Yes, this comment thread has correctly pointed out that my understanding of TDD was and still is incomplete. I think there's some aspects of TDD (such as refactoring after implementation) that I'm not interested in. The two folks I know who are big TDD proponents tend to gravitate towards test first development (TFD). In my mind, that was TDD. You write the tests and that drives how you develop the tests.

In a recent personal project I started using tests on a bit of a whim and found an unexpected benefit that I wanted to share.
