In this chapter, you looked at some of the most common code smells as well as the most common refactorings to fix them. You saw, step by step, how to perform each of the refactorings on our project and how having a good test suite enables us to perform such refactorings with confidence. Test-driven development and refactoring go hand in hand and are invaluable tools in any developer's toolbox. In the next chapter, we will take a look at testing code interactions using mock objects.

Overview of this book
This book starts with a look at the test-driven development process, and how it is different from the traditional way of writing code. All the concepts are presented in the context of a real application that is developed in a step-by-step manner over the course of the book. While exploring the common types of smelly code, we will go back into our example project and clean up the smells that we find.
Additionally, we will use mocking to implement the parts of our example project that depend on other systems. Towards the end of the book, we'll take a look at the most common patterns and anti-patterns associated with test-driven development, including integration of test results into the development process.
