I am not sure I understand you. But if you mean to test all models against
all contracts you can use 2 mpl::vectors with 2 nested mpl::for_each loops.
http://www.boost.org/doc/libs/1_35_0/libs/mpl/doc/refmanual/for-each.html

The first mpl::for_each picks from the model vector a type and passes it to
a test suite, the other mpl::for_each iterates through the contract vector
and calls a corresponding test function for the model and contract.

And one more thing:
mpl::vector is by default limited by 20 entries. Please read here how to
increase this limit
