Hi, I have seen a couple of issues around the test dispatcher but I can’t quite tell if this is the same error.

I am using
```StandardTestDispatcher(testCoroutineScheduler))```
to inject a dispatcher into a subject under test.

This works fine on android/java but when i run it on iosArmSimulator64 I get the error `Dispatcher is not a TestDispatcher`. I am using the `BehaviorSpec`.

Is test scheduler available on ios ?  Is there some set up I am missing?

I think the problem is the KotestConfig is not being found / read where we have `coroutineTestScope = true`. I put that config on each test scope and it worked.

So you have that set in a project config?

i’m working on reproducing in a vanilla app

We have

```public class KotestConfig : AbstractProjectConfig() {
    override val isolationMode: IsolationMode = IsolationMode.InstancePerRoot
    override val coroutineTestScope: Boolean = true
    override val invocationTimeout: Duration = 30.seconds
    override val timeout: Duration = 30.seconds
    override val projectTimeout: Duration = 5.minutes
}```
but its in a module that we depend on in commonTest

```        commonTest.dependencies {
            implementation(projects.coreTestConfigAndFakes)
            implementation(catalog.kotlin.coroutinesTest)
        }```

The scanner probably won't find it unless it's alongside the tests

I'd have to check how ksp finds the classes

Should I raise it as a bug or do you want to get back to me first?

its fine if you close it as won’t fix just want to track it

If you can make an issue to track that would be great
