Explanation / Answer

Test-driven design (TDD) (Beck2003; Astels2003), is an evolutionary approach todevelopment which combines test-first development where you write atest before you write just enough production code to fulfill thattest and refactoring.  What is the primary goal of TDD? One view is the goal ofTDD is specification and not validation (Martin,Newkirk, and Kess 2003). In other words,it’s one way to think through your design before your writeyour functional code. Another view is that TDD is aprogramming technique. see more here: http://www.agiledata.org/essays/tdd.html and here: http://en.wikipedia.org/wiki/Test-driven_development
