I would I go about to unit test this function?

fun createCoroutineScope(): CoroutineScope = CoroutineScope(SupervisorJob() + Dispatchers.Default)

So in my test I have to check if the returned CoroutineScope is using a SupervisedJob or a particular Dispatcher how do I do that??
(or any other property of the context/scope)

For instance, say I wanna write an unit test that force me to create a CoroutineScope(SupervisorJob())

@Test
fun createCoroutineScope_produce_a_supervisor_job() {
  val scope = createCoroutineScope()
  val job = scope.coroutineContext[Job]
  assertTrue(job is SupervisorJob) // can't do
}

SupervisorJob is not an interface or a class, it's a top level function. It's implementation tells me nothing about what kind of job it is or how it handle children. The implementation is private.

I cannot find a way to force me to write that code from an unit test, can anyone enlighten me?

(I've asked this in #getting-started but I realized it is better suited here + I asked it better here)
