I want to test a (quite large) variety of user-defined types using Boost.Test. As a very contrived example, suppose I wanted to check numeric_limits digits for integer types I'd like to avoid a tediously long list like this BOOST_CHECK_EQUAL(std::numeric_limits<char>::digits, 8); BOOST_CHECK_EQUAL(std::numeric_limits<char>::digits, 16); BOOST_CHECK_EQUAL(std::numeric_limits<char>::digits, 32); ... and follow the example of BOOST_AUTO_TEST_CASE_TEMPLATE but allow a test value to be passed too, something like this: typedef boost::mpl::list<char, int, long> test_types; and a list of test values, perhaps like this typedef list_c<int, 8, 32, 64> test_values; (However it would be *far* more useful to be able to test strings and floats and User-defined types too). BOOST_AUTO_TEST_CASE_TEMPLATE_????(digits_test, T, test_types, test_values) { BOOST_CHECK_EQUAL(std::numeric_limits<T>::digits, test_values); } Has any Macro Guru produced a BOOST_AUTO_TEST_CASE_TEMPLATE_? that includes a list of test values? Or other suggestions. Thanks Paul --- Paul A. Bristow Prizet Farmhouse Kendal UK LA8 8AB +44 (0) 1539 561830
