The detailed example from Chapter 2, Test-Driven Development: A First Example shows what Test-Driven Development should look like in practice. As we worked through the example, we touched on a considerable number of concepts and good practices. (You might also have chosen to skip that chapter if you’re already familiar with TDD.) This chapter explores these topics in more detail, providing a bit more background and rationale behind each.
The definition of unit
The TDD cycle of red-green-refactor
The three rules of TDD
Why you should never skip observing test failure
Mind-sets for success
Mechanics for success
When you’ve worked through each of these topics, you’ll be well grounded in the process and concepts behind TDD.
