Further reading
This book assumes that you already have knowledge of testing Android applications. If you would like to learn more about Android testing, you can read Chapter 9, Unit Tests and Integration Tests with JUnit, Mockito, and Espresso, from the book How to Build Android Apps with Kotlin (Packt Publishing, 2021, ISBN 9781838984113). You can also check the Android testing documentation at https://developer.android.com/training/testing.
As of the time of writing, the coroutine testing library is still marked as experimental. Before the library becomes stable later, there might be some code-breaking changes to the classes. You can check the latest version of the library on GitHub at https://github.com/Kotlin/kotlinx.coroutines/tree/master/kotlinx-coroutines-test to find the latest information about the coroutine testing library.
