[boost] [test] Test cases parametrized by both type and value?

Hi, Can anyone tell me if Boost.Test can solve the problem that I describe below. I have a function template inspect: ``` template <typename T> bool inspect(T const& v); ``` I want to test if it returns `true` for the following values: 1 (type int) 10 (type int) 1.0 (type double) "Y" (type const char *) Basically, different values of different types, but sometimes different values have the same type. I would like to write one test or "test template" with the following contents: ``` BOOST_TEST((inspect(v))); ``` Where `v` is name of the currently tested value. (But `v`s will have different types). I can emulate this behavior using template test cases and artificial types: ``` struct int_1 { static int value() { return 1; } }; struct int_10 { static int value() { return 10; } }; struct double_1 { static double value() { return 1.0; } }; struct cstr_Y { static const char * value() { return "Y"; } }; typedef boost::mpl::list test_types; BOOST_AUTO_TEST_CASE_TEMPLATE( my_test, T, test_types ) { BOOST_TEST(inspect(T::value())); } ``` (See working example in WandBox: https://wandbox.org/permlink/KcJqT8KvL3zIqAxL) But maybe there exists a direct solution in Boost.Test? Where I would just pass a list of values: `{1, 10, 1.0, "Y"}` It is easy to deduce types from values: ``` template mpl::liss Values(T... values); using test_types = decltype(Values(1, 10, 1.0, "Y")); ``` Does something like this exist, or ois it a reasonable extension?
