#11854: Add fixture support in BOOST_DATA_TEST_CASE
------------------------------+---------------------
 Reporter:  mikhail@…         |      Owner:  rogeeff
     Type:  Feature Requests  |     Status:  new
Milestone:  To Be Determined  |  Component:  test
  Version:  Boost 1.59.0      |   Severity:  Problem
 Keywords:                    |
------------------------------+---------------------
 Now BOOST_DATA_TEST_CASE doesn't support test fixture at all. There is the
 ability to support this:
 {{{
 #define BOOST_FIXTURE_DATA_TEST_CASE_IMPL( arity, test_name, F, dataset,
 params )  \
 struct test_name : public F {
 \
     template<BOOST_PP_ENUM_PARAMS(arity, typename Arg)>
 \
     static void test_method( BOOST_DATA_TEST_CASE_PARAMS( params ) )
 \
     {
 \
         BOOST_TEST_CHECKPOINT('"' << #test_name << "\" fixture entry.");
 \
         test_name t;
 \
         BOOST_TEST_CHECKPOINT('"' << #test_name << "\" entry.");
 \
         BOOST_TEST_CONTEXT( ""
 \
             BOOST_PP_SEQ_FOR_EACH(BOOST_DATA_TEST_CONTEXT, _, params))
 \
         t._impl(BOOST_PP_SEQ_ENUM(params));
 \
         BOOST_TEST_CHECKPOINT('"' << #test_name << "\" exit.");
 \
     }
 \
 private:
 \
     template<BOOST_PP_ENUM_PARAMS(arity, typename Arg)>
 \
     void _impl(BOOST_DATA_TEST_CASE_PARAMS( params ));
 \
 };
 \

 BOOST_AUTO_TU_REGISTRAR( test_name )(
 \
     boost::unit_test::data::ds_detail::make_test_case_gen<test_name>(
 \
           BOOST_STRINGIZE( test_name ),
 \
           __FILE__, __LINE__,
 \
           boost::unit_test::data::make(dataset) ),
 \
     boost::unit_test::decorator::collector::instance() );
 \
 \
 template<BOOST_PP_ENUM_PARAMS(arity, typename Arg)>
 \
 void test_name::_impl( BOOST_DATA_TEST_CASE_PARAMS( params ) )
 \
