It is important that Props are serializable. When constructing Props instances inside an actor one can easily close over the surrounding actor instance. To avoid this, there is a recommended practice to create Props factory methods inside the companion object that corresponds to your actor. > > > also if we define an actor within an actor > val ownerService = context.actorOf(Props[OwnerClient]) > how can it be tested ? > To make this testable you would need to either OwnerClient ActorRef or Props into the RestRouting class.
