Part 2. Core techniques

Having covered the basics in previous chapters, I’ll now introduce the core testing and refactoring techniques necessary for writing tests in the real world.

In chapter 3, we’ll begin by examining stubs and how they help break dependencies. We’ll go over refactoring techniques that make code more testable, and you’ll learn about seams in the process.

In chapter 4, we’ll move on to mock objects and interaction testing and look at how mock objects differ from stubs, and we’ll explore the concept of fakes.

In chapter 5, we’ll look at isolation frameworks (also known as mocking frameworks) and how they solve some of the repetitive coding involved in handwritten mocks and stubs. Chapter 6 also compares the leading isolation frameworks in .NET and uses FakeItEasy for examples, showing its API in common use cases.
