Possibly stupid question: is automated testing actually a common practice? (programming.dev)

Referring more to smaller places like my own - few hundred employees with ~20 person IT team (~10 developers).

I read enough about testing that it seems industry standard. But whenever I talk to coworkers and my EM, it's generally, "That would be nice, but it's not practical for our size and the business would allow us to slow down for that." We have ~5 manual testers, so things aren't considered "untested", but issues still frequently slip through. It's insurance software so at least bugs aren't killing people, but our quality still freaks me out a bit.

I try to write automated tests for my own code, since it seems valuable, but I avoid it whenever it's not straightforward. I've read books on testing, but they generally feel like either toy examples or far more effort than my company would be willing to spend. Over time I'm wondering if I'm just overly idealistic, and automated testing is more of a FAANG / bigger company thing.

especially if the code has been written in a way that makes it difficult to write a robust test.

I definitely deserve a lot of blame for designing my primary project in making hard to test. So, word to the wise (though it doesn't take a genius to figure this out), don't tell two fresh grads and a 1 YoE junior to "break the legacy app into microservices" with minimal oversight. If I did things again, I still think the only sane decision would be to cancel the project as soon as possible. x.x

I actually was using a mock webserver with the expected request/response, which sounds like what you're getting at. Still felt fiddly though and doesn't solve the huge mock data problem which is more an architecture design failing.

I've mostly gotten away from testing huge methods with a seemingly arbitrary numbers in favor of testing small methods with slightly less arbitrary numbers, which feels like a pretty big improvement.

How are you gonna get good at it if you don’t do it! :D

True. :)

Hahahahaha I feel that re: just kill the project!

Ah I thought you were just mocking the response, as opposed to having some real webserver so you don't have to faff with mocking stuff. Sounds like you did what I would have :P

That does sound like a big improvement! Anything you can do to make your own job easier
