使用编译时DI时,Play 2.4.6中的功能测试

我正在使用Play 2.4.6编译时依赖注入和ScalaTest.控制器的构造函数有很少的参数,在ApplicationLoader中我创建它.这是代码:

class BootstrapLoader extends ApplicationLoader {
  def load(context: Context) = {
    new AppComponents(context).application
  }
}

class AppComponents(context: Context) extends BuiltInComponentsFromContext(context) with NingWSComponents {
  lazy val router = new Routes(httpErrorHandler, authenticationController, applicationController, assets)
  lazy val applicationController = new controllers.Application()
  lazy val authenticationController = new controllers.Authentication()(configuration, wsApi.client)
  lazy val assets = new controllers.Assets(httpErrorHandler)
}

class Authentication(implicit configuration: Configuration, val ws: WSClient) extends Controller {
  def login = Action { implicit request =>
    Unauthorized(s"${redirectUrl}")
  }
}

class AuthenticationSpec extends PlaySpec with OneAppPerSuite {

  implicit val configuration: Configuration = app.configuration
  implicit val wsClient: WSClient = WS.client(app)

  "when user not logged-in" should {
    "return Status code Unauthorized(401) with redirect url" in  {
      1 mustEqual 2
    }
  }
}

当我运行测试时,我收到以下错误:

[info] Exception encountered when attempting to run a suite with class name: controllers.AuthenticationSpec *** ABORTED ***
[info]   com.google.inject.ProvisionException: Unable to provision, see the following errors:

FakeApplication使用GuiceApplicationBuilder,当然不起作用.

我该怎么做才能进行这样的测试？

谢谢
