At the end of each test or test suite, you stop the actor system that was
running, usually using TestKit.shutdownActorSystem, this method takes a
timeout, if it hasn't manage to terminate the actor system before this
timeout the call fail with the error message you describe.
All actors are stopped when before the ActorSystem shutdown completes. If
there is an actor blocking or simply not completing the processing of a
message (let's say it does a while(true) { ... } for example, this will
hinder the shutdown. You can figure out exactly what in your code is
blocking/hindering actor shutdown by taking a thread dump, you should be
able to see your own logic in one of the stack traces hinting you towards
what is wrong.
