What is the essence of TDD?

It kinda irritate me when people talk about TDD being write test first before you write code – and simply stop there. I don’t think this sufficiently captures the essence of TDD, and I suspect that in some cases this is simply regurgitation of some textbooks.

To me TDD is also:

  1. Treat unit testing as a first class process in the SDLC
  2. Use unit test as a key quality control mechanism
  3. Design your code and architecture so that it is testable
  4. Treat and maintain test code as first class citizen

What is TDD to you?
