Can anyone link me a good or simple example of a multiplatform project that tests common code with common test sources on Android as an instrumented test?

[Kris Wong]

if you had common test sources, you wouldn't be able to reference the android SDK, so what would you gain from running the tests as instrumented?

[louiscad]

@Kris Wong The code being tested has actual symbols that reference Android APIs.

[Marko Mitic]

wouldn't that require android module/sourceset to be built/available for those tests to run?

[Kris Wong]

yes

[Marko Mitic]

not an expert on this, but sounds like you want to test Android module with common test sourceset included

[Kris Wong]

i would think you could create your androidTest target with a dependency on commonTest, and then adjust your android source sets so that the tests are picked up correctly

[louiscad]

I have a working multiplatform module that supports macOS, iOS and Android. The tests run fine on macOS (using macosX64Test), with the uncompleted ones failing as expected. On Android, I tried to run connectedDebugAndroidTest, but it doesn't seem to run anything as no failure is reported for the TODO() tests, nor success for the others.

[Kris Wong]

did you set android.sourceSets.androidTest.java.srcDirs?

[louiscad]

@Kris Wong I didn't. Should I put commonTest into it?

[Kris Wong]

Untitled

[Kris Wong]

that sets test, but same idea

[Kris Wong]

putting commonTest in there may work. if not then adding an androidTest and setting a source dependency should.

[louiscad]

I added that (Gradle Kotlin DSL compatible):

sourceSets.getByName("androidTest") {
        java.srcDir("src/commonTest/kotlin")
    }

and now, the tests run!
Thank you for the hint!

Will probably need to add that for androidTest/kotlin too, as you showed, so it works when I write Android specific test code.

[louiscad]

Wooops, taking back what I said, now it tells me it found no tests…

[Kris Wong]

the test runner can certainly be finicky

[louiscad]

It seems I forgot to set it up, will check again once I can reach my laptop later today.

I personally generally use this config for this kind of problems: https://github.com/algolia/instantsearch-android/blob/develop/helper/build.gradle.kts

Thank you @dany, it has been helpful reassuring me people got it working, and now I got the setup I want.
