That sounds to me like an ad-hoc definition of test-driven development:
Basically the workflow is:
1. Write a minimal test that fails, e.g.
prop_square ==> 2 ** 2 == 4
2. Write just enough code that the tests pass, e.g.
_ ** _ = 4
3. Go to (1) and add a slightly more complex test, e.g.
prop_square x ==> x ** 2 == x * x
You can consider (1) to be defining, programmatically, a requirements
document for a desired change.
Apologies if I have messed up the quickcheck notation, I haven't written
quickcheck tests for a while. (**) is (obviously) supposed to implement
