Hello all! Could you let me a bit more details about running kotest in multiplatform project (JVM + JS)? According documentation I added into build.gradle.kts:

val commonTest by getting {
            dependencies {
                implementation(kotlin("test-common"))
                implementation(kotlin("test-annotations-common"))
                implementation("io.kotest:kotest-framework-engine:$kotestVersion") //<< This dependency
            }
        }

And wrote test:

class OperationResultSerializationTest: FunSpec({

    val json = Json {
        serializersModule = SerializersModule {
            polymorphic(Any::class) {
                subclass(TestPayload::class)
            }
        }
    }

    test("success action result should be serialized and deserialized") {
        val actionSuccessJson = json.encodeToString<ActionResult>(ActionSuccess)
        val actionSuccessDeserialized = json.decodeFromString<ActionResult>(actionSuccessJson)

        actionSuccessDeserialized shouldBe null //<<Should FAIL here (intentionally)
    }
})

But when I run it using gradlew check I get in IDEA just row:

You should be able to use the gradle tasks to execute "check"

Are you using IR backend for JS?

Yes, I use IR compiler, because legacy have bug in serialization

Oh. Thank you.

@Ashish Kumar Joy can you try 4.5 final ?

sure

and if that fails, I'm doing a PR atm for kotlin 1.5 which might help

Same result with 4.5.0

Still same result with the above snapshot version

hmmm how weird

No idea why js test are not getting register/discovered.

I wonder if in IR js they changed the way the compiler discovers tests
