-------------------------------------------
Summary: [Automation] Utility function to care of Errors due to
possible empty list assignments
Key: CLOUDSTACK-4972
URL: https://issues.apache.org/jira/browse/CLOUDSTACK-4972
Project: CloudStack
Issue Type: Test
Security Level: Public (Anyone can view this level - this is the default.)
Components: Automation, marvin
Affects Versions: 4.2.0
Environment: Marvin, Test scripts
Reporter: Sowmya Krishnan
Presently with Test scripts written using Marvin, most tests don't have to
perform an explicit check each time there's a list API call followed by an
assignment of the first object of the list to a variable. There is no check
presently done to find out if the list returns an empty result either.
Tracking bug to create a utility function to take care of possible empty list
assignment and throw appropriate error if this happens.
Example code
networks = Network.list(
self.apiclient,
id=network.id,
listall=True
)
self.assertEqual(
isinstance(networks, list),
True,
"List networks should return a valid response"
)
nw = networks[0]
An empty list assignment would probably just throw an exception and debugging
is difficult when lot of tests are being run.
Comments on better ways to handle this are welcome.
