Multiplatform support

Experimental feature: iOS support

Roborazzi supports Compose Multiplatform iOS. You can use Roborazzi with Compose iOS as follows:

Gradle settings

plugins {
  kotlin("multiplatform")
  id("org.jetbrains.compose")
  id("io.github.takahirom.roborazzi")
}

kotlin {
  sourceSets {
    ...
    val appleTest by getting {
      dependencies {
        implementation(project("io.github.takahirom.roborazzi:roborazzi-compose-ios:[1.13.0 or higher]"))
        implementation(kotlin("test"))
      }
    }
  ...

Test with Roborazzi

class IosTest {
  @OptIn(ExperimentalTestApi::class)
  @Test
  fun test() {
    runComposeUiTest {
      setContent {
        MaterialTheme {
          Column {
            Button(
              modifier = Modifier.alpha(alpha),
              onClick = { }) {
              Text("Hello World")
            }
            Box(
              modifier = Modifier
                .background(Color.Red.copy(alpha = alpha), MaterialTheme.shapes.small)
                .size(100.dp),
            )
          }
        }
      }
      onRoot().captureRoboImage(this, filePath = "ios.png")
      onNodeWithText("Hello World").captureRoboImage(
        this,
        filePath = "ios_button.png"
      )
    }
  }
}

Then, you can run the Gradle tasks for iOS Support, just like you do for Android Support.

./gradlew recordRoborazzi[SourceSet]

./gradlew recordRoborazziIosSimulatorArm64
./gradlew compareRoborazziIosSimulatorArm64
./gradlew verifyRoborazziIosSimulatorArm64
...

We are migrating JVM implementation to Multiplatform implementation. So, some features are not supported yet. We are looking for contributors to help us implement these features.

Experimental feature: Compose Desktop support

Roborazzi supports Compose Desktop. You can use Roborazzi with Compose Desktop as follows:

Gradle settings

plugins {
  kotlin("multiplatform")
  id("org.jetbrains.compose")
  id("io.github.takahirom.roborazzi")
}

kotlin {
  // You can use your source set name
  jvm("desktop")
  sourceSets {
    ...
    val desktopTest by getting {
      dependencies {
        implementation(project("io.github.takahirom.roborazzi:roborazzi-compose-desktop:[1.6.0-alpha-2 or higher]"))
        implementation(kotlin("test"))
      }
    }
    ...

// Roborazzi Desktop support uses Context Receivers
    tasks.withType<KotlinCompile>().configureEach {
      kotlinOptions {
        freeCompilerArgs += "-Xcontext-receivers"
      }
    }

Test target Composable function

@Composable
fun App() {
  var text by remember { mutableStateOf("Hello, World!") }

  MaterialTheme {
    Button(
      modifier = Modifier.testTag("button"),
      onClick = {
        text = "Hello, Desktop!"
      }) {
      Text(
        style = MaterialTheme.typography.h2,
        text = text
      )
    }
  }
}

Test with Roborazzi

class MainKmpTest {
  @OptIn(ExperimentalTestApi::class)
  @Test
  fun test() = runDesktopComposeUiTest {
    setContent {
      App()
    }
    val roborazziOptions = RoborazziOptions(
      recordOptions = RoborazziOptions.RecordOptions(
        resizeScale = 0.5
      ),
      compareOptions = RoborazziOptions.CompareOptions(
        changeThreshold = 0F
      )
    )
    onRoot().captureRoboImage(roborazziOptions = roborazziOptions)

    onNodeWithTag("button").performClick()

    onRoot().captureRoboImage(roborazziOptions = roborazziOptions)
  }
}

Then, you can run the Gradle tasks for Desktop Support, just like you do for Android Support.

./gradlew recordRoborazzi[SourceSet]

./gradlew recordRoborazziDesktop
./gradlew compareRoborazziDesktop
./gradlew verifyRoborazziDesktop
...

If you use the Kotlin JVM plugin, the task will be recordRoborazzi**Jvm**.
