Is it possible to use kotest in a Kotlin Multiplatform Mobile project? I have included the following dependencies in the shared project:

val kotestVersion = "4.4.0"
kotlin {
    sourceSets {
        val commonTest by getting {
            dependencies {
                implementation("io.kotest:kotest-runner-junit5:$kotestVersion")
                implementation("io.kotest:kotest-assertions-core:$kotestVersion")
                implementation("io.kotest:kotest-property:$kotestVersion")
            }
        }
    }
}

but this fails when trying to build the project because there is no ios_x64 variant of kotest-runner-junit5. Android Studio fails while reloading the project trying to find kotest-runner-junit5-4.4.0-samplessources.jar and ./gradlew build explicitly fails due to the missing ios_x64 variant not found.

junit is jvm only I think. other than that, I did not try kotest in multiplatform so cannot help more

[José González Gómez]

yes, I've been googling about this and you are right, kotest-runner-junit5 is jvm only 😞

This requires native support to make framework work. You can use assertions and property testing though.

Ok, but then I guess you lose the possibility of writing tests using the styles provided by kotest and you must stick to Kotlin Test style using @Test annotation, am I right? https://kotlinlang.org/docs/mpp-run-tests.html#test-shared-code

[MiSikora]

Yes, that’s what kotest framework provides. Specification style testing.

[José González Gómez]

ok, thank you very much!

Kotest framework works on javascript too.
