From what I understood, runBlocking is not available for iOS, but what’s the proper way to unit test suspend functions on iOS Simulator then?

[Jurriaan Mous]

With runBlocking. It should be available. It is not available in common though. I made an expect actual for that:

expect fun runSuspendingTest(block: suspend () -> Unit)

import kotlinx.coroutines.runBlocking

actual fun runSuspendingTest(block: suspend () -> Unit) = runBlocking { block() }

Usage:

@Test
    fun test() = runSuspendingTest {
        // Suspending tests here
    }

What I’ve heard from JetBrains team in the context of working with ktor HttpClient:

You can’t use runBlocking with ios client engine for now: the request is scheduled in the main queue.

So yes, it’s available, but not compatible with HttpClient…

Ah ok. I don't use it yet so I don't have the answer. Good to know the current limitation!

You can use it like this:

I found your code yesterday. It works like 50% of the time for me. Sometimes one of the assertions fails and the tests hang, sometimes it succeeds. I leave it for now at that, but wait for an official solution.
