Attempting to test Resume Directive

I am struggling to get this test to work. The first test scenario works, basically I am attempting to assert the write is called properly on db instance. Second and third case does not work. For the second case, exception is never caught by the supervisor. Third case is similar. I asked question on StackOverflow: http://stackoverflow.com/questions/25976345/akka-testing-supervisor-error-handling. Do you have any suggestion or am I on the right track? Thanks!
You are trying to test two different actors in one spec. '1' is testing the supervisor and '2' is testing the child. '1' is the only appropriate test for this spec.

We cannot refactor this to accept an ActorRef as a child. The `supervisorStrategy` is only used for children and the definition of a child is an actor created from within the supervisor using `context.actorOf`.You cannot inject children by definition.
