Test case template with automated registration

To create a test case template registered in place of implementation, employ the macro BOOST_AUTO_TEST_CASE_TEMPLATE. This facility is also called auto test case template.

BOOST_AUTO_TEST_CASE_TEMPLATE(test_case_name, formal_type_parameter_name, collection_of_types)

The macro BOOST_AUTO_TEST_CASE_TEMPLATE requires three arguments:

The test case template name	unique test cases template identifier
The name of a formal template parameter	name of the type the test case template is instantiated with
The collection of types to instantiate test case template with	arbitrary MPL sequence

Example 14. Test case template with automated registration

#define BOOST_TEST_MODULE example
#include <boost/test/included/unit_test.hpp>
#include <boost/test/test_case_template.hpp>
#include <boost/mpl/list.hpp>

//____________________________________________________________________________//

typedef boost::mpl::list<int,long,unsigned char> test_types;

BOOST_AUTO_TEST_CASE_TEMPLATE( my_test, T, test_types )
{
    BOOST_CHECK_EQUAL( sizeof(T), (unsigned)4 )
}

//____________________________________________________________________________//
