Is it possible to use BOOST_PARAM_TEST_CASE with automatic registration on boost::test?

Question

Is it possible to mix up the BOOST_AUTO_TEST_CASE and BOOST_AUTO_TEST_CASE_TEMPLATE macros with the BOOST_PARAM_TEST_CASE in any way? I\'m

Answer 1

I wrote my own support for this since there really didn't seem to be any good support. This requires the C++11 decltype feature and the ::std::remove_const and ::std::remove_reference library methods to work.

The macro definitions are a modified versions of the BOOST_FIXTURE_TEST_CASE and BOOST_AUTO_TEST_CASE macros.

You use this by declaring your function thus:

BOOST_AUTO_PARAM_TEST_CASE(name, begin, end)
{
    BOOST_CHECK_LT(param, 5);  // The function will have an argument named 'param'.
}

Here is the header that defines the BOOST_AUTO_PARAM_TEST_CASE macro:

#include 
#include 
#include 

#define BOOST_FIXTURE_PARAM_TEST_CASE( test_name, F, mbegin, mend )     \
struct test_name : public F {                                           \
   typedef ::std::remove_const< ::std::remove_reference< decltype(*(mbegin)) >::type>::type param_t; \
   void test_method(const param_t &);                                   \
};                                                                      \
                                                                        \
void BOOST_AUTO_TC_INVOKER( test_name )(const test_name::param_t ¶m) \
{                                                                       \
    test_name t;                                                        \
    t.test_method(param);                                               \
}                                                                       \
                                                                        \
BOOST_AUTO_TU_REGISTRAR( test_name )(                                   \
    boost::unit_test::make_test_case(                                   \
       &BOOST_AUTO_TC_INVOKER( test_name ), #test_name,                 \
       (mbegin), (mend)));                                              \
                                                                        \
void test_name::test_method(const param_t ¶m)                       \
