Hello Oskar, based on the two key datapoints from your email: FSM testing + at akka.testkit.CallingThreadDispatcher.dispatch(CallingThreadDispatcher.scala:208) I deduce that you are using TestActorRef (well you’re probably using TestFSMRef as suggested by the FSM docs, which also IS-A TestActorRef), which is cool for testing one actor in isolation, yet it won’t work nicely when you test interaction between actors, because it’s using the CallingThreadDispatcher. These abstractions allow to very easily test “one actor”, yet at the trade of of effectively being single threaded (sic!), which is why you’re running into deadlocks.
So while these patterns and classes are good for synchronous testing, they won’t play well if you have any kind of bigger interaction going on between actors. Please use the plain TestKit instead, like explained in the “Asynchronous Integration Testing with TestKit" section of the docs. I hope this helps, happy hakking! -- Konrad 'ktoso' Malawski hAkker @ typesafe -- >>>>>>>>>> Read the docs: http://akka.io/docs/ >>>>>>>>>> Check the FAQ: >>>>>>>>>> http://doc.akka.io/docs/akka/current/additional/faq.html >>>>>>>>>> Search the archives: https://groups.google.com/group/akka-user --- You received this message because you are subscribed to the Google Groups "Akka User List" group.
