[boost] Boost.Test with templated test cases... or is it bind? (was: How to make Boost.Test work with function objects?)

   Bonjour

      OK, I tried to use the following advice:

      I am stumbling on another problem, though.

Given

   boost::unit_test_framework::test_suite *  test = BOOST_TEST_SUITE("");

if I have the following normal function

   void  fn(int)
   {
   }

then I can do the following

   test->add(BOOST_TEST_CASE(::boost::bind(&fn, 1)));

but if I have a templated functions instead

   template<typename T>
   void  ft(int)
   {
   }

then the following invocation will not compile

   test->add(BOOST_TEST_CASE(::boost::bind(&ft<int>, 1)));

the error message being

   Error   : function call 'bind(void, int)' does not match
