BOOST_level_GT(lhs, rhs) asserts that lhs is greater than rhs. The comparison is made by applying operator> to both arguments. The diagnostic message is constructed from applying operator<< to the two arguments.

Important

If you get a strange compile error when using BOOST_level_GT, check that the appropriate operator> and operator<< are defined for the arguments. If you define these operators in your test code, keep in mind argument-dependent lookup of types based on enclosing namespaces and the namespaces opened by test suites. The need to define operator<< can be eliminated by using BOOST_TEST_DONT_PRINT_LOG_VALUE.

Example

BOOST_AUTO_TEST_CASE(example_gt)
{
    // integral types
    unsigned const u = 1u;
    int const i = -10;
    char const A = 'A';
    // standard library types providing operator> and operator==
    std::string const s = "scooby";

    BOOST_REQUIRE_GT(2u, u);
    BOOST_REQUIRE_GT(-9, i);
    BOOST_REQUIRE_GT('B', A);
    BOOST_REQUIRE_GT("scoobz", s);
}
