If you're going to use multiple files, it's better not to
include everything in a single translation unit.
As long as BOOST_TEST_MAIN and
BOOST_TEST_MODULE are only defined
in one translation unit you can link multiple
translation units together.  BOOST_TEST_DYN_LINK
needs to be defined in every translation unit.

If you mean auto-import, that's normal on cygwin.
