I've found that there are tests and there are well-thought-out tests. If tests police your development, then they need to be held to the highest standard. Quis custodiet ipsos custodes? Beyond the basics, those tests have to be testing something worth testing.
I have a DBT project that runs nearly 8,000 tests. Obviously, these tests run far faster and more reliably than a human could ever hope to achieve, yet I have a nagging doubt that not all of these tests are useful. Time-consuming, yes, and as the CICD pipeline runs in the cloud, costly as well.
AI is good at generating tests, but expect to prune what it generates.

Amen. I've been at least reading (if not always doing) Test Driven Development (TDD) since the early 2000s. Thanks, Kent Beck and "Uncle Bob" Robert Martin. I've done it as a programmer, and am trying to do it more as a business intelligence person. As you suggest, I think this is something that AI will be good at helping with.
