# NOTE(geguileo): For v3 we cannot mock any of the following methods
#   - utils.find_volume
#   - shell_utils.find_backup
#   - shell_utils.find_volume_snapshot
#   - shell_utils.find_group
#   - shell_utils.find_group_snapshot
# because we are caching them in cinderclient.v3.shell:RESET_STATE_RESOURCES
# which means that our tests could fail depending on the mocking and loading
# order.
#
# Alternatives are:
#   - Mock utils.find_resource when we have only 1 call to that method
#   - Use an auxiliary method that will call original method for irrelevant
#     calls.  Example from test_revert_to_snapshot:
#         original = client_utils.find_resource
#
#         def find_resource(manager, name_or_id, **kwargs):
#             if isinstance(manager, volume_snapshots.SnapshotManager):
#                 return volume_snapshots.Snapshot(self,
#                                                  {'id': '5678',
#                                                   'volume_id': '1234'})
#             return original(manager, name_or_id, **kwargs)
