  1. 前提の話 ・Hilt対応していると楽 ・Jetpack ComposeもAndroidViewも  相互運用も対応しているよ ComposeRuleが内部でActivityScenarioを用いているため // 内部実装 inline fun

    <reified A : ComponentActivity> createAndroidComposeRule(): AndroidComposeTestRule<ActivityScenarioRule<A>, A> { return createAndroidComposeRule(A::class.java) }
  2. 依存関係の追加 // root build.gradle buildScript { dependencies { classPath =

    "io.github.takahirom.roborazzi:roborazzi-gradle-plugin: [version]" } }
  3. 依存関係の追加 // module build.gradle apply plugin: "io.github.takahirom.roborazzi" android { testOptions

    { unitTests { includeAndroidResources = true } } } dependencies { testImplementation "androidx.test.ext:junit-ktx:[version]" testImplementation "org.robolectric:robolectric:[4.10-alpha以上]" testImplementation "io.github.takahirom.roborazzi:roborazzi:[version]" testImplementation "androidx.compose.ui:ui-test-junit4:[version]" }
  4. 依存関係の追加 // module build.gradle apply plugin: "io.github.takahirom.roborazzi" android { testOptions

    { unitTests { includeAndroidResources = true } } } dependencies { testImplementation "androidx.test.ext:junit-ktx:[version]" testImplementation "org.robolectric:robolectric:[4.10-alpha以上]" testImplementation "io.github.takahirom.roborazzi:roborazzi:[version]" testImplementation "androidx.compose.ui:ui-test-junit4:[version]" }
  5. 依存関係の追加 // module build.gradle apply plugin: "io.github.takahirom.roborazzi" android { testOptions

    { unitTests { includeAndroidResources = true } } } dependencies { testImplementation "androidx.test.ext:junit-ktx:[version]" testImplementation "org.robolectric:robolectric:[4.10-alpha以上]" testImplementation "io.github.takahirom.roborazzi:roborazzi:[version]" testImplementation "androidx.compose.ui:ui-test-junit4:[version]" }
  6. 依存関係の追加 // module build.gradle apply plugin: "io.github.takahirom.roborazzi" android { testOptions

    { unitTests { includeAndroidResources = true } } } dependencies { testImplementation "androidx.test.ext:junit-ktx:[version]" testImplementation "org.robolectric:robolectric:[4.10-alpha以上]" testImplementation "io.github.takahirom.roborazzi:roborazzi:[version]" testImplementation "androidx.compose.ui:ui-test-junit4:[version]" }
  7. 依存関係の追加 // module build.gradle apply plugin: "io.github.takahirom.roborazzi" android { testOptions

    { unitTests { includeAndroidResources = true } } } dependencies { testImplementation "androidx.test.ext:junit-ktx:[version]" testImplementation "org.robolectric:robolectric:[4.10-alpha以上]" testImplementation "io.github.takahirom.roborazzi:roborazzi:[version]" testImplementation "androidx.compose.ui:ui-test-junit4:[version]" }
  8. 依存関係の追加 // module build.gradle apply plugin: "io.github.takahirom.roborazzi" android { testOptions

    { unitTests { includeAndroidResources = true } } } dependencies { testImplementation "androidx.test.ext:junit-ktx:[version]" testImplementation "org.robolectric:robolectric:[4.10-alpha以上]" testImplementation "io.github.takahirom.roborazzi:roborazzi:[version]" testImplementation "androidx.compose.ui:ui-test-junit4:[version]" }
  9. 依存関係の追加 // module build.gradle apply plugin: "io.github.takahirom.roborazzi" android { testOptions

    { unitTests { includeAndroidResources = true } } } dependencies { testImplementation "androidx.test.ext:junit-ktx:[version]" testImplementation "org.robolectric:robolectric:[4.10-alpha以上]" testImplementation "io.github.takahirom.roborazzi:roborazzi:[version]" testImplementation "androidx.compose.ui:ui-test-junit4:[version]" }
  10. テストクラス作成 ... class BookmarkScreenShotTest { @get:Rule(order = 1) val addActivityToRobolectricRule

    = object : TestWatcher() { override fun starting(description: Description?) { super.starting(description) val appContext: Application = ApplicationProvider.getApplicationContext() val activityInfo = ActivityInfo().apply { name = ComponentActivity::class.java.name packageName = appContext.packageName } shadowOf(appContext.packageManager).addOrUpdateActivity(activityInfo) } }
  11. テストクラス作成 ... class BookmarkScreenShotTest { @get:Rule(order = 1) val addActivityToRobolectricRule

    = object : TestWatcher() { override fun starting(description: Description?) { super.starting(description) val appContext: Application = ApplicationProvider.getApplicationContext() val activityInfo = ActivityInfo().apply { name = ComponentActivity::class.java.name packageName = appContext.packageName } shadowOf(appContext.packageManager).addOrUpdateActivity(activityInfo) } } RobolectricへのActivityの登録を行う
  12. テストクラス作成 ... class BookmarkScreenShotTest { @get:Rule(order = 1) val addActivityToRobolectricRule

    = object : TestWatcher() { override fun starting(description: Description?) { super.starting(description) val appContext: Application = ApplicationProvider.getApplicationContext() val activityInfo = ActivityInfo().apply { name = ComponentActivity::class.java.name packageName = appContext.packageName } shadowOf(appContext.packageManager).addOrUpdateActivity(activityInfo) } } 登録できてないとエラーが発生する java.lang.RuntimeException: Unable to resolve activity for Intent...
  13. テストクラス作成 ... class BookmarkScreenShotTest { ... @get:Rule(order = 2) val

    composeRule = createComposeRule() @Test @Config(sdk = [33], qualifiers = RobolectricDeviceQualifiers.Pixel7) fun captureSampleScreen() { composeRule.setContent { SampleTheme { SampleScreen(...) } } composeRule.onNode(isRoot()).captureRoboImage() }
  14. テストクラス作成 ... class BookmarkScreenShotTest { ... @get:Rule(order = 2) val

    composeRule = createComposeRule() @Test @Config(sdk = [33], qualifiers = RobolectricDeviceQualifiers.Pixel7) fun captureSampleScreen() { composeRule.setContent { SampleTheme { SampleScreen(...) } } composeRule.onNode(isRoot()).captureRoboImage() } createComopseRuleを呼び出す
  15. テストクラス作成 ... class BookmarkScreenShotTest { ... @get:Rule(order = 2) val

    composeRule = createComposeRule() @Test @Config(sdk = [33], qualifiers = RobolectricDeviceQualifiers.Pixel7) fun captureSampleScreen() { composeRule.setContent { SampleTheme { SampleScreen(...) } } composeRule.onNode(isRoot()).captureRoboImage() } スクショする端末のSDKと機種を指定
  16. テストクラス作成 ... class BookmarkScreenShotTest { ... @get:Rule(order = 2) val

    composeRule = createComposeRule() @Test @Config(sdk = [33], qualifiers = RobolectricDeviceQualifiers.Pixel7) fun captureSampleScreen() { composeRule.setContent { SampleTheme { SampleScreen(...) } } composeRule.onNode(isRoot()).captureRoboImage() } Composeを起動させる
  17. テストクラス作成 ... class BookmarkScreenShotTest { ... @get:Rule(order = 2) val

    composeRule = createComposeRule() @Test @Config(sdk = [33], qualifiers = RobolectricDeviceQualifiers.Pixel7) fun captureSampleScreen() { composeRule.setContent { SampleTheme { SampleScreen(...) } } composeRule.onNode(isRoot()).captureRoboImage() } captureRoboImageでスクショを撮る
