Question

我想用ScalatestRouteTest测试路线，如下所示：

trait MyRoutes extends Directives {

  self: Api with ExecutionContextProvider =>

  val myRoutes: Route =
    pathPrefix("api") {
      path("") {
        (get & entity(as[MyState])) {
          request => {
            complete(doSomething(request.operation))
          }
        }
      }
    }
  }
}


class RoutesSpec extends WordSpecLike with Api with ScalatestRouteTest 
  with Matchers with MyRoutes with MockitoSugar {

  "The Routes" should {

    "return status code success" in {
      Get() ~> myRoutes ~> check {
        status shouldEqual StatusCodes.Success
      }
    }
  }
}

运行测试时，我收到运行时错误：

无法运行测试MyRoutesSpec：org.jboss.netty.channel.ChannelException：无法绑定到：/127.0.0.1:2552

我不想绑定到localhost。如何实现这一目标？

解决方案是禁用远程处理和群集（这是在单独的配置文件中启用的）并使用默认提供程序。

演员远程处理和集群与正在运行的应用程序冲突（为路由测试启动）。他们选择相同的配置，因此两者都试图使用冲突的相同端口。

在特征MyRoutes中添加了以下代码以使其正常工作：

// Quick hack: use a lazy val so that actor system can "instantiate" it
// in the overridden method in ScalatestRouteTest while the constructor 
// of this class has not yet been called.
lazy val routeTestConfig =
  """
    | akka.actor.provider = "akka.actor.LocalActorRefProvider"
    | persistence.journal.plugin = "akka.persistence.journal.inmem"
  """.stripMargin

override def createActorSystem(): ActorSystem = 
  ActorSystem("RouteTest", ConfigFactory.parseString(routeTestConfig))

如何使用ScalatestRouteTest绑定到localhost
