Description Bernard Cafarelli 2017-06-09 08:00:19 UTC

Description of problem:

some DHCPv6 API tests fail in CI runs, like:
tempest.api.network.test_dhcp_ipv6.NetworksTestDHCPv6.test_dhcp_stateful
tempest.api.network.test_dhcp_ipv6.NetworksTestDHCPv6.test_dhcpv6_64_subnets

This upstream change fixes this problem (removing the expectation that assigned IP will be the first or second in the pool):
https://review.openstack.org/#/c/185616/

Version-Release number of selected component (if applicable):
openstack-tempest-kilo-20151020.1.el7ost

How reproducible: 100%


Steps to Reproduce:
1. Deploy RHOSP 7
2. Run Tempest API DHCP IPv6 tests

Actual results:
Traceback (most recent call last):
  File "/home/stack/tempest-dir/tempest/api/network/test_dhcp_ipv6.py", line 224, in test_dhcpv6_two_subnets
    str(dhcp_ip)))
  File "/usr/lib/python2.7/site-packages/testtools/testcase.py", line 354, in assertIn
    self.assertThat(haystack, Contains(needle), message)
  File "/usr/lib/python2.7/site-packages/testtools/testcase.py", line 433, in assertThat
    raise mismatch_error
MismatchError: u'2003:0:0:1::4' not in [u'2003:0:0:1::2', '2003:0:0:1::3']: Real IP is 2003:0:0:1::4, but shall be one from [u'2003:0:0:1::2', '2003:0:0:1::3']

Expected results: tests pass fine


Additional info: same failure was observed and fixed for newer versions (see linked bug)

Comment 1 Bernard Cafarelli 2017-06-09 08:02:05 UTC

Sorry, I misread #1384631 this is not the same bug

Comment 12 Martin Kopec 2017-06-30 07:21:32 UTC

The openstack-tempest-kilo-20151020.2.el7ost package contains backported code, so marking this as verified.
