17 * General tests for wcsncasecmp(). Test to make sure that the following are
18 * true:
19 *
20 * o Two identical strings are equal
21 * o Two strings with the same contents are equal
22 * o Case insensitive in ASCII works
23 * o Basic cases where strings aren't equal
24 * o An ASCII string that would compare greater due to case is properly less
25 * o Comparing with zero characters succeeds even if different strings
26 * o Characters in a locale / language that don't have a notion of case are
27 * consistent
