사용 방법
- 설치 명령을 복사하고 자신의 에이전트 환경에 설치하기 전에 소스 패키지를 확인하세요.
- 필요한 도구, 인증 정보, 지원 환경은 원본 문서에서 확인하세요.
- 입력과 원하는 산출물을 설명하고 출처와 결과를 대조하세요.

Android Testing Strategies
This skill provides expert guidance on testing modern Android applications, inspired by "Now in Android". It covers Unit Tests, Hilt Integration Tests, and Screenshot Testing.
Testing Pyramid
- Unit Tests: Fast, isolate logic (ViewModels, Repositories).
- Integration Tests: Test interactions (Room DAOs, Retrofit vs MockWebServer).
- UI/Screenshot Tests: Verify UI correctness (Compose).
Dependencies (libs.versions.toml)
Ensure you have the right testing dependencies.
toml
[libraries]
junit4 = { module = "junit:junit", version = "4.13.2" }
kotlinx-coroutines-test = { group = "org.jetbrains.kotlinx", name = "kotlinx-coroutines-test", version.ref = "kotlinxCoroutines" }
androidx-test-ext-junit = { group = "androidx.test.ext", name = "junit", version = "1.1.5" }
espresso-core = { group = "androidx.test.espresso", name = "espresso-core", version = "3.5.1" }
compose-ui-test = { group = "androidx.compose.ui", name = "ui-test-junit4" }
hilt-android-testing = { group = "com.google.dagger", name = "hilt-android-testing", version.ref = "hilt" }
roborazzi = { group = "io.github.takahirom.roborazzi", name = "roborazzi", version.ref = "roborazzi" }Screenshot Testing with Roborazzi
Screenshot tests ensure your UI doesn't regress visually. NiA uses Roborazzi because it runs on the JVM (fast) without needing an emulator.
Setup
- Add the plugin to
libs.versions.toml:
toml
[plugins]
roborazzi = { id = "io.github.takahirom.roborazzi", version.ref = "roborazzi" }- Apply it in your module's
build.gradle.kts:
kotlin
plugins {
alias(libs.plugins.roborazzi)
}Writing a Screenshot Test
kotlin
@RunWith(AndroidJUnit4::class)
@GraphicsMode(GraphicsMode.Mode.NATIVE)
@Config(sdk = [33], qualifiers = RobolectricDeviceQualifiers.Pixel5)
class MyScreenScreenshotTest {
@get:Rule
val composeTestRule = createAndroidComposeRule<ComponentActivity>()
@Test
fun captureMyScreen() {
composeTestRule.setContent {
MyTheme {
MyScreen()
}
}
composeTestRule.onRoot()
.captureRoboImage()
}
}Hilt Testing
Use HiltAndroidRule to inject dependencies in tests.
kotlin
@HiltAndroidTest
class MyDaoTest {
@get:Rule
var hiltRule = HiltAndroidRule(this)
@Inject
lateinit var database: MyDatabase
private lateinit var dao: MyDao
@Before
fun init() {
hiltRule.inject()
dao = database.myDao()
}
// ... tests
}Running Tests
- Unit:
./gradlew test - Screenshots:
./gradlew recordRoborazziDebug(to record) /./gradlew verifyRoborazziDebug(to verify)
