Believe me, I take Dijkstra's message to heart. And a quality test suite can reify the decisions of a formal specification as expressed in PTS or some other suitable abstraction. Think more here's the proof, more or less rigorous as circumstances suggest reasonable, and here's some tests that capture as much of that in code as practicable to help give us some further confidence that we didn't err in our manipulations.
