I don't know about you, but I feel really exhilarated when I cover a functionality with unit tests. In reality, we can rarely start with the tests up-front (TDD-style), or even cover a functionality with tests before a realese. Deadlines often prevail, you know. Yet, once I cover a feature with enough tests (even after the fact), it is as if a 10-ton rock is falling off my shoulders. I can finally free my head, and move on, without anticipating when the thing will crash in production.#microblog
