Hello,
Akka docs say:

But when testing one of the actors I get InvalidActorNameException even
after expectTerminated was successful. This is the test:
"stop self when finished" in {
val fetcher = system.actorOf(EventFetcherActor.props(eventId), "name1")
watch(fetcher)
// interact with the actor, it will call context.stop(self) after
interaction
expectTerminated(fetcher)
system.actorOf(EventFetcherActor.props(eventId), "name1") //Exception
thrown
}
90% of times I run it, the test passes. But what is the reason of failures?
Can it be related to the fact that it's unit test?
This is exception message I get:
actor name [name1] is not unique!
akka.actor.InvalidActorNameException: actor name [name1] is not unique!
