ConcurrentTest fails with 'This job has not completed yet'

[lotharschulz]

Request5ConcurrentKtTest.kt fails for me with:

java.lang.IllegalStateException: This job has not completed yet

Maybe this gets fixed once

• Support completing the test coroutine from outside the test thread. Kotlin/kotlinx.coroutines#1206 is merged
  and
• runBlockingTest fails with "This job has not completed yet" Kotlin/kotlinx.coroutines#1204 is fixed and rolled out

kotlin version used: 1.3.41

You're supposed to have this error if you follow step #9 and call async with the explicit dispatcher in Request5ConcurrentKtTest.kt. Is it your case or it's different?
See "We can try calling launch with the context of Dispatchers.Default in the example above and make sure the test fails: we will get an exception saying that the job has not completed yet." in https://play.kotlinlang.org/hands-on/Introduction%20to%20Coroutines%20and%20Channels/09_Testing.
(I should emphasize that //TODO: uncomment this assertion should be done during the last step)
