Principles of Test Driven Development (TDD)

| Comments

TDD is a great method in software design. Traditionally, the process of TDD consists of the following steps: 1. Always write a unit test before everything else and of course il will fail 1. Write some code to pass the test, the code can be inelegant 1. Refactor the code 1. Repeat all above

Test-driven does not simply verify the correctness of the code but more important it drives the design.
