Part 3. The test code

This part of the book covers techniques for managing and organizing unit tests and for ensuring that the quality of unit tests in real-world projects is high.

Chapter 6 first covers the role of unit testing as part of an automated build process, and follows with several techniques for organizing the different kinds of tests according to categories (speed, type) with a goal of reaching what I call the “safe green zone.” It also explains how to “grow” a test API or test infrastructure for your application.

In chapter 7, we’ll take a look at the three basic pillars of good unit tests—readability, maintainability, and trustworthiness—and look at techniques to support them. If you only read one chapter in the book, this should be it.
