Testing a UI created with Compose is different from testing a View-based UI. Testing Composable UIs to verify the correct behaviour of your Compose code and improving the app’s quality by catching errors early in the development process is quite crucial for a robust user experience. Compose provides a set of testing APIs to find elements, verify their attributes and perform user actions. In this course, explore how to set up the test environment, where to put the test classes and how to write & run test cases. You'll explore how we can access Composables within a test environment, perform operations on them and can validate the test results. For reference, we'll create a profile editing screen in which we'll write tests for different UI validations before saving the profile. At the end of this course, you'll be able to write and run tests for your Composables in Android.
