Hi The code below reports 2 failed assertions of 3. If you comment out one of the BOOST_CHECK macros, it reports 1 failed assertion of 1. Is the extra assertion expected behaviour? Thanks Jorge #include <boost/test/unit_test.hpp> using boost::unit_test::test_suite; void free_test_function() { // reports 'error in "free_test_function": test 2 == 1 failed' BOOST_CHECK(5 == 1); // non-critical test => continue after failure BOOST_CHECK(6 == 1); // non-critical test => continue after failure } test_suite* init_unit_test_suite( int, char* [] ) { test_suite* test= BOOST_TEST_SUITE( "Unit test example 1" ); // this example will pass cause we know ahead of time number of expected failures test->add( BOOST_TEST_CASE( &free_test_function ), 2 /* expected one error */ ); return test; }
