I more often verify a couple test-cases by hand and encode those, paying
special attention to boundary conditions, etc.

Some situations are complex enough that they warrant test hooks to
verify intermediate results. And, yes, I leave the hooks in. E.g., "if
(test) test->VerifyIntermdiateX(y,z);" Make sure the test-hook pointer
is 0 for production.
