i trying pass wildcard mockito any() method. method

when(gatewayconfigselector.selectgatewayinfoconfig( any(operation.class));             .thenreturn(...something...); 

example:

@test public void test() {     tester mock = mockito.mock(tester.class);     mockito.when(mock.selectgatewayinfoconfig(mockito.any(operation.class))).thenreturn("blah");      system.out.println(mock.selectgatewayinfoconfig(null)); }   class operation<t> {  }  class tester {      public string selectgatewayinfoconfig(operation<?> o) {         return "hi";     } }
