I think that that's the main point. As long as policies are orthogonal, they
can be tested in isolation. For example, if CheckingPolicy doesn't interact
with any other policy, a suite can test all CheckingPolicy implementations
using some arbitrary choices for the other policies.

Otherwise, I was thinking of a testing strategy similar to Jeremy's - tests
are generated by templates, and testing specific cases/behaviors are modeled
with specialization of the test cases.
