What is TDD? 

Test-driven development (TDD) is a software development process that relies on the repetition of a very short development cycle.

The act of writing a unit test is more an act of design than of verification.  It is also more an act of documentation than of verification.  The act of writing a unit test closes a remarkable number of feedback loops, the least of which is the one pertaining to verification of function (Robert C. Martin, 2002).

TDD = Refactoring + TFD

One view is the goal of TDD is specification and not validation (Martin, Newkirk, and Kess 2003).

The Steps of test-first development (TFD).

The two levels of TDD

• Acceptance TDD (ATDD) is also called Behavior Driven Development (BDD).
• Developer TDD: Sometimes inaccurately referred to as a unit test.
