Is it possible to use Boost.Test macros with std::wstring directly like this: BOOST_TEST_MESSAGE(L"test log"); ?

Boost.Test internally uses std::ostream. So if you want above to work you'll need to supply appropriate output method.

Proper wide string support is not implemented yet.

Thanks for the answer, Gennadiy. While I could wrap it with another layer, it'll be great if it's a built-in feature, so that I won't copy some additional code around while using boost.test, esp. that these days I started every little project with these 2 lines: #define BOOST_TEST_MODULE my #include Is this decision out of convenience or any implementation obstacle. Specifically, what would be the problems if std::basic_ostream<Ch> is used instead?
