Boost C++ Libraries

...one of the most highly regarded and expertly designed C++ library projects in the world. — Herb Sutter and Andrei Alexandrescu, C++ Coding Standards

`BOOST_TEST_MAIN`

When defined, this macro creates a stub for the test module initialization (the main entry part). This macro also expands properly into a main function in case the shared library variant of the Unit Test Framework is used.

	Caution
	This macro should be defined before any inclusion directive to Unit Test Framework headers be defined exactly for one compilation unit of your test module

	Tip
	The macro `BOOST_TEST_MODULE` should be preferred
