This module defines a base test case that uses testscenarios to
|
|
parametize the test methods of subclasses by varying the client
|
|
fixture used to target the Neutron API.
|
|
|
|
PluginClientFixture targets the Neutron API directly via the plugin
|
|
api, and will be executed by default. testscenarios will ensure that
|
|
each test is run against all plugins defined in plugin_configurations.
|
|
|
|
RestClientFixture targets a deployed Neutron daemon, and will be used
|
|
instead of PluginClientFixture only if OS_TEST_API_WITH_REST is set to 1.
