Question

有一个"Testing with a server"示例，说明如何使用真正的HTTP堆栈测试Play框架应用程序。

我尝试使用Play 2.5.2和Scala 2.11.7编译示例但没有成功。最初的例子是没有进口。以下是我添加到get的导入的示例代码（几乎）编译：

package models

import org.scalatestplus.play.{OneServerPerSuite, PlaySpec}
import play.api.cache.EhCacheModule
import play.api.inject.guice.GuiceApplicationBuilder
import play.api.libs.ws.WSClient
import play.api.routing.sird._
import play.api.routing._
import play.api.mvc._
import play.api.mvc.Results._

object TestExp04 {

}

class ExampleSpec extends PlaySpec with OneServerPerSuite {

  // Override app if you need an Application with other than
  // default parameters.
  implicit override lazy val app =
    new GuiceApplicationBuilder().disable[EhCacheModule].router(Router.from {
      case GET(p"/") => Action { Ok("ok") }
    }).build()

  "test server logic" in {
    val wsClient = app.injector.instanceOf[WSClient]
    val myPublicAddress =  s"localhost:$port"
    val testPaymentGatewayURL = s"http://$myPublicAddress"
    // The test payment gateway requires a callback to this server before it returns a result...
    val callbackURL = s"http://$myPublicAddress/callback"
    // await is from play.api.test.FutureAwaits
    val response = await(wsClient.url(testPaymentGatewayURL).withQueryString("callbackURL" -> callbackURL).get())

    response.status mustBe OK
  }
}

最终的编译错误是：

[error] /home/js/workspace/example/server/test/models/TestExp04.scala:32: not found: value await
[error]     val response = await(wsClient.url(testPaymentGatewayURL).withQueryString("callbackURL" -> callbackURL).get())
[error]                    ^

什么是神秘的await？我应该导入什么才能让它运行？

作为对示例作者的反馈，我想说在准备示例时请不要剥离导入。有时可能需要花费大量时间来猜测进口的正确组合。

Answer 1

实际上答案早于现有文件＆＃34; Writing functional tests with ScalaTest＆＃34;

建议导入所有助手：

import org.scalatest._
import org.scalatestplus.play._
import play.api.test._
import play.api.test.Helpers.{GET => GET_REQUEST, _}

这里的最后一次导入解决了这个问题。所以必要的进口是：

import play.api.test.Helpers.{GET => GET_REQUEST, _}
import org.scalatestplus.play.{OneServerPerSuite, PlaySpec}
import play.api.cache.EhCacheModule
import play.api.inject.guice.GuiceApplicationBuilder
import play.api.libs.ws.WSClient
import play.api.routing.sird._
import play.api.routing._
import play.api.mvc._
import play.api.mvc.Results._

Answer 2

导入play.api.test.FutureAwaits。

import play.api.test.FutureAwaits._

Answer 3

或者您也可以使用，

scala.concurrent.Await.result(scala.concurrent.Future<actually it takes super class Awaitable>, 
    scala.concurrent.Duration)

如果花费的时间超过指定的持续时间，它会为您提供一种超时测试的好方法。
