running local tests fails in oslo_policy package

[Mathieu Rohon]

When I run tests localy with ./run_tests.sh or tox -e py27, it constantly fails in the oslo_policy package.

For instance :

$ ./run_tests.sh neutron.tests.unit.extensions.test_securitygroup.TestSecurityGroups.test_create_security_group_rule_bad_tenant_security_group_rule

Running `tools/with_venv.sh python setup.py testr --slowest --testr-args='--subunit neutron.tests.unit.extensions.test_securitygroup.TestSecurityGroups.test_create_security_group_rule_bad_tenant_security_group_rule'`
running testr

Fix proposed to branch: master
Review: https://review.openstack.org/212571

[Mathieu Rohon (mathieu-rohon)]

I removed the /etc/neutron.policy.d on my system, and it works fine now. However, even if I recreate the /etc/neutron/policy.d, tests don't fail anymore. I Don't understand what happened

[Ihar Hrachyshka (ihar-hrachyshka)]

It seems that our attempt to isolate unit tests from oslo.config autodiscovery is not complete. I reported a separate bug to adopt the fixture that should make it for us: https://bugs.launchpad.net/neutron/+bug/1485537
