Depends on what you mean by policy based designs.

Well, although the problem certainly isn't trivial, I think that the
problem isn't nearly as hard as it may seem. (Of course, it is quite
difficult to write tests for user-defined policies in advance. :)

The basic idea is explained in C&E (I don't have it at home so I
can't give page numbers for reference). Basically you just write a
suitable test generator (template).

However, I'm not so sure that all combinations need to be tested. You
should concentrate testing on what might brake. I'd probably start
with O(1) test cases per policy. Then I'd analyze where policy
interaction needs to be considered.
