刚才有人给我留言，说[url=http://charon.blogdriver.com/charon/132572.html ]Test Drive != Test First[/url]，让我差点晕倒。

无话好说，就贴一段Kent Beck对TDD的定义：

Test-driven development (TDD) (Beck 2003;  Astels 2003), is an evolutionary approach to development which combines test-first development where you write a test before you write just enough production code to fulfill that test and  refactoring.  

如果有人想给TDD重新定义的话，最好先通知大家一声。
