VIM compute operations test specification
=========================================

.. toctree::
   :maxdepth: 2

Scope
=====

The VIM compute operations test area evaluates the ability of the system under
test to support VIM compute operations. The test cases documented here are the
compute API test cases in the OpenStack Interop guideline 2016.8 as implemented
by the RefStack client. These test cases will evaluate basic OpenStack (as a VIM)
compute operations, including:

- Image management operations
- Basic support operations
- API version support operations
- Quotas management operations
- Basic server operations
- Volume management operations

Definitions and abbreviations
=============================

The following terms and abbreviations are used in conjunction with this test area

- API - Application Programming Interface
- NFVi - Network Functions Virtualization infrastructure
- SUT - System Under Test
- UUID - Universally Unique Identifier
- VIM - Virtual Infrastructure Manager
- VM - Virtual Machine

System Under Test (SUT)
=======================

The system under test is assumed to be the NFVi and VIM deployed with a Pharos compliant infrastructure.

Test Area Structure
====================

The test area is structured based on VIM compute API operations. 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.

For brevity, the test cases in this test area are summarized together based on
the operations they are testing.

Pass / fail criteria
''''''''''''''''''''

This test evaluates the functionality of basic server operations.
Specifically, the test verifies that:

* If an admin password is provided on server creation, the server's root password should be set to that password
* Create a server with a name that already exists is allowed
* Create a server with a numeric name or a name that exceeds the length limit is not allowed
* Create a server with a metadata that exceeds the length limit is not allowed
* Create a server with an invalid flavor, an invalid image or an invalid network UUID is not allowed
* Delete a server with a server ID that exceeds the length limit or a nonexistent server ID is not allowed
* A provided server's host name is the same as the server name
* Create a server with an invalid IPv6 access address is not allowed
* A created server is in the (detailed) list of servers
* Filter the (detailed) list of servers by flavor, image, server name, server status,
  and display limit, respectively.
* Filter the list of servers by a future date
* Filter the list of servers by an invalid date format, a negative display limit or a string type
  display limit value is not allowed
* Filter the list of servers by a nonexistent flavor, image, server name or server status is not allowed
* Deleted servers are not in the list of servers
* Deleted servers do not show by default in list of servers
* Locked server is not allowed to be stopped by non-admin user
* Can get and delete metadata from servers
* Can list, set and update server metadata
* Create a server with name parameter empty is not allowed
* Hard reboot a server and the server should be power cycled
* Reboot, rebuild and stop a nonexistent server is not allowed
* Rebuild a server using the provided image and metadata
* Stop and restart a server
* A server's name and access addresses can be updated
* Update the name of a nonexistent server is not allowed
* Update name of a server to a name that exceeds the name length limit is not allowed
* Update name of a server to an empty string is not allowed
* The number of vcpus reported by the server matches the amount stated by the server's flavor
* The specified server attributes are set correctly

In order to pass this test, all test assertions listed in the test execution above need to pass.

* Compute volume extension API

Basic test flow execution description and pass/fail criteria
------------------------------------------------------------

Test execution
''''''''''''''

* Test action 1: Create a server VM1 and a volume VOL1
* Test action 2: Attach VOL1 to VM1
* **Test assertion 1:** Stop VM1 successfully and wait VM1 to reach 'SHUTOFF' status
* **Test assertion 2:** Start VM1 successfully and wait VM1 to reach 'ACTIVE' status
* **Test assertion 3:** SSH into VM1 and verify VOL1 is in VM1's root disk devices
* Test action 3: Detach VOL1 from VM1
* **Test assertion 4:** Stop VM1 successfully and wait VM1 to reach 'SHUTOFF' status
* **Test assertion 5:** Start VM1 successfully and wait VM1 to reach 'ACTIVE' status
* **Test assertion 6:** SSH into VM1 and verify VOL1 is not in VM1's root disk devices
* Test action 4: Create a server VM2 and a volume VOL2
* Test action 5: Attach VOL2 to VM2
* Test action 6: List VM2's volume attachments
* **Test assertion 7:** Verify the length of the list is 1 and VOL2 attachment is in the list
* Test action 7: Retrieve VM2's volume information
* **Test assertion 8:** Verify volume information is correct
* Test action 8: Delete VM1, VM2, VOL1 and VOL2

Pass / fail criteria
