xtd::tunit::collection_assert::all_items_are_instances_of_(std::basic_ostream<char>*, a, "User message..."); // test error.
xtd::tunit::collection_assume::all_items_are_instances_of_(std::ios_base*, a); // test ok.
xtd::tunit::collection_assume::all_items_are_instances_of_(std::basic_ostream<char>*, a, "User message..."); // test error.
