But the purpose of a test is to catch a bug before it goes live.
The discussion went from tests being written by ai, to nobody actually reviewing the tests, to the claim that given those circumstances, you wouldn't notice that the tests may not tests anything anymore because of mocks.
My statement was merely pointing out that your previous comment was groundless because they still would've found out about those bugs when they went live.
Maybe. You're assuming visible and obvious bugs.
