Say you have a arbitrary class under test, which is dependent on a class DataProcessor which has a method with the following signature:

 String processData(String data, MultivaluedMap  params, Token token)

you might want to stub it with Mockito 1.9.5 in the following way to match the generic typed class:

when(dataProcessor.processData(anyString(), any(MultivaluedMap.class), any(Token.class))).thenReturn(processedData);

However running this, gives the following error:

Invalid use of argument matchers!
3 matchers expected, 4 recorded:
[ ....]

This exception may occur if matchers are combined with raw values:
    someMethod(anyObject(), "raw String");
When using matchers, all arguments have to be provided by matchers.
For example:
    someMethod(anyObject(), eq("String by matcher"));

This is caused by the generic typed MulitvaluedMap. Solution:

 MultivaluedMap  map = Mockito.any();
 when(dataHandlerMock.getResult(anyString(), map, any(TokenDataBean.class))).thenReturn(jsonString);

Run the test and it will pass (these lines at least :-)! Original Post
