Android Testing

Test infrastructure and strategy for native Android apps. Pair with kotlin-patterns for Kotlin/coroutine idioms and test-driven-development when implementing test-first.

When to activate

• Bootstrapping a testing setup on a new or legacy Android module
• Adding coverage for ViewModels, repositories, Compose screens, or navigation
• Choosing between unit, Robolectric-hosted, or on-device tests
• Introducing screenshot testing (local vs on-device)
• Diagnosing flakes in Espresso/Compose tests or emulator CI runs
