I was a big fan of the unit testing done at JP Morgan. I found 1 exploitable bug when writing Unit Tests, for an untested swath of code that was of minor concern. Ofc this was one day out of a ticket that took a few days. After a year, when I left, it was the only bug that I found with a unit test, there. I wrote unit tests for everything during my time, and I found it to be a good practice. Do I always do it at other workplaces? No. Do I do it for my own projects? Yes. It's not that I don't care as much at work, but the time pressure is constant and I sometimes skip them if I can.
