Thanks - that's the next thing I was going to ... rail at. Some consultants who teach TDD use a mind-trick to motivate their newbs to decouple their code. In a big-iron environment where database _migrations_ are expensive, until you pay that down, you can get a slight benefit to unit tests that reach into code that decouples from the database. We should do that too. And when we need a fixture, to start such a test case, it should come from the database. -- Phlip --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.
