Well, correctness testing is just a special case of termination testing (a bug free path becomes a terminating path). Turing
proved over 50 years ago that exhaustively proving a non-trivial program would terminate is impossible. It is a small jump to show that proving any non-trivial program is bug-free is also impossible. So if we have an impossibility against a test that guarantees a bug free program it becomes a game of good enough. IN OS X land, good enough seems to be pretty damn good. In Windows land, good enough is a nightmare.
