I would recommend against using one component of the library
(static_assert) to test another.

The approach taken by existing tests is to verify types and
signatures by using them in ways that would make the tests
ill-formed if they didn't match the requirements, causing
a compiler error. You can see examples of this approach in
the 23.vector.cons.cpp test that was just mentioned.
