Previously attach_interface tests in project/instances/tests.py
did not cover the case of attach_interface by port.
This commit adds UT for such cases.
Details:
- The second call of the mocked network_list_for_tenant retured
an empty list. It sounds tricky to change the return value for
network_list_for_tenant() in two calls, but this trick was used
to skip the processing of port_field_data.
This should return a same value for the two calls to test
port_field_data() function.
- To test the behavior of attach_interface by "port",
an unbound port (whose device_owner/device_id of the port is empty)
is required, so this commit adds it to neutron_data.py.
- test_interface_attach_get() covers a list of choices when "By Port"
is selected in the form.
- test_interface_attach_post_by_port() is added.
Related to the addition of an unbound port to neutron_data.py,
the following other tests are adjusted.
They assumed that all non-network ports are owned by servers,
but it is no longer true as an unbound port is added to the test data.
Note that associating an unbound port with a floating IP is a valid
operation in neutron, so there is no problem to adjust UTs.
