Test Smell Review

A test suite that is 100% green is not proof the code is correct — it is only proof that no test failed. Apply this judgment whenever tests are written, edited, or explicitly reviewed: a test is useful only if some incorrect implementation would make it fail. If no such implementation exists, the test is structurally green regardless of whether the code is right.
