Chapter 7: Testing Kotlin Flows

In the previous chapter, we focused on understanding Kotlin Flow cancellation, learning how to make Flows cancellable, and handling the cancellation. We also learned about retrying tasks with Flows and handling completion and exceptions in your Flows.

Adding tests for the Kotlin Flows in your code is an important part of app development. Tests will ensure that the Flows we add to our projects are free of bugs or errors and that they will work as we intended. They can make developing apps easier and help you refactor and maintain your code confidently.

In this chapter, we will learn how to test Kotlin Flows in Android. First, we will understand how to set up your Android project for testing Flows. We will then proceed with creating and running tests for Kotlin Flows.

This chapter covers the following main topics:

• Setting up an Android project for testing Flows
• Testing Kotlin Flows
• Testing Flows with Turbine
