So TBH I don't think the failure rate for these tests are really at a point
necessitating a skip:
(also just a cool side-note, you can see the very obvious performance regression
caused by the keystonemiddleware release and when we excluded that version in
Well, test_dualnet_dhcp6_stateless_from_os is kinda there with a ~10% failure
rate, but the other 2 really aren't. I normally would be -1 on the skip patch
because of that. We try to save the skips for cases where the bugs are really
severe and preventing productivity at a large scale.
But, in this case these ipv6 tests are kinda of out of place in tempest. Having
all the permutations of possible ip allocation configurations always seemed a
bit too heavy handed. These tests are also consistently in the top 10 slowest
for a run. We really should have trimmed down this set a while ago so we're only
have a single case in tempest. Neutron should own the other possible
configurations as an in-tree test.
Brian Haley has a patch up from Dec. that was trying to clean it up:
We probably should revisit that soon, since quite clearly no one is looking at
these right now.
