Akka test for deadletters

How can I make assertion against deadletters in Akka while testing? I have an actor which can switch behaviours (using become) and deals with some Futures dispatched using separate Dispatcher. In some certain condition it should simply reject other messages. Those correctly go to a deadletters, however I would like to try to assert for them (or lack of). How can I do this?

Dead letters are delivered using the event stream so you can subscribe to that in your tests with a probe and verify messages or lack of messages

system.eventStream.subscribe(probe, classOf[DeadLetter])
