The advice that everyone seemed to agree on at least just a few months ago was to make sure _you_ write the comprehensive tests/specs and this is what I still would recommend doing to anyone asking. I guess even this may be falling out of fashion though…

Generate with carefully steered AI, sanity check carefully. For a big enough project writing actually comprehensive test coverage completely by hand could be months of work.

Even state of the art AI models seem to have no taste, or sense of 'hang on, what's even the point of this test' so I've seen them diligently write hundreds of completely pointless tests and sometimes the reason they're pointless is some subtle thing that's hard to notice amongst all the legit looking expect code.

There is no need to write tests manually. Just review the tests, and make sure there is good coverage, if there isn't ask AI for additional tests and give it guidance.
