I work with people who openly believe that unit testing is a waste of time. Personally, I think they are afraid, because they don't even know how, and don't care to learn. They would see that title, and that's all the confirmation bias they would need.
Err, my apologies if that came across as a slight, I literally meant you and a lot of other folks made the exact same mistake. No judgement intended, it's clearly a common misapprehension.
My guess is that a lot of folks got introduced to unit testing through test-driven development and, as a result, conflate the two, assuming the former necessarily implies the latter.
Speaking for myself, I was writing UTs long before the TDD fad landed and so I never picked up the habit. It's just not the way my developer mind works, and I've not found it compelling enough to try and re-train myself.
That said, not believing in the value of automated regression test (of which UTs are the lowest hanging fruit) is utter madness...
