Depending on the JDK used, in kmm either iosX64Test or iosSimulatorArm64Test works and the other is SKIPPED. Can I check if the currently used JDK is arm64 or x64 compatible in gradle script to run the right test task?

[ephemient]

just try to run all the tests. the ones that can't run on the current platform are automatically disabled

[Michal Klimczak]

it's true, but they both have to compile and that takes a lot of time. wanted to automate that (also this behavior is far from obvious so a new gradle task would be more discoverable than a comment in project's readme)

[ephemient]

you could probably do something like

tasks.register("allEnabledNativeTests") {
    dependsOn(tasks.withType<KotlinNativeTest>().matching { it.enabled })
}

[Michal Klimczak]

oh, so there's enabled flag. looks sweet, I'll try that, thank you!

[Michal Klimczak]

It works beautifully in selecting the right test task and running it, thank you very much! The only thing that lacks is test output - it doesn't pass through any info about the test result and ide doesn't recognize it.

[ephemient]

the Kotlin Gradle Plugin goes through some hacks to get that to work, https://github.com/JetBrains/kotlin/blob/master/libraries/tools/kotlin-gradle-plug[…]jetbrains/kotlin/gradle/testing/internal/KotlinTestsRegistry.kt → https://github.com/JetBrains/kotlin/blob/master/libraries/tools/kotlin-gradle-plug[…]kotlin/org/jetbrains/kotlin/gradle/testing/internal/ultimate.kt

[ephemient]

for local development, I'd just locally patch the build scripts to avoid registering the targets you don't want rather than try to replicate and maintain that

[Michal Klimczak]

Yeah, I thought it's maybe a matter of intercepting whatever the original task outputs and passing it through to the output of my custom task. Apparently not that easy

[Michal Klimczak]

this custom task will be used by the CI as an additional check to the jvm test suite which is a superset, so I think I have more than enough here 🙂
