Thanks Martynas, currently I am trying the TestActorRef approach which
works.

Hi Kostas,
I see two ways in approaching this. First, you could use TestActorRef
to test the insides
<http://doc.akka.io/docs/akka/2.3.11/scala/testing.html#Synchronous_Unit_Testing_with_TestActorRef>
of your actor. In this way you could reach to the underlying instance
of your actor and test each Receive block independently in a unit test
fashion.
Now another approach is akin to integration testing when you test an
actor by sending and expecting messages. In such case the actor either
has to signal to the outside by a message that it has become a
particular actor, or you have to periodically send messages and wait
for a response for a finite period of time.

Hi,
Currently my actor becomes ready when it receives a msg :
class MyActor {
private val mediator =
DistributedPubSubExtension(context.system).mediator
mediator ! Subscribe(Subscriptions.Index, self)
...
override def receive = {
case SubscribeAck(Subscribe(Subscriptions.Index, None,
self)) =>
context become ready
}
def ready =
createPart.receive orElse
retrievePart.receive
}
This creates problems in test cases, when I send a msg to my actor:
myActor ! Create(...) // this is received before SubscribeAck and
hence it is ignored
My temp solution is to sleep a bit after creating an actor so that
I give an opportunity to the mediator to send the SubscribeAck:
val indexActor =
system.actorOf(Props(IndexActor.empty(IntKey, StringValue,
cluster.ref)))
// TODO: replace this with something better. This is
required so that the actor becomes ready
Thread.sleep(5)
Is there a better solution?
Thanks
