Writing UI tests for your Compose views
It is essential to test your code when developing Android applications, especially if your applications have many users. Furthermore, when you write tests for your code, you basically verify the functions, behavior, correctness, and versatility of the Android application. The most popular UI testing tools in Android are Espresso, UI Automator, Calabash, and Detox.
In this book, however, we will use Espresso. The most notable advantages of Espresso are as follows:
- It is easy to set up
- It has highly stable test cycles
- It supports JUnit 4
- It is made purely for Android UI testing
- It is suitable for writing black-box tests
- It supports testing activities outside the application as well
