I have had nothing but troubles with boost test 1.34.1 after switched from 1.33. First I had trouble with the main from shared object issue, and now my code that worked before is not executing a test added to the framework.

#include <iostream> #define BOOST_TEST_DYN_LINK #define BOOST_TEST_MAIN #define BOOST_TEST_MODULE File Test #include #include

template <typename Functor> struct my_test { void execute(int value) { //Never prints this message //Doesn't have to be a print, nothing gets here std::cerr << "Hi all" << std::endl << std::flush; } };

BOOST_AUTO_TEST_CASE( test123 ) { boost::shared_ptr tester(new my_test<int>);

boost::unit_test::framework::master_test_suite().add(BOOST_TEST_CASE(boost::bind(&my_test<int>::execute, tester, 5))); }

This is incorrect way to register test units.

this worked when it was not using boost::bind but just the address of a normal function. This is just an simple version that illustrated the problem. I am compiling as such g++ test.cpp -o test -L/usr/local/lib -lboost_unit_test_framework-gcc41-mt

I am not sure how it worked before, but the correct way to implement this is to use init function

#include <iostream> #define BOOST_TEST_DYN_LINK #include #include

template <typename Functor> struct my_test { void execute(int value) { //Never prints this message //Doesn't have to be a print, nothing gets here std::cerr << "Hi all" << std::endl << std::flush; } };

bool init_function() { boost::shared_ptr tester(new my_test<int>);

boost::unit_test::framework::master_test_suite().add( BOOST_TEST_CASE(boost::bind(&my_test<int>::execute, tester, 5)));

return true; }

int main( int argc, char* argv[] ) { return ::boost::unit_test::unit_test_main( &init_function, argc, argv ); }

P.S. Alternatively, if you are not that interrested in either template or runtime parameter, you can use one of the other automated tools. For example:

#include <iostream> #define BOOST_TEST_DYN_LINK #define BOOST_TEST_MODULE Your test #include

typedef boost::mpl::list test_types;

BOOST_AUTO_TEST_CASE_TEMPLATE( test_case1, T, test_types ) { //Never prints this message //Doesn't have to be a print, nothing gets here std::cerr << "Hi all" << std::endl << std::flush; }

Thanks, worked like a charm. I do believe though that there should be better documentation for this great library. Chris Miceli
