java - Mockito- calling real method -

I have a class that has 2 ways, I want to duplicate the class and then mimic the first method , But not the second.

Example

  class C {void m1 () {...} boolean m2 () {... return flag;}}   
 unit test code:  
  c cock = Mockito.mock (C.class); . (Mockito.doNothing) when (cMock) .m1 (); Mockito.when (cMock.m2 ()) thenCallRealMethod () .; The strange thing is that M2 is not being called.  
 Do I miss anything here?   
 
 
 This is also where  Mockito.spy  can be used is. This allows you to partial mocks on real objects.  
  c cock = Mockito.spy (new C ()); . (Mockito.doNothing) when (cMock) .m1 ();
