I’m following what KaMPKit wrote in this stackoverflow thread to test my sqldelight queries https://stackoverflow.com/questions/65663436/how-to-write-unit-tests-for-sqldelight-on-kmm
My test succeeds in android but I get kotlin.IllegalStateException: There is no event loop. Use runBlocking { ... } to start one. when running the same test for ios.
this is my BaseTest class in iosTest

actual abstract class BaseTest {
    @OptIn(DelicateCoroutinesApi::class)
    actual fun <T> runTest(block: suspend CoroutineScope.() -> T) {
        var error: Throwable? = null
        GlobalScope.launch(Dispatchers.Main) {
            try {
                block()
            } catch (t: Throwable) {
                error = t
            } finally {
                CFRunLoopStop(CFRunLoopGetCurrent())
            }
        }
        CFRunLoopRun()
        error?.also { throw it }
    }
}

I just copied what they have. Any idea what I’m doing wrong?

Don't use Dispatchers.Main in tests

[jean]

Thanks 🙂 Using Dispatchers.Default instead seems to work

you need to use the multithreaded version of coroutines, e.g. 1.5.1-native-mt
