// Revision History
// 03 Apr 08 Added convertible_to_bool (Daniel Frey)
// 01 Oct 01 Added tests for "left" operators
// and new grouped operators. (Helmut Zeisel)
// 20 May 01 Output progress messages. Added tests for new operator
// templates. Updated random number generator. Changed tests to
// use Boost Test Tools library. (Daryle Walker)
// 04 Jun 00 Added regression test for a bug I found (David Abrahams)
// 17 Jun 00 Fix for broken compilers (Aleksey Gurtovoy)
// ?? ??? 00 Major update to randomly test all one- and two- argument forms by
// wrapping integral types and comparing the results of operations
// to the results for the raw types (David Abrahams)
// 12 Dec 99 Minor update, output confirmation message.
// 15 Nov 99 Initial version
#include <boost/config.hpp> // for BOOST_MSVC
#include <boost/operators.hpp> // for the tested items
#include <boost/utility/detail/minstd_rand.hpp> // for boost::detail::minstd_rand
#include <boost/core/lightweight_test.hpp>
