1. Problem:
test_list_servers_filtered_by_ip sometimes fails with:
Traceback (most recent call last):
File "/home/zfl/tempest_m_git_local/tempest/api/compute/servers/test_list_server_filters.py", line 284, in test_list_servers_filtered_by_ip
self.assertNotIn(self.s2_name, map(lambda x: x['name'], servers))
File "/usr/lib/python2.7/site-packages/testtools/testcase.py", line 392, in assertNotIn
self.assertThat(haystack, matcher, message)
File "/usr/lib/python2.7/site-packages/testtools/testcase.py", line 433, in assertThat
raise mismatch_error
MismatchError: [u'tempest-ListServerFiltersTestJSON-instance-328761420'] matches Contains('tempest-ListServerFiltersTestJSON-instance-328761420')
2. Reason:
We can see from nova code that filter by ip is always "regexp match", so if server2' ip happened to be part of
server1's ip, then filter by server1's ip will also return server2.

3. Solution:
There are 3 possibles ways,
1) create servers with specified ips, such as 1.1.1.1, 1.1.1.2, 1.1.1.3
2) find the longest ip in servers, and filter it by that ip, then only one server will be returned
3) filter using server1's ip, and using assertIn or assertNotIn according to whether other server ip is part of server1's ip |
