I'm trying to set up some tests with suspend functions, It works fine on JVM but I'm curious what people are doing for JS and native?

runBlocking exists in native. For JS, you can wrap the suspend function into a promise.

#kotest works on JVM and JS and everything is suspending by default (but I don’t think Native is supported yet)

[dan.the.man]

I have

actual fun runTest(block: suspend (scope : CoroutineScope) -> Unit):
        dynamic = GlobalScope.promise { block(this) }

for my JS implementation but the test still just completes instead of failing like i'd expect. On JVM this is just runBlocking{} and it all performs how you would expect.

What am I doing wrong?

[louiscad]

@dan.the.man I don't think you should have it with the actual modifier.

[dan.the.man]

In my common module I have

expect fun runTest(block: suspend (scope : CoroutineScope) -> Unit)

[dan.the.man]

To try and test common code on each platform

[louiscad]

Yes I understand, but `expect`/`actual` is for identical signatures. It's not the case here as the JS one returns a promise in form of dynamic (Not sure why you return dynamic BTW)

Here's the issue you want to follow and look for regarding workarounds @dan.the.man: https://youtrack.jetbrains.com/issue/KT-22228

I'm not entirely sure either, I've only done jvm kotlin before
