the tests are passed, you can say that your code is complete. Interestingly, this view also happens to be one of the characteristics of test driven development (testing-driven development). Test Driven Development (TDD) is also considered to be testing first Coding (pre-coding). Test first coding is a way to take your tests one step ahead: Write your tests before you write any code. You can download it from http://xprogramming.com/xpmag/testFirstGuidelines.htm to a nice, concise summary of TDD,
