Yeah, most assertion frameworks have some way to optionally provide a
message.  Since Boost.Test's assertions are done with macros, there
isn't a way to provide an overloaded version that supplies a
contextual message.  I'm afraid the best you can do is use
BOOST_REQUIRE_MESSAGE() or provide your own assertion macros on top of
it.
