BOOST_TEST(statement); BOOST_TEST_<level>(statement); // replacement failure message, requires variadic macros BOOST_TEST(statement, "failure message"); // Floating point comparison, requires variadic macros, auto and decltype BOOST_TEST(statement, floating_point_comparison_manipulation); // bitwise comparison, requires variadic macros, auto and decltype BOOST_TEST(statement, boost::test_tools::bitwise() ); // element-wise comparison, for containers BOOST_TEST(statement, boost::test_tools::per_element() ); // lexicographic comparison, for containers BOOST_TEST(statement, boost::test_tools::lexicographic() );
The full documentation of this macro is located here.
The macro is available in three variants, corresponding to different assertion severity levels:
BOOST_TEST // or BOOST_TEST_CHECK BOOST_TEST_REQUIRE BOOST_TEST_WARN
"failure message"
              is a C-string printed in case of failure in place of the default message.
              See this section
              for more details.
            floating_point_comparison_manipulation
              is one of the floating point comparison manipulators. See this
              section for more details.
            boost::test_tools::bitwise
              is a manipulator indicating that the comparison should be performed
              bitwise. See this
              section for more details
            boost::test_tools::per_element
              is a manipulator indicating that the comparison should be performed
              on each element, in sequence, rather than on containers. See this section for more details
            boost::test_tools::lexicographic
              is a manipulator indicating that the comparison should be performed
              with the lexicographic order. See this
              section for more details
            There are some restrictions on the statements that are supported by this tool. Those are explained in details in this section.
