[Boost-users] Re: BOOST_CHECK_EQUAL and operator<<

However, it does not work with typedefed types. Here is a new example :

//********************* #include <boost/test/unit_test.hpp> using boost::unit_test::test_suite;

namespace testns {

typedef std::pair<int, std::string> Test;

std::ostream& operator<<(std::ostream& o, Test const& t) { return o<<t.first<<t.second; }

Try writing: namespace std { std::ostream& operator<<(std::ostream& o, std::pair<int, std::string> const& t) { return o<<t.first<<t.second; } } I think namespace std is the only place that will be searched for operator<< (except for boost:: and for boost::test_tools and boost::test_tools::tt_detail). - Volodya
