Boost C++ Libraries

...one of the most highly regarded and expertly designed C++ library projects in the world. — Herb Sutter and Andrei Alexandrescu, C++ Coding Standards

This is the documentation for an old version of Boost. Click here to view this page for the latest version.

`BOOST_<level>_NE`

BOOST_WARN_NE(left, right);
BOOST_CHECK_NE(left, right);
BOOST_REQUIRE_NE(left, right);

Check performed by these tools is the same as the one performed by BOOST_<level>( left != right ). The difference is that the matched values are reported as well.

Example: BOOST_<level>_NE usage

Code
#define BOOST_TEST_MODULE example #include <boost/test/included/unit_test.hpp> BOOST_AUTO_TEST_CASE( test ) { int i = 3; int j = 3; BOOST_CHECK_NE( i, j ); }

Output
>example Running 1 test case... test.cpp(10): error in "test": check i != j failed [3 == 3] *** 1 failures is detected in test suite "example"
