Scala Spec2 Mockito:具有复杂类型的参数匹配器

Question

我正在尝试用Mockito为web服务编写一个模拟。mock应该使用play WS库模拟POST请求。

/**
 * Mock for the  Web Service
 */
case class WSMock() extends Mockito {
  val wsRequestHolder: play.api.libs.ws.WS.WSRequestHolder = mock[play.api.libs.ws.WS.WSRequestHolder]

  val wsResponse: play.api.libs.ws.Response = mock[play.api.libs.ws.Response]
  wsResponse.status returns 200
  wsResponse.body returns "BODY RESP FROM WS"

  val futureResponse = scala.concurrent.Future { wsResponse }

  wsRequestHolder.post(any[Map[String,Seq[String]]]) returns futureResponse
}

在运行测试时，我得到以下错误：

[error]     InvalidUseOfMatchersException: 
[error] Invalid use of argument matchers!
[error] 3 matchers expected, 1 recorded:
[error] -> at org.specs2.mock.mockito.MockitoMatchers$class.any(MockitoMatchers.scala:24)
[error] 
[error] This exception may occur if matchers are combined with raw values:
[error]     //incorrect:
[error]     someMethod(anyObject(), "raw String");
[error] When using matchers, all arguments have to be provided by matchers.
[error] For example:
[error]     //correct:
[error]     someMethod(anyObject(), eq("String by matcher"));
[error] 
[error] For more info see javadoc for Matchers class.

在我看来，它就像是...使用复杂类型(带有嵌套类型参数)的表达式无法正确解析为匹配器。然而，我看不出原始类型在哪里起作用。为参数Map[String,Seq[String]]指定这样的匹配器的正确方法是什么

非常感谢!

Answer 1

wsRequestHolder.post(any[Map[String,Seq[String]]]) returns futureResponse

注意，post实际上有两个额外的隐式参数：

def post [T] (body: T)(implicit wrt: Writeable[T], ct: ContentTypeOf[T]):
    Promise[Response]

在this spec2-users thread中，...which可能需要显式匹配。

Answer 2

似乎wsRequestHolder.post方法需要三个参数，所以Mockito希望你发送三个匹配器(例如any[])，但你只为其中一个提供了匹配器。
