I think “test the function does what it does” is not necessarily the intent here, it’s being able to write tests that fill themselves in and assuming you’ll double check afterwards.

That said, I don’t see how it’s much different to TDD (write the test to fail, write the code to pass the test) aside from automating adding the expected test output.

So I guess it’s TDD that centres the code, not the test…
