I restrict that to "every proper behaviour the system is expected to provide should be tested". The corollary is that every behaviour is either: * part of an expected external behaviour, and thus unit tests need to assert that behaviour through the unit's public interface * not part of an expected external behaviour, and thus needs to be removed from the system This also forces a decision about "private" functionality: Either it's part of some public functionality, and thus needs to be tested via that public functionality; or it's not part of any public functionality, and needs to be removed. > It's my understanding that unit testing (a.k.a.
