     Lots of things are the hard part of testing.  :(

     Some practitioners who have given the matter much more thought
than I ever will are scrupulous about distinguishing between "unit
tests" and "integration tests" and "system tests" (Aside: when did
"acceptance tests" go out of fashion?), but to me the demarcation
lines seem not perfectly sharp.  A test for your A/B/D example might
be viewed as an integration test of the A/B/D methods, or as a unit
test of the component that owns all three (does it make the advertised
state transitions in the expected way?).  Deeper thinkers than I may
have a useful way to classify such things; for myself, I just try to
figure out Some Kind Of Test and let the nomenclature slide.
