Closes-Bug: #1190621
This fix improves test code coverage for the file:
neutron/plugins/cisco/network_plugin.py
from 34% to 98%.
Some of the changes made to realize this code coverage improvements
are the following:
- Core API methods (create_network, update_network, etc.) have been
removed from the core plugin (network_plugin.py). These methods
are currently unused. Before this change, we relied on the underlying
model layer to inform the core plugin whether or not the model layer
was capable of handling these core API calls itself via a 'MANAGE_STATE'
attribute. However, there is only one existing model layer
implementation (i.e. for Nexus plugin; the N1KV plugin does not use
network_plugin.py), and that model layer supports the core API calls.
Given that it is unlikely that another model layer for the Cisco Nexus
plugin will ever be developed (esp. with the availability of the ML2
plugin), so it makes more sense to delete this untested code.
- Exception raising for non-existent credentials has been removed from
get_credential_details and rename_credential methods since
exceptions are already raised for this condition in lower-level
credential database code.
- The schedule_host, associate_port, and detach_port methods are
deleted because these essentially do nothing useful (log a debug
message and then return None), since these methods look for
the same-named methods in the model layer, but these methods are
not defined in the model layer.
- The helper functions _invoke_device_plugins and _func_name are
deleted because they are no longer used.
- In unit test code for the Cisco QoS and credentials database, calls
are now made indirectly through the core plugin (network_plugin.py)
extension API methods, as a quick-and-easy way to provide code
coverage for these core plugin methods.
