I've implemented a test for boost.container and I've found expanding
BOOST_TEST_THROWS to nothing if BOOST_NO_EXCEPTIONS is defined is quite
useful to maintain my test case clean. I only need to know that the
expression won't be executed so if I call:
I can't write my test supposing "reserve" will be called. I think it's a
good idea to avoid forcing users wrapping each BOOST_TEST_THROWS with
#ifndef BOOST_NO_EXCEPTIONS/#endif. Patch attached with implementation
and more comments. Ok to commit?
