UI Automator
UI Automator is a testing framework provided by Google for Android that allows developers to write automated UI tests for Android applications. It enables interaction with UI elements across different apps and system interfaces, making it suitable for functional and integration testing. The framework works by accessing the Android UI without requiring knowledge of the app's internal implementation.
Developers should learn UI Automator when they need to perform cross-app UI testing on Android, such as testing interactions between multiple applications or with system UI components. It is particularly useful for automation engineers and QA developers working on Android apps that require end-to-end testing scenarios, like testing notifications, settings, or third-party app integrations.
