Hi,

I'm using Google Mock. It's quite powerful and in my opinion very
clear. But you have to write some glue code to make it work with Boost
Test. Something like this:

class BoostTestAdapter: public EmptyTestEventListener {

virtual void OnTestPartResult(const TestPartResult& testPartResult);
{
    if (testPartResult.failed()) {
        std::stringstream s;
        if (testPartResult.file_name())
        {
            s << std::endl
                << testPartResult.file_name()
                <<"(" << testPartResult.line_number() << "): "
                << testPartResult.summary();
        }
        else
        {
            s << std::endl
                << "unknown file: "
                << testPartResult.summary();
        }
        BOOST_ERROR(s.str());
    }
}

};

struct GoogleMockFixture {

GoogleMockFixture::GoogleMockFixture()
{
    InitGoogleMock(&boost::unit_test::framework::master_test_suite().argc,
        boost::unit_test::framework::master_test_suite().argv);
    TestEventListeners &listeners = UnitTest::GetInstance()->listeners();
    delete listeners.Release(listeners.default_result_printer());
    listeners.Append(new BoostTestAdapter);
}

~GoogleMockFixture() {}

};

BOOST_GLOBAL_FIXTURE(GoogleMockFixture)

The error reporting is not perfect yet, but usually you get the source
file and line of the error directly in the error message.

Hope that helps!
