android-testing

Standards for Unit Tests, UI Tests (Compose), and Hilt Integration. Use whenever writing Android test files or asking about runTest, composeTestRule, HiltAndroidRule, MockK, MainDispatcherRule, @TestInstallIn, or how to test a ViewModel/Composable/Repository in Android. (triggers: **/*Test.kt, **/*Rule.kt, @Test, runTest, composeTestRule, HiltAndroidTest, MockK, createAndroidComposeRule, MainDispatcherRule, @TestInstallIn)

Best use case

android-testing is best used when you need a repeatable AI agent workflow instead of a one-off prompt.

Standards for Unit Tests, UI Tests (Compose), and Hilt Integration. Use whenever writing Android test files or asking about runTest, composeTestRule, HiltAndroidRule, MockK, MainDispatcherRule, @TestInstallIn, or how to test a ViewModel/Composable/Repository in Android. (triggers: **/*Test.kt, **/*Rule.kt, @Test, runTest, composeTestRule, HiltAndroidTest, MockK, createAndroidComposeRule, MainDispatcherRule, @TestInstallIn)

Teams using android-testing should expect a more consistent output, faster repeated execution, less prompt rewriting.

When to use this skill

  • You want a reusable workflow that can be run more than once with consistent structure.

When not to use this skill

  • You only need a quick one-off answer and do not need a reusable workflow.
  • You cannot install or maintain the underlying files, dependencies, or repository context.

# Android Testing Standards

## **Priority: P0**

## Implementation Guidelines

### Unit Tests

- **Scope**: ViewModels, Usecases, Repositories, Utils.
- **Coroutines**: Use `runTest` (kotlinx-coroutines-test). Use `MainDispatcherRule` to mock Main dispatcher.
- **Mocking**: Use MockK.

### UI Integration Tests (Instrumentation)

- **Scope**: Composable Screens, Navigation flows.
- **Rules**: Use `createAndroidComposeRule` + Hilt (`HiltAndroidRule`).
- **Isolation**: Fake repositories in DI modules (`@TestInstallIn`).

## Anti-Patterns

- **No Real Network in Tests**: Always mock with MockK or fake repositories via @TestInstallIn.
- **No Thread.sleep**: Use IdlingResource or composeTestRule.waitUntil for async timing.
