I actually really like this approach, and have been thinking about this in regards to coding with an LLM - for a sufficiently simple program (and assuming no security concerns), once you trust your test suite, you should trust AI generated code that passes it. And then if requirements change, you should be able to amend the test cases, rerun the AI until it passes all tests and linters, maybe give the code a quick glance, and be on with your life.
