I’d like to add that there is value in coupling the tests: if you always use 
fresh probes then you won’t notice if unexpected messages trickle out of a test 
case after it finishes. Our Akka test suite is constructed such that each test 
case consumes all the expected messages, which means that extraneous ones will 
fail a later test case and thus be noticed.

Of course this is somewhat circumstantial, doing this as a side-effect of 
grouping tests together. An alternative would be to teach the testing 
frameworks to watch out for asynchronous failures on different threads, but 
that is in general not a simple thing to do.

Regards,

Roland
