 It is possible to test several types using BOOST_AUTO_TEST_CASE_TEMPLATE

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

 BOOST_AUTO_TEST_CASE_TEMPLATE( my_test, T, test_types )
 {
   BOOST_TEST( sizeof(T) == (unsigned)4 );
 }
 }}}

 But if I don't want to introduce a typedef not used elsewhere, as every
 individual test would have separate type list:

 {{{
 BOOST_AUTO_TEST_CASE_TEMPLATE(
    my_test,
    T,
    boost::mpl::list<
      int,
      long,
      unsigned char
    > )
 {
   BOOST_TEST( sizeof(T) == (unsigned)4 );
 }
 }}}
 The code above doesn't compile though due to comma in macro. It can be
 worked around, but workarounds seems to be worse than having extra
 typedef.

 I propose using variadic macro for types parameter and make the example
 above compiling.
