I'll fix that and resubmit. Â Is there documentation on what do_test
should return? Â I looked at test-skeleton.c but there was nothing in
there about what do_test/TEST_FUNCTION should return for different
results (PASS/FAIL/UNSUPPORTED). Â I didn't see anything in the Wiki
about return values from do_test either.
