It sounds, from your description so far, that you have identified a
design flaw in D1 and D2.

The common functionality should be moved to a common code point (maybe a
base class of D1 and D2; maybe a function without need of a class). Then
you'll have only one occurrence of that functionality to test, which is
good design as well as easier test code :-)
