The fact that when this blog post says TDD, it means "writing unit tests" is really annoying. TDD is a methodology of writing features by writing tests first to define the behavior you're targeting, then writing code to match that behavior. That is different than "write code, then write tests to assert the behavior of your code." You can have excellent tests and excellent code coverage and excellent behavior documentation without doing TDD.
