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.
And please for the love of all that is holy… DO NOT let some smuck go through setting up a test platform with all defaults and cause thousands of notifications per minute without any plan on actually addressing notifications (by either actually fixing the issue or tweaking thresholds for your specific situation.)
Else all the system does is train people to become apathetic to notifications and warnings. I once was on an IT Team that had read notification boards and 104k notifications… and all they did was joke about it… seriously… turn off the system then.
