UI Automator is a Google-created Android library designed for UI testing on visible elements irrespective of the running application. It works with AndroidJUnitRunner, enabling developers to write repeatable tests in Kotlin or Java. UI Automator offers rich APIs for interacting with UI elements and can be integrated seamlessly with existing JUnit test suites. A separate APK is required for testing, and Google's uiautomatorviewer tool assists in finding views and writing tests.
