[DTrace-devel] Test that PASSes but should not

[Kris Van Hees]

This is not a good thing:

test/unittest/ip/tst.ipv4localicmp.sh: Running timeout --signal=TERM 41 test/unittest/ip/tst.ipv4localicmp.sh /home/kvanhees/dtrace-bpf-user/build/dtrace
PASS.

That failure definitely should cause the test to fail.
