Each test case is able to run independently, i.e. irrelevant of +the state created by a previous test. Specifically, every test performs clean-up +operations which return the system to the same state as before the test. + +All these test cases are included in the test case dovetail.tempest.multi_node_scheduling of +OVP test suite. + +Test Descriptions +================= + +---------------------- +API Used and Reference +---------------------- + +Security Groups: https://developer.openstack.org/api-ref/network/v2/index.html#security-groups-security-groups + +- create security group +- delete security group + +Networks: https://developer.openstack.org/api-ref/networking/v2/index.html#networks + +- create network +- delete network + +Routers and interface: https://developer.openstack.org/api-ref/networking/v2/index.html#routers-routers + +- create router +- delete router +- add interface to router + +Subnets: https://developer.openstack.org/api-ref/networking/v2/index.html#subnets + +- create subnet +- delete subnet + +Servers: https://developer.openstack.org/api-ref/compute/ + +- create keypair +- create server +- show server +- delete server +- add/assign floating IP +- create server group +- delete server group +- list server groups +- show server group details + +Ports: https://developer.openstack.org/api-ref/networking/v2/index.html#ports + +- create port +- delete port + +Floating IPs: https://developer.openstack.org/api-ref/networking/v2/index.html#floating-ips-floatingips + +- create floating IP +- delete floating IP + +Availability zone: https://developer.openstack.org/api-ref/compute/ + +- get availability zone + +------------------------------------------ +Test Case 1 -
