherwise, you can always + a rant. -
Looking for someone to test a new factorization script I wrote.
https://pastebin.com/Td2XTKe6
Tested against a set of products from all primes under 1000. Worked even on numbers up to 87954921289
Worked for about 66% of the products tested.
Obviously I'm cheating a little bit because I'm checking for four conditions n%a == 0, n%a == 1, n%b == 0, and n%b == 1
It appears it is possible to generate the series from just the product, and then factor each result. The last factor in each each set of factors becomes x, and we do p%x and check for zero.
if it works, we've found our answer.
Kind of wonky but basically what its doing is taking p, tacking on a 0 to the right, and then tacking p to the right of *that*.
So if you had a product like
314
The starting number we look at is
3140314
The middle digit becomes i, and the unit digit becomes j.
Don't know why it works more often then not, and don't know if it would really be any faster.
Just think it's cool.9 -
unit test apologist: what’s your fetish?
Me: I like curves. You like that?
unit test apologist: no, I like…3 -
Currently having very funny project lead, who gives on the spot estimates for 9 years old very pathetic quality code having Android app in security domain. Memory leaks, bad practices, typos, CVEs etc. you name it we have it in our source of the app.
Since 5-6 sprints of our project, almost 50% of user stories were incomplete due to under estimations.
Basically everyone in management were almost sleeping since last 7-8 years about code quality & now suddenly when new Dev & QA team is here they wanted us to fix everything ASAP.
Most humourous thing is product owner is aware about importance of unit test cases, but don't want to allocate user stories for that at the time of sprint planning as code is almost freezed according to him for current release.
Actually, since last release he had done the same thing for each sprint, around 18 months were passed still he hadn't spared single day for unit testing.
Recently app crash issue was found in version upgrade scenario as QAs were much tired by testing hundreds of basic trivial test cases manually & server side testing too, so they can't do actual needful testing & which is tougher to automate for Dev.
Recently when team's old Macbook Pros got expired higher management has allocated Intel Mac minis by saying that few people of organization are misusing Macbooks. So for just few people everyone has to suffer now as there is no flexibility in frequent changing between WFH & WFO. 1 out of those Mac minis faced overheating & in repair since 6 months.
Out of 4 Devs & 3 QAs, all 3 QAs & 2 Devs had left gradually.
I think it's time to say goodbye 😔4 -
My fellow developer was given a responsibility of writing unit test cases.
And instead of mocking the db calls he ended up making actual calls to db and adding realtime data to firestore everytime a test runs. Also he used mocha for the same. When i told him that we need to mock the db calls he said he will use sinon.js for the same and for code coverage his plans were to use istanbul.
I was like FUCKKKKKKK. , why the fk you aren't using jest. I mean whyyyyyyyy. WHAT THE FK4 -
Read this and tell me OOP (or at least C#) isn't broken:
https://levelup.gitconnected.com/5-...
All I want to do is mock System.DateTime is for a few of my tests, and I ended up going down this rabbit hole of absolute horseshit: build a custom class that you can mock in tests, blah blah blah blah, uhhhh... YEAH NO
Such a simple functionality / need, and yet there is no easy way to test for it. Sigh.16 -
In most businesses, self-proclaimed full-stack teams are usually more back-end leaning as historically the need to use JS more extensively has imposed itself on back-end-only teams (that used to handle some basic HTML/CSS/JS/bootstrap on the side). This is something I witnessed over the years in 4 projects.
Back-end developers looking for a good JS framework will inevitably land on the triad of Vue, React and Angular, elegant solutions for SPA's. These frameworks are way more permissive than traditional back-end MVC frameworks (Dotnet core, Symfony, Spring boot), meaning it is easy to get something that looks like it's working even when it is not "right" (=idiomatic, unit-testable, maintainable).
They then use components as if they were simple HTML elements injecting the initial state via attributes (props), skip event handling and immediately add state store libraries (Vuex, Redux). They aren't aware that updating a single prop in an object with 1000 keys passed as prop will be nefarious for rendering performance. They also read something about SSR and immediately add Next.js or Nuxt.js, a custom Node express.js proxy and npm install a ton of "ecosystem" modules like webpack loaders that will become abandonware in a year.
After 6 months you get: 3 basic forms with a few fields, regressions, 2MB of JS, missing basic a11y, unmaintainable translation files & business logic scattered across components, an "outdated" stack that logs 20 deprecation notices on npm install, a component library that is hard to unit-test, validate and update, completely vendor-& version locked in and hundreds of thousands of wasted dollars.
I empathize with the back-end devs: JS frameworks should not brand themselves as "simple" or "one-size-fits-all" solutions. They should not treat their audience as if it were fully aware and able to use concepts of composition, immutability, and custom "hooks" paired with the quirks of JS, and especially WHEN they are a good fit. -
I hate unit test. I hate testing by code.
I hate the idea to write code that tests code. And that u must update both when u add a feature. Like wtf.
Good debug mode with clear verbose and precise reporting tool and voila.
Drives me nuts thus trending shit.10 -
A year ago I built my first todo, not from a tutorial, but using basic libraries and nw.js, and doing basic dom manipulations.
It had drag n drop, icons, and basic saving and loading. And I was satisfied.
Since then I've been working odd jobs.
And today I've decided to stretch out a bit, and build a basic airtable clone, because I think I can.
And also because I hate anything without an offline option.
First thing I realized was I wasn't about to duplicate all the features of a spreadsheet from scratch. I'd need a base to work from.
I spent about an hour looking.
Core features needed would be trivial serialization or saving/loading.
Proper event support for when a cell, row, or column changed, or was selected. Necessary for triggering validation and serialization/saving.
Custom column types.
Embedding html in cells.
Reorderable columns
Optional but nice to have:
Changeable column width and row height.
Drag and drop on rows and columns.
Right click menu support out of the box.
After that hour I had a few I wanted to test.
And started looking at frameworks to support the SPA aspects.
Both mithril and riot have minimal router support. But theres also a ton of other leightweight frameworks and libraries worthy of prototyping in, solid, marko, svelte, etc.
I didn't want to futz with lots of overhead, babeling/gulping/grunting/webpacking or any complex configuration-over-convention.
Didn't care for dom vs shadow dom. Its a prototype not a startup.
And I didn't care to do it the "right way". Learning curve here was antithesis to experimenting. I was trying to get away from plugin, configuration-over-convention, astronaut architecture, monolithic frameworks, the works.
Could I import the library without five dozen dependancies and learning four different tools before getting to hello world?
"But if you know IJK then its quick to get started!", except I don't, so it won't. I didn't want that.
Could I get cheap component-oriented designs?
Was I managing complex state embedded in a monolith that took over the entire layout and conventions of my code, like the world balanced on the back of a turtle?
Did it obscure the dom and state, and the standard way of doing things or *compliment* those?
As for validation, theres a number of vanilla libraries, one of which treats validation similar to unit testing, which seems kinda novel.
For presentation and backend I could do NW.JS, which would remove some of the complications, by putting everything in one script. Or if I wanted to make it a web backend, and avoid writing it in something that ran like a potato strapped to a nuclear rocket (visual studio), I could skip TS and go with python and quart, an async variation of flask.
This has the advantage that using something thats *not* JS, namely python, for interacting with a proper database, and would allow self-hosting or putting it online so people can share data and access in real time with others.
And because I'm horrible, and do things the wrong way for convenience, I could use tailwind.
Because it pisses people off.
How easy (or hard) would it be to recreate a basic functional clone of the core of airtable?
I don't know, but I have feeling I'm going to find out!1
