Let us say that methodB is a call to an external service (preferable returning a Future, but that is irrelevant for the question). That external service is not valid in some test environments and therefore you want to stub it. Valid use case.
There are several ways to solve that. For example: 1) break out methodB into a class and a test implementation of that can be injected in the constructor of ActorUnderTest 2) create a subclass of ActorUnderTest and override methodB with the test behavior What am I missing?
