A modern programming language that makes developers happier.

kotlinlang

Somewhat related (and this is very likely issue on my side but just in case anything jumps out)....I have a unit test in `commonTest` in KMM module using new `runTest` provided in Kotlinx Coroutines 1.6 to test some code that uses apollo...it runs fine for android, jvm but get issue when running for iOS .:thread:

I'm running the test in <https://github.com/joreilly/StarWars/blob/main/shared/src/commonTest/kotlin/dev/johnoreilly/starwars/shared/StarWarsRepositoryTest.kt>

Screenshot 2021-12-29 at 13.54.05.png

as initial test it's doing following right now

```val people = repo.people.first()
assertTrue(people.isNotEmpty())
println(people)```
testing the following flow that's in repository class

```val people = apolloClient.query(GetAllPeopleQuery()).watch().map {
    it.dataAssertNoErrors.allPeople.people.mapNotNull { it?.personFragment?.mapToModel() }
}```

when I run for iOS I'm getting following due it seems to `first()` above never returning

```UncompletedCoroutinesError: After waiting for 60000 ms, the test coroutine is not completing, there were active child jobs```

I suspect it might be some issue related to various dispatchers etc used but haven't been able to isolate it yet

If I replace `people` flow above with some dummy `flow { emit() }` for example it works fine

The apollo code always resumes coroutines on the main thread after a network call or database on iOS. Therefore it's important to have a main loop (as in dispatch_main) running

Apollo has its own `runTest` method that does this in `apollo-testing-support`

Ultimately, this should all go away when switching to the new memory model

pulling in the one from `apollo-testing-support` for now then....confirmed tests runs for iOS as well now <https://github.com/joreilly/StarWars/pull/20>
