使用Scalamock模拟播放WSRequestHolder get方法

Question

val responseFuture = wsClient.url(url).withQueryString(params: _*).get()

val mockHttpClient = mock[THttpClient]

val expectedUrl = "some url"
val mockRequestHolder = mock[WSRequestHolder]
inSequence {
  (mockHttpClient.url _).expects(expectedUrl).returns(mockRequestHolder)
  (mockRequestHolder.withQueryString _).expects(where {
    (parameters: Seq[(String, String)]) => {
      // assertions on parameters
      // ...
      true
    }
  }).returns(mockRequestHolder)

  val stubResponse = stub[WSResponse]
  val jsonBody = "{}"
  (stubResponse.json _).when().returns(Json.parse(jsonBody))
  (mockRequestHolder.get _).expects().returns(Future(stubResponse))
}

当我尝试模拟WSRequestHolder的任何其他方法时，模拟会起作用，但不能使用Get方法。

这是ScalaMock bug还是我做错了什么？

我不知道您是否已经解决了这个问题，但我最近尝试做了类似的事情，我使用以下代码获得了它：

val wsClientMock = mock[WSClient]
val wsRequestMock = mock[WSRequest]
val wsResponseMock = mock[WSResponse]
(wsRequestMock.withAuth _).expects(username, password, WSAuthScheme.BASIC).returning(wsRequestMock)
(wsRequestMock.get _).expects().returning(Future[WSResponse](wsResponseMock))
(wsClientMock.url _).expects(bootstrapUrl).returning(wsRequestMock)
(wsResponseMock.status _).expects().returning(200)

“有点”，因为我也需要模仿响应，否则我会得到如下结果

ERROR[default-akka.actor.default-dispatcher-4] OneForOneStrategy - Unexpected call: json()

因为调用WSClient的代码正在调用WSResponse的method.json。
