To build an Android testing strategy, analyze existing test setups including dependency injection, UI architecture, and coverage approaches. Configure appropriate frameworks for unit tests, UI tests, screenshot tests, and end-to-end testing workflows to improve automation coverage across business logic and user journeys.

Set up Android test infrastructure by configuring testing libraries based on project needs. Configure JUnit for unit tests, Hilt for dependency injection testing, Compose testing for UI, Espresso for interactions, Robolectric for local execution, Dropshots for screenshots, and Jacoco for coverage tooling.

Screenshot testing with Dropshots captures and compares UI rendering states during test execution. It integrates into your testing strategy by verifying visual regressions across Android user journeys, ensuring UI components and Compose interfaces render consistently across different device configurations and code changes.

Yes, Robolectric and Espresso can be configured for Android testing. Robolectric runs unit tests locally without an emulator, while Espresso handles UI interactions. Both integrate into a comprehensive test infrastructure alongside JUnit, Hilt, Compose testing, and Jacoco coverage tooling.

Hilt testing configuration is required when your Android app uses Hilt for dependency injection. It allows you to inject test dependencies and mock modules during test execution, which is essential for isolating business logic and creating reliable unit tests and UI tests.

Android test coverage requires Jacoco to measure code execution across business logic and UI workflows. Test harness patterns structure test execution for database tests and end-to-end testing, ensuring reliable automation coverage and accurate reporting of tested versus untested code paths.
