> Meanwhile, AI is happy to write tests, do red-green TDD cycles, refactor them, prune them, update them, justify and defend them. It will even incidentally write tests for the most aloof vibe-coder by accident because they didn't specify otherwise.

I read some AI generated tests and while it looks visually impressive, ultimately it wasn’t doing anything valuable? Why? because of all the mocks and scenarios that didn’t matter. And on top of that, tests are additional code to maintain.

These days, I don’t even bother with unit testing. They are a maintenance burden. I focus on integration test (whole modules) and if I have the time, on a harness to do e2e testing.
