Context:
I left a job a couple of months ago. This company was super disorganized and every day, I heard everyone complaining about how something broke in production. I stayed quiet for a couple of weeks but this continued on. Finally, I asked several people if I could write some tests, even if they were just for crucial parts of the applications we were building.
Weird Advice:
One of the developers responded that he didn't recommend writing tests because there was a good possibility they would fail. I was a junior in this position and he was kind of arrogant so I tried to push the issue in a lighter manner by explaining all of the benefits. He still kept telling me no say I finally explained to him what writing tests really meant and how failing tests show us where/how/why/etc things broke so we can fix them much faster. He just ignored me from that point on, and then I left a few weeks later.
