In this section, we have added a feature to our project using the TDD workflow. We started with a failing test. We made the test pass. And, finally, we refactored the code to be clean. The steps you have seen here seem so simple and stupid that you may think that you could skip some of the tests and still be good. But then, it's not TDD anymore. The beauty of TDD is that the steps are so easy that you do not have to think about them. You just have to remember what the next step is.

Because the steps and the rules are so easy, you don't have to waste your brainpower thinking about what the steps actually mean. The only thing you have to remember is red, green, and refactor. As a result, you can concentrate on the difficult part: writing tests, making them pass, and improving code.
