I was able to narrow down to the scenario where it fails only when i do:
./run_tests.sh -N cinder.tests.unit.test_remotefs
cinder.tests.unit.test_volume.VolumeTestCase
and fails with:
{0}
cinder.tests.unit.test_volume.VolumeTestCase.test_can_delete_errored_snapshot
[0.507361s] ... FAILED
Captured traceback:
~~~~~~~~~~~~~~~~~~~

ValueError: Field `volume_id' cannot be None
Both the testsuites run fine when i run them individually, as in the below
is success:
./run_tests.sh -N cinder.tests.unit.test_remotefs - no errors
./run_tests.sh -N cinder.tests.unit.test_volume.VolumeTestCase - no errors
So i modified my patch @ https://review.openstack.org/#/c/172808/ (Patch
set 6) and
removed all testcase i added in test_remotefs.py except one, so that we
have lesser code to debug/deal with!
See
https://review.openstack.org/#/c/172808/6/cinder/tests/unit/test_remotefs.py
Now when i disable test_create_snapshot_online_success then running both
the suites work,
but when i enable test_create_snapshot_online_success then it fails as
above.
I am unable to figure whats the connection between
test_create_snapshot_online_success
in test_remotefs.py
and VolumeTestCase.test_can_delete_errored_snapshot in test_volume.py
failure
Can someone help here ?
thanx,
deepak
