  > There's a certain sense of satisfaction in knowing I've tested a piece of code per my experience in the domain coupled with knowledge of where we'll likely be in six months. 

one of the other important points about writing unit tests isn't to just to confirm the implementation but to improve upon it through the process of writing tests and discovering additional requirements and edge cases etc (tdd and all that)

i suppose its possible at some point an ai could be complex enough to try out additional edge cases or confirm with a design document or something and do those parts as well... but idk its still after-the-fact testing instead of at design-time its less valuable imo...
