Question

我正在使用scalatest测试套接字连接并打开连接是一个异步操作，以防止在异步操作完成之前完成测试我试图包装在Future中：

import io.backchat.hookup._

  it should "test connection" in {

    def doAsyncAction: Promise[T] = {
      val p = Promise[T]
      p success {
        val hookupClient = new DefaultHookupClient(HookupClientConfig(URI.create("ws://localhost:9000/get/info"))) {
          val messages = ListBuffer[String]()

          def receive = {
            case Connected =>
              println("Connected")

            case Disconnected(_) =>
              println("Disconnected")

            case JsonMessage(json) =>
              println("Json message = " + json)

            case TextMessage(text) =>
              messages += text
              println("Text message = " + text)
          }

          connect() onSuccess {

            case Success => {
                send("test")
            }
          }
        }
      }
      p
    }

    val async = doAsyncAction;

   async.future onSuccess {
      println("finished");
   };    

  }

我收到编译错误：

[error]  found   : Unit
[error]  required: T
[error]       }
[error]       ^
[error] one error found
[error] (test:compileIncremental) Compilation failed

异步代码基于：我基于How do I wait for asynchronous tasks to complete in scala?下面的

如何在Future中包含上面的测试，以便在测试完成之前运行异步操作？

更新：我不能使用来自ScalaTest的whenReady作为使用Play框架的早期版本。试图在测试中包装多个未来的调用：

  for( a <- 1 until 10){
      val fut = Future {
    val hookupClient : io.backchat.hookup.DefaultHookupClient = new DefaultHookupClient(HookupClientConfig(URI.create("ws://localhost:9000/get/info"))) {
      val messages = ListBuffer[String]()

      def receive = {
        case Connected =>
          println("Connected")

        case Disconnected(_) =>
          println("Disconnected")

        case JsonMessage(json) =>
          println("Json message = " + json)

        case TextMessage(text) =>
          messages += text
          println("Text message = " + text)
      }

      connect() onSuccess {

        case Success => {
            send("test")
        }

      }
    }
    }
    Await.result(fut, 600.seconds)
  }

但即使使用Await.result

，测试仍然在未来有时间运行之前完成

如何在未来包装最新的测试？
