is there a way to mock the results of suspending functions using Mockito? Seems as though the argument matchers never properly working because of the manner in which the compiler desugars the tail parameter.

ie:

fun <T> OngoingStubbing<Deferred<T>>.thenDeferred(value: T) : OngoingStubbing<Deferred<T>> {
    return thenReturn( async(CommonPool) { value })
}

whenever( mockConnection.updateWithParams(sql, params)).thenDeferred(UpdateResult())

returns something i can .await() on just fine, but if I make the signature of the suspend fun updateWithParams(…): UpdateResult vs fun updatedWithParams(..): Deferred<UpdateResult>, I always get null as a result to the mocked function
