为什么测试用例抛出异常而不是发送JSON响应

问题描述

我正在测试我的代码的这一部分，当接收到异常时，它应该返回一个json响应。

val res = for(result<-service.handleTransaction(profile)) yield {
                Ok(Json.toJson(JsonResultSuccess((messagesApi("success.userSignupConfirmationEmailSent"))(langs.availables(0)))))
              }
              res.recover {
                case exception: UnconfirmedUserException => {
                  logger.trace(s"unconfirmed user")
                  Ok(Json.toJson(JsonResultSuccess((messagesApi("success.userSignupConfirmationEmailSent"))(langs.availables(0)))))
                }
                case exception => {
                  logger.trace(s"got error in handling transaction ${exception}")
                  Ok(Json.toJson(JsonResultError(exception.getMessage)))
                }

我正在测试以下代码

"test that signup request from an existing un-confirmed user should be successful" in {
  val jsonBody = Json.parse(
    """
      {
         "external-profile":{
            "email":"[e-mail]","firstname":"fn","lastname":"ln","password":"aA1!1111"
         }
      }
    """)

  val userTestEnv = new UserControllerSpecTestEnv(components=components)
  

  val exceptionInProcessing = new UnconfirmedUserException(userTestEnv.testEnv.user)
  when(userTestEnv.mockService.handleTransaction(ArgumentMatchers.any[UserProfile]))
    .thenReturn(
      Future.failed(exceptionInProcessing)
    )


  val request: Request[AnyContentAsJson] = FakeRequest("POST","ws/users/signup",Headers(("someH" -> "someV")),new AnyContentAsJson(jsonBody))
  logger.trace(s"sending sign up request ${request}")

  val response = userTestEnv.controller.signupUser(request)
  val responseBodyAsJsValue = contentAsJson(response)
  logger.trace(s"received response of sign up ${responseBodyAsJsValue}")
  val result = (responseBodyAsJsValue \ "result").get.as[String]
  val message = (responseBodyAsJsValue \ "additional-info").get.as[String]
  //responseBodyAsJsValue.\("result").
  result mustBe "success"
  message mustBe components.messagesApi("success.userSignupConfirmationEmailSent")(components.langs.availables(0))


}

上面的测试失败了，因为异常没有停止在userTestEnv.controller.signupUser(request)

我必须使用intercept来处理测试用例

"test that error is returned if processing on sign up request fails" in {

...

val receivedException = intercept[UnconfirmedUserException](await[Result](userTestEnv.controller.signupUser(request))(Timeout(Duration(5000,"millis"))))
      logger.trace(s"exception is ${receivedException}")
      receivedException.getMessage() mustBe exceptionInProcessing.getMessage
...
    }

为什么我必须使用intercept？ userTestEnv.controller.signupUser(request)是否应该处理异常并返回响应？
