To test the code thoroughly, we need to test the code units in the context of the application. In other words, we need to test how the code units interact with other parts of the application. This type of testing is called integration testing.

In this chapter, we will mainly focus on integration testing. We will cover the following topics:

• Writing integration tests
• Testing with authentication and authorization
• Understanding code coverage ...
