The libhugetlbfs test suite has various tests for which a failure (under
certain circumstances) is expected and not indicative of an error. It would be
desirable to specially annotate these cases to eliminate the need for the
tester to know which failures are known and which could be bugs.
This patch creates some test harness infrastructure that can be used to achieve
this goal. How does it work? If a test case needs expected failure
validation, a shell script (named <testcase>.sh) is placed in the tests/
directory. The test invocation in run_tests.sh is changed to execute the shell
script instead of the c program directly. The shell script must perform any
required discovery, execute the real test case, and interpret the result.
Comments?
