BOOST_TEST comparing two char*/wchar_t*

[mikhail.strelnikov@…]

BOOST_TEST should compare pointers, not strings.

Consider:

char s[] = {65, 0, 65, 0};
char *c1 = &s[0], *c2 = &s[2];
if (c1 != c2)
{
    BOOST_TEST(c1 != c2);
}

Error looks like this:

check c1 != c2 has failed [A == A]

With wchar_t:

check c1 != c2 has failed [0x7ffc3b6d9bb0 == 0x7ffc3b6d9bb8]

This is well explained in the documentation: http://www.boost.org/doc/libs/1_65_1/libs/test/doc/html/boost_test/testing_tools/extended_comparison/strings.html

If you want to compare pointers, maybe you can just use

BOOST_TEST((void*)c1 != (void*)c2);

instead?

Note that BOOST_TEST does not support wchar_t comparisons well, as mentioned in other bug reports. Closing this ticket.
