I'm trying to test a simple actor which is connecting to another remote on tcp. Here is my actor
/**
* Created by chris on 6/6/16.
*/
class Client(listener : ActorRef, actorSystem: ActorSystem) extends Actor with BitcoinSLogger {
/**
* The manager is an actor that handles the underlying low level I/O resources (selectors, channels)
* and instantiates workers for specific tasks, such as listening to incoming connections.
*/
def manager = IO(Tcp)(actorSystem)
def receive = {
case Tcp.Connect(remote,_,_,_,_) => manager ! Tcp.Connect(remote)
case Tcp.CommandFailed(_: Tcp.Connect) =>
logger.debug("Connection failed")
listener ! "connect failed"
context stop self
case c @ Tcp.Connected(remote, local) =>
logger.debug("Tcp connection to: " + remote)
logger.debug("Local: " + local)
listener ! c
val connection = sender()
connection ! Tcp.Register(self)
context become {
case data: ByteString =>
connection ! Tcp.Write(data)
case Tcp.CommandFailed(w: Tcp.Write) =>
// O/S buffer was full
listener ! "write failed"
case Tcp.Received(data) =>
listener ! data
case "close" =>
connection ! Tcp.Close
case _: Tcp.ConnectionClosed =>
listener ! "connection closed"
context stop self
}
}
def sendMessage(msg : NetworkRequest, peer : NetworkIpAddress) : Future[NetworkResponse] = ???
}
object Client {
//private case class ClientImpl(remote: InetSocketAddress, listener: ActorRef, actorSystem : ActorSystem) extends Client
def apply(listener : ActorRef, actorSystem : ActorSystem) : Props = {
Props(classOf[Client], listener, actorSystem)
}
}
here is my test case
class ClientTest extends TestKit(ActorSystem("ClientTest")) with FlatSpecLike with MustMatchers with BeforeAndAfterAll {
"Client" must "connect to a node on the bitcoin network" in {
val probe = TestProbe()
val hostName = "testnet-seed.bitcoin.schildbach.de"
val socket = new InetSocketAddress(hostName, TestNet3.port)
val peerMessageHandler = PeerMessageHandler(system)
val client = system.actorOf(Client(peerMessageHandler, system))
probe.send(client, Tcp.Connect(socket))
probe.expectMsgType[Tcp.Connected](10.seconds)
}
override def afterAll: Unit = {
TestKit.shutdownActorSystem(system)
}
}
finally, I can tell the connection is successful because my log messages are being hit:
2016-06-08 09:58:21,548 - [DEBUG] - from class org.bitcoins.spvnode.networking.Client in ClientTest-akka.actor.default-dispatcher-4 Tcp connection to: testnet-seed.bitcoin.schildbach.de:18333

however my test case is failing with this error

Seems like I am missing something simple, but I can't figure out exactly what it is.
