Real Unit Testing with Test Doubles
A unit test differentiates itself from other test categories by using test doubles; actually, you would rarely see a unit test without a test double.
There is a lot of confusion on the web about what that means. My aim in this chapter is to clarify this term so that you can use it in the right context and give you as many explained examples of the topic so you feel confident in selecting the right test double for the test at hand.
In this chapter, we will:
- Explain the concepts and usage of test doubles
- Discuss more testing categories
By the end of the chapter, you will understand what is special about unit testing and will be able to use test doubles to start writing realistic unit tests.
