Hello
There are runBlocking and runBlockingTest builders in the "jvmTest" sourceSet.
Is it possible to write Unit tests using suspend functions in "jsTest"?
If yes - please give a link to examples?
If not - is planned in future?
Thanks!

Have you tried just marking the test method suspend ?

[Dima Avdeev]

Let's try:

@Test
suspend fun sampleTestOnJs() {
...
}

Output: Unsupported [suspend test functions]

[Dima Avdeev]

In JVM we can do this:

@Test
fun sampleTestOnJvm() {
    runBlocking {
        ...
    }
}

I actually thought it was suppose to be supported but seems not https://youtrack.jetbrains.com/issue/KT-22228

There is a sample in the comment: https://youtrack.jetbrains.com/issue/KT-22228#focus=streamItem-27-3964713.0-0

Basically you convert a suspend lambda to Promise and return it from the test.

Yes, @Test suspend fun test... was supposed to be supported, but that never happened unfortunately
