Hi,

Ensure that stdout isn't captured by the corresponding fixture:

OS_STDOUT_CAPTURE=0 python -m testtools.run
neutron.tests.unit.openvswitch.test_ovs_neutron_agent.TestOvsNeutronAgent.test_port_update
Tests running...
>
/home/rpodolyaka/src/neutron/neutron/tests/unit/openvswitch/test_ovs_neutron_agent.py(251)test_port_update()
    250
--> 251         with contextlib.nested(
    252             mock.patch.object(self.agent.int_br,
"get_vif_port_by_id"),


OS_STDOUT_CAPTURE=1 python -m testtools.run
neutron.tests.unit.openvswitch.test_ovs_neutron_agent.TestOvsNeutronAgent.test_port_update
Tests running...
======================================================================
ERROR:
neutron.tests.unit.openvswitch.test_ovs_neutron_agent.TestOvsNeutronAgent.test_port_update
----------------------------------------------------------------------
Empty attachments:

  stdout

Traceback (most recent call last):
  File "neutron/tests/unit/openvswitch/test_ovs_neutron_agent.py", line

(....)

AttributeError: '_io.BytesIO' object has no attribute 'name'

Thanks,
Roman
