In this Test Driven Development and refactoring course, you will learn how to apply test-driven development (TDD) and refactoring, apply the most popular open-source frameworks for TDD and use them within a popular IDE. You will learn how to think and apply test-driven design and programming and establish it as a consistent method for your development team.

You will see the value of reducing coupling in your code and learn how to break dependencies, so that tests can be run quickly in isolation. You'll learn how to apply dependency injection methods and how to create and inject alternate “test doubles”, including stubs, fakes, mocks, object factories/mothers. You will also learn to work with legacy code to “bring it under test” and apply TDD.

Finally, we will cover how refactoring is a disciplined design skill to improve the structure of code without changing its external behavior, the various “code smells” and the refactorings to clean them up and we will touch onto using an automated refactoring tool. You will also get a very brief introduction to Acceptance TDD—executable requirements with automated verification, the FIT framework and the Acceptance TDD methodology.
