Customizing the module's entry point

In this variant, in one of the source files, you now have to define your custom entry point, and invoke the default test runner unit_test_main manually with the default initialization function init_unit_test as argument. You need to define BOOST_TEST_NO_MAIN (its value is irrelevant) in the main file:

In exactly one file	In all other files
#define BOOST_TEST_MODULE test module name #define BOOST_TEST_DYN_LINK #define BOOST_TEST_NO_MAIN #include <boost/test/unit_test.hpp> // entry point: int main(int argc, char* argv[], char* envp[]) { return boost::unit_test::unit_test_main( &init_unit_test, argc, argv ); }	#define BOOST_TEST_DYN_LINK #include <boost/test/unit_test.hpp> // // test cases // // // test cases //
