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.vm_lifecycle of +OVP test suite. + +Test Descriptions +================= + +---------------------- +API Used and Reference +---------------------- + +Block storage: https://developer.openstack.org/api-ref/block-storage + +- create volume +- delete volume +- attach volume to server +- detach volume from server + +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 +- resize server +- revert resized server +- confirm resized server +- pause server +- unpause server +- start server +- stop server +- reboot server +- rebuild server +- suspend server +- resume suspended server +- shelve server +- unshelve server +- migrate server +- live-migrate server + +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 - Minimum basic scenario +------------------------------------ + +Test case specification +----------------------- + +tempest.scenario.test_minimum_basic.TestMinimumBasicScenario.test_minimum_basic_scenario + +Test preconditions +------------------ + +* Nova, cinder, glance, neutron services are available +* One public network + +Basic test flow execution description and pass/fail criteria +------------------------------------------------------------ + +Test execution +'''''''''''''' + +* Test action 1: Create an image IMG1 +* Test action 2: Create a keypair KEYP1 +* Test action 3: Create a server VM1 with IMG1 and KEYP1 +* **Test assertion 1:** Verify VM1 is created successfully +* Test action 4: Create a volume VOL1 +* **Test assertion 2:** Verify VOL1 is created successfully +* Test action 5: Attach VOL1 to VM1 +* **Test assertion 3:** Verify VOL1's status has been updated after attached to VM1 +* Test action 6: Create a floating IP FIP1 and assign FIP1 to VM1 +* **Test assertion 4:** Verify VM1's addresses have been refreshed after associating FIP1 +* Test action 7: Create and add security group SG1 to VM1 +* **Test assertion 5:** Verify can SSH to VM1 via FIP1 +* Test action 8: Reboot VM1 +* **Test assertion 6:** Verify can SSH to VM1 via FIP1 +* **Test assertion 7:** Verify VM1's disk count equals to 1 +* Test action 9: Delete the floating IP FIP1 from VM1 +* **Test assertion 8:** Verify VM1's addresses have been refreshed after disassociating FIP1 +* Test action 10: Delete SG1, IMG1, KEYP1, VOL1, VM1 and FIP1 + +Pass / fail criteria +'''''''''''''''''''' + +This test evaluates a minimum basic scenario.
