Kind of a great video! I enjoyed it. His point about testing coverage and generating mutations to ensure the tests fail resonated. I get concerned sometimes that the AI is writing tests not to ensure the logic is correct, but to ensure the tests pass against the code it already wrote. Any other ideas on this? Is there a code review step or CI checkpoint that would decrease the likelihood of that?

To be fair the overwhelming majority of tests I've seen in the wild written by humans have been the same. Not a lot of good material for AI to learn from.
