Akka TestKit fails...

[Objekt Werks]

Hey, Bill

Thanks for all your hard work on ScalaTest. It's all I use.

So, I upgraded to 3.0.0-M10 from 2.2.5. And all my Akka tests passed. Oddly enough, my single Akka TestKit test failed.:)

Here's the test:

Enter code here...package akka

import akka.actor._
import akka.testkit.{ImplicitSender, TestKit}
import org.scalatest.{BeforeAndAfterAll, Matchers, WordSpecLike}

import scala.concurrent.Await
import scala.concurrent.duration._

class Ping extends Actor with ActorLogging {
  def receive = {
    case ping: String => log.info(ping); sender ! ping
    case _ => log.info("Ping received an invalid message.")
  }
}

class TestKitTest extends TestKit(ActorSystem("testkit", Conf.config))
  with ImplicitSender
  with WordSpecLike
  with Matchers
  with BeforeAndAfterAll {
  val ping: ActorRef = system.actorOf(Props[Ping], name = "ping")

  override protected def afterAll(): Unit = {
    Await.result(system.terminate(), 1 second)
  }

  "Ping actor" should {
    "reply with an identical message" in {
      within(2 seconds) {
        ping ! "ping"
        expectMsg("ping")
      }
    }
  }
}

it blow up on line 32: expectMsg("ping"). Conf just load a named Akka config file.

Best Regards, Mike

Hi Mike,

Thanks for the report. Someone reported a similar issue a few days ago, so we went back to the drawing board. The implicit conversion method we used in M10 won't work. It has already been ejected. I'll have a new milestone release soon with an approach that has a bit more API surface area, but won't cause this kind of problem.

Bill
