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.
