tempest failure: test_list_agent failes with MismatchError

[Itsuro Oda]

Jenkins job 'check-tempest-dsvm-neutron-pg-isolated' failed when I posted a fix.
(see. http://logs.openstack.org/34/65034/1/check/check-tempest-dsvm-neutron-pg-isolated/d3e37ea )

Failed test is as follows:
---
 FAIL: tempest.api.network.admin.test_agent_management.AgentManagementTestJSON.test_list_agent[gate,smoke]
 tempest.api.network.admin.test_agent_management.AgentManagementTestJSON.test_list_agent[gate,smoke]

 Traceback (most recent call last):

 MismatchError: {u'binary': u'neutron-dhcp-agent', u'description': None, ... snip

I found the mismatch is only 'heartbeat_timestamp'.
expected: u'heartbeat_timestamp': u'2014-01-06 06:52:48.291601'
real: u'heartbeat_timestamp': u'2014-01-06 06:52:52.309330'

In test_list_agent GET API issues twice and compare results.
It is possible to differ heartbeat_timestam isn't it?

[shihanzhang (shihanzhang)]

I think the heartbeat_timestam should not be difffered,but the body that agent_list return includes heartbeat_timestam,so it should remove the heartbeat_timestam before using "assertIn"

It seem it should affect tempest only.

This will fix part of the check-tempest-dsvm-neutron-pg-isolated failures.

This hasn't been seen in two weeks, marking as resolved.
