Ok after reading the documentation which says :
*The supervisor itself is supervised by the top-level actor provided by
the ActorSystem, which has the default policy to restart in case of
all Exception cases (with the notable exceptions
of ActorInitializationException and ActorKilledException). Since the
default directive in case of a restart is to kill all children, we expected
our poor child not to survive this failure.*
So I change my code to do not override preStart, postStart and let the
top-level actor use the default strategy. Now I have this code :
case class ActorConsumer() extends Actor with ActorLogging {
var x : Int = 0
def receive = {
case y : Int =>
println("receive = " + y)
x = x + y
println("x = " + this.x)
case LetItCrash =>
sender ! x
throw new Exception
case Get => sender() ! x
}
}
class TestResumeActor
extends TestKit(ActorSystem("foo"))
with ImplicitSender
with WordSpecLike
with Matchers
with BeforeAndAfterAll {
override def afterAll() = {
TestKit.shutdownActorSystem(system)
}
"An actor consumer" must {
"get 1 even exceptions are throws" in {
val actorRef = TestActorRef[ActorConsumer]
actorRef ! 1
actorRef ! LetItCrash
expectMsg(1)
actorRef ! Get
expectMsg(1)
}
}
}
The test fails again and I didn't defined a fail over strategy like in my
first post. Also, because I'm in a test environment, do I need to do
something special when create a child of actor system ?
