I committed something similar for the BGL test suite (test_graph.cpp, I
think in trunk). It's not nearly as formal and primarily just exercises the
Graph concept interfaces. Mostly it's just a framework for sanity testing a
graph adaptor or data structure. Also virtually no documentation.
One of the things that I found was that generically testing data structures
requires a fairly complete set of type traits and metafunctions that query
types based on their concepts. I'm using these to extensively tag dispatch
some of the test methods.
It seems like a good approach, but it's not easy to write.
