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.
yes, it’s very common in my region. 50% of companies I worked at had CI servers that ran unit tests round the clock. the companies are only slightly bigger than yours. also i know multiple companies my company worked with also have CI setups.
some even auto deploy to prod when the tests in master passed okay.
most use hudson or jenkins for CI with junit, phpunit, selenium and/or cypress for testing.
