This is why I've been pushing back on the "just have the AI generate the tests!" mentality. Sure, let it help you, but those tests are the guarantee of quality and fit for purpose. If you vibe code them, how the hell do you know if it even does what you think it does?

You should be planning out the tests to properly exercise the spec, and ensuring those tests actually do what the spec requires. AI can suggest more tests (but be careful here, too, because a ballooned test suite slows down CICD), but it should never be in charge of them completely.
