Testing Android ViewModels and data flows requires isolated unit tests using JUnit4 and kotlinx-coroutines-test. This approach validates business logic quickly by executing synchronous coroutine operations and verifying state transitions within repositories and ViewModels.

Yes, Hilt supports Android integration testing through the hilt-android-testing dependency. It enables automated dependency injection for your tests, allowing you to verify interactions between Room DAOs, Retrofit networks, and data flows reproducibly.

Screenshot testing with Roborazzi is the best way to verify Compose UI rendering across screen sizes. It captures and compares UI images automatically, ensuring visual correctness for Compose-based interfaces during typical development and CI workflows.

Yes, this strategy explicitly covers unit tests for isolated ViewModel validation and integration tests for component interactions like Room and Retrofit. It combines these with UI screenshot verification to ensure comprehensive code quality and reliability.

You need Roborazzi when performing UI and screenshot testing for modern Compose-based Android applications. It automates visual verification by rendering UI components to images, ensuring visual correctness across different screen sizes in your CI workflows.
