“No Duh,” say senior developers everywhere.
The article explains that vibe code often is close, but not quite, functional, requiring developers to go in and find where the problems are - resulting in a net slowdown of development rather than productivity gains.
Unit tests aren’t intended to find bugs, they’re intended to prove correctness. There should be a separate QA process for finding bugs, which involves integration testing. When QA inevitably finds a bug, the unit tests get updated with that case (and any similar cases).
And that’s what code reviews are for. If your tests don’t sufficiently cover the logic, the change should be rejected until they do. It’s a lot easier to verify the tests cover the logic if the tests are submitted w/ the logic changes.
