Re: [akka-user] unit testing persistence recovery
Hello Tim!
The PersistentActor is not the guy with the lock, it’s the (LevelDB)
journal.
You only need 1 actor system running (and one journal) to test what you
want, example:
class MyPersistentActor(override val persistenceId: String) extends
PersistentActor {
// … persist events, handle recovery...
}
// test:
val act = sys.actorOf(Props[MyPersistentActor](“id-1212"))
act ! “persist-me-1”
act ! “persist-me-2” // persist(){} those
val act2 = sys.actorOf(Props[MyPersistentActor](“id-1212”))
// recovery kicks in, because they get the same persistenceId
act ! “what’s the last persist-me-### you got?”
expectMsg(“persist-me-2”) // because recovery
I hope this helps, happy hakking!

Re: [akka-user] unit testing persistence recovery
Thanks Ok - just to make sure I've got this straight. If I start a new PeristentActor with the same id as an existing one it will just start in recovery mode regardless of the other one - right?

Re: [akka-user] unit testing persistence recovery
If I start a new PeristentActor with the same id as an existing one it will just start in recovery mode regardless of the other one - right? Yes, it'll recover that persistent state. The other thing you could do is to act ! “boom” it to make it restart, which also triggers the replay.
