Anyone know how to make `androidTestImplementation` compile in a compose multiplatform project?

Anyone know how to make androidTestImplementation compile in a compose multiplatform project?

[jw]

the instrumented tests are their own source set

[jw]

so you don't add it to androidMain, you add it to androidInstrumentedTest or something as an implementation dependency

seems like this works. need to work through some other compilation issues before a concrete yes/no. but that works. thanks jake

androidNativeTest.dependencies {
    implementation("androidx.compose.ui:ui-test-junit4")
}

yeah i believe "androidNative" is the aggregate source set for the android native targets that you probably aren't using

[Jeff Lockhart]

It is androidInstrumentedTest that you want. Note that by default, this source set is not connected to the commonTest source set tree, so it won't run common code. If you want it to be, then you can specify the source set tree like this:

kotlin {
    @OptIn(ExperimentalKotlinGradlePluginApi::class)
    androidTarget {
        instrumentedTestVariant.sourceSetTree.set(KotlinSourceSetTree.test)
        unitTestVariant.sourceSetTree.set(KotlinSourceSetTree.unitTest)
    }
}

This connects the androidInstrumentedTest source set to the commonTest tree, and disconnects the androidUnitTest source set from it, assuming you want to run your common tests as instrumented tests and not unit tests.

Going to go out on a whim and ask here even though it's arguably a different question.

I have free and paid build variants.

in android {} i have

productFlavors {
  create("free") {
    dimension = "stage"
    applicationIdSuffix = ".free"
  }

  create("paid") { dimension = "stage" }
}

then in kotlin {}
i have

sourceSets {
    sourceSets.invokeWhenCreated("androidFree") {
    }
    sourceSets.invokeWhenCreated("androidPaid") {
    }

I updated my dirs from /free and /paid to androidFree and androidPaid.

does that all seem correct?
