# multiplatform

I found an acceptable answer how to run it from Gradle: By running test on platform module instead of on common.
Although I think it is still not supported by IntelliJ because there is no start test button on IntelliJ even though I have latest Kotlin version, and JUnit tasks are not running on common module (Error: No JUnit found).
