After moving some previously working test code to its own testing-support module, I'm getting an error: Unresolved reference: BeforeTest for kotlin.test.BeforeTest during the :testing-support:compileKotlinJvm task. I've added api(kotlin("test")) to :testing-support:commonMain dependencies. The code works for macOS and iOS, but not JVM or Android targets. The IDE doesn't show an error, just during the compile task. Any idea why this doesn't work?

you need to choose a jvm implementation among kotlin-test-junit kotlin-test-junit5 kotlin-test-testng

Ah, that's right, thanks! I tried adding junit itself, but not the kotlin-test implementation. This must default to something in the jvmTest source set somehow, as I forgot it there before moving to its own module. It's working now after adding api(kotlin("test-junit")).

it defaults to junit4 tests but that only works in the test source set, which means your separate module needs to handle it https://kotlinlang.org/docs/gradle-configure-project.html#set-dependencies-on-test-libraries

[Jeff Lockhart]

That makes sense, thanks.
