Mockito Java 8 argument matcher any(Class <T>)

I need to pass Class to argument matcher. Here is what I am doing and my match should return object apiResponse which is not null since I am creating it and passing it along. But, it does not seem to be injecting it; I receive it as null.

I have tried it also with ArgumentMatchers.eq(ApiResponse.class),Mockito.eq(ApiResponse.class), ArgumentMatchers.any(ApiResponse.class) and Mockito.any(ApiResponse.class).

With ArgumentMatchers.any(ApiResponse.class) and Mockito.any(ApiResponse.class), the code won't even compile, and with ArgumentMatchers.eq(ApiResponse.class),Mockito.eq(ApiResponse.class), I receive null on the other side. Please suggest!

      ApiResponse apiResponse = new ApiResponse();
      apiResponse.setErrcode("0");
      apiResponse.setNum_fields_changed("1");
      Mockito.when(xmlResponseMapper.parseXMLToObject(any(String.class),ArgumentMatchers.eq(ApiResponse.class))).thenReturn((apiResponse));

Here is where I use this matcher in my class

  apiResponse = xmlResponseMapper.parseXMLToObject(response.getBody(), ApiResponse.class);

Did I do something wrong? I am using Java 8.

It is solved. The issue was actually not with ArgumentMatchers.eq(ApiResponse.class) but with the String, the first parameter being passed in the matcher

  Mockito.when(xmlResponseMapper.parseXMLToObject(any(String.class),ArgumentMatchers.eq(ApiResponse.class))).thenReturn((apiResponse));

I was passing null as the first parameter. Once I passed a dummy string, it all went fine and I received apiResponse on the other side.

With ArgumentMatchers.any(ApiResponse.class) and Mockito.any(ApiResponse.class), the code won't even compile

As your method expects a class type, those matchers return an object of specified type.

You need to specify the matcher with the exact class that that you intend to pass:

Mockito.when(xmlResponseMapper.parseXMLToObject(any(String.class),
 ArgumentMatchers.eq(QuickBaseApiResponse.class))).thenReturn((apiResponse));

If you pass the ApiResponse to eq(), then there wont be a match as ApiResponse.class and QuickBaseApiResponse.class are different instances and the method will always resolve to false.

Also the apiResponse needs to be of type QuickBaseApiResponse.
