Question: With Test Driven Development or Test Driven Design, the first unit test you write for a method should FAIL, since you haven't written any code

With Test Driven Development or Test Driven Design, the first unit test you write for a method should FAIL, since you haven't written any code for the method. After this failing test you write code to just pass the test that failed. Once a test passes, you can clean up the code in the method as necessary. This TDD process is sometimes called "Red, Green, Refactor".
