Kotlin/Multiplatform how to see stdout/stderr of tests on console?

Question

I tried setting the following for all the tasks having type Test as follows:

tasks.withType<Test> {
    testLogging {
        exceptionFormat = TestExceptionFormat.FULL
        showStandardStreams = true
        showStackTraces = true
    }
}

But the setting only applies to the JVM, but not all the targets on Kolin/Multiplatform.

How to direct/enable the standard out and standard error streams to output in the console?

Only the exception name is printed in the console (not even the exception message):

> Task :keyboard:linuxX64Test FAILED

com.github.animeshz.keyboard.NativeKeyboardHandlerTest.Caps lock key should be toggled when KeyDown event is triggered FAILED
    kotlin.IllegalStateException

com.github.animeshz.keyboard.NativeKeyboardHandlerTest.Test send and receive event FAILED
    kotlin.IllegalStateException

I don't know how to debug this now, when I'm testing the library on multiple targets (on a VM) when I don't have (want to install) Intellij there.

You need to define testLogging for each test task type as you are currently only defining it for JVM, something similar to this should work in your build.gradle.kts:

tasks {


        val jvmTest by getting(Test::class) {
            testLogging {
                events("PASSED", "FAILED", "SKIPPED")
                exceptionFormat = TestExceptionFormat.FULL
                showStandardStreams = true
                showStackTraces = true
            }
        }

        val linuxTest by getting(KotlinNativeTest::class) {

            testLogging {
                events("PASSED", "FAILED", "SKIPPED")
                exceptionFormat = TestExceptionFormat.FULL
                showStandardStreams = true
                showStackTraces = true
            }
        }

        val jsNodeTest by getting(KotlinJsTest::class) {
            testLogging {
                events("PASSED", "FAILED", "SKIPPED")
                exceptionFormat = TestExceptionFormat.FULL
                showStandardStreams = true
                showStackTraces = true
            }
        }
