Scala: org.mockito.internal.invocation.Invocation.isToString和Specs2 : java.lang.NoSuchMethodError：

Question

我在用Specs2和Mockito运行Scala单元测试时遇到了问题。

val response = mock[Response]

"MyResource" should {
    "handle NOT_FOUND from another WS" in {
      response.status returns NOT_FOUND // Exception thrown here
      anotherWS.getDetails("101010", "101") returns Future.successful(response)
      .....
    }

异常：

org.mockito.internal.invocation.Invocation.isToString(Lorg/mockito/invocation/InvocationOnMock;)Z
org.specs2.execute.Error$ThrowableException: NoSuchMethodError: org.mockito.internal.invocation.Invocation.isToString(Lorg/mockito/invocation/InvocationOnMock;)Z

Answer 1

更新到mockito 1.9.5 (使用1.8.5)修复了这个问题

Answer 2

Mockito不支持模拟变量。status是response对象上的变量吗？如果是这样的话，一个解决方案是定义一个getStatus()方法，然后模拟该方法。
