Here is my example:

#include "stdafx.h"
#define BOOST_TEST_MODULE example
#include <boost/test/included/unit_test.hpp>

std::list<int>* user_defined_func( ) {
        std::cout << "BEGIN: user_defined_func" << std::endl;
        std::list<int>* l = new std::list<int>;

        l->push_back(8);
        l->push_back(0);

        std::cout << "END: user_defined_func" << std::endl;

        return l;
}

bool validate_list(std::list<int> &L1)
{

   std::cout << "BEGIN: validate_list" << std::endl;

   std::list<int>::iterator it1 = L1.begin();

   for(; it1 != L1.end(); ++it1)
   {
      if(*it1<= 1){

             std::cout << "Validation failed because an item in the list was
less than or equal to 1." << std::endl;
                 std::cout << "END: validate_list" << std::endl;
         return false;
       }
   }

   std::cout << "Test passed because all of the items in the list were
greater than or equal to 1" << std::endl;
   std::cout << "END: validate_list" << std::endl;
  return true;
}

BOOST_AUTO_TEST_SUITE( test )
BOOST_AUTO_TEST_CASE( test )
{
   std::list<int>* list1 = user_defined_func();
   BOOST_CHECK_PREDICATE( validate_list, (list1) );
}
BOOST_AUTO_TEST_SUITE_END()

Thank you,
