I'm trying to unit test my use cases coroutines using *mockk* but I don't know how to do the verification of a lambda. I have the gists of the test and the base class. Anyone has experience with this kind of testing?

First of all I do not like the idea of tying your use case classes to your threading implementation. In my experience it causes undue complication to the code because of it being a leaky abstraction.

For the full reasoning please take the time to watch this video by Mark Seeman:

Even if you do not agree it's good to get other opinions.

TLDR: Inject behavior (AKA the UseCase class) into the asynchronous function.
