Ich habe die Frage Das ist mein Server https://github.com/vladimirkozhaev/reverse-str Das ist mein Klient ist https://github.com/vladimirkozhaev/string-reverse-client Wenn ich den Server mit sbt Fahrbefehl ausführen dannAkka + scala Reverse-Server-Fehler
Paket org.reversestr.client
folgenden Test durchgeführtimport org.scalatest.concurrent.PatienceConfiguration.Timeout
import org.scalatest.{FunSpecLike, Matchers}
import org.scalatest.concurrent.ScalaFutures
import scala.concurrent.duration._
class RClientIntegrationSpec extends FunSpecLike with Matchers with ScalaFutures {
val client:RClient = new RClient("127.0.0.1:2552")
describe("reverse str Scala Client") {
describe("set method") {
it("should set a value") {
whenReady(client.setStr("123"), Timeout(1 second)) {
r => r shouldBe "321"
}
}
}
}
}
Haben Sie diese seltsame Fehlermeldung Wo liege ich falsch?
