VIM volume operations test specification
=========================================

.. toctree::
   :maxdepth: 2

Scope
=====

The VIM volume operations test area evaluates the ability of the system under
test to support VIM volume operations. The test cases documented here are the
volume 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)
volume operations, including:

- Volume attach and detach operations
- Volume service availability zone operations
- Volume cloning operations
- Image copy-to-volume operations
- Volume creation and deletion operations
- Volume service extension listing
- Volume metadata operations
- Volume snapshot 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
- 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 volume 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.

All these test cases are included in the test case dovetail.osinterop.tc001 of
OVP test suite.

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

This test case evaluates the volume API ability of managing snapshot and snapshot metadata.
Specifically, the test verifies that:

* Create metadata for snapshot successfully.
* Get metadata of snapshot successfully.
* Update snapshot metadata and metadata item successfully.
* Delete metadata item of a snapshot successfully.
* Create a volume from a nonexistent snapshot is not allowed.
* Delete a volume using an invalid volume ID is not allowed.
* Delete a volume without passing the volume ID is not allowed.
* Delete a non-existent volume is not allowed.
* Create snapshot successfully.
* Get snapshot's detail information successfully.
* Update snapshot attributes successfully.
* Delete snapshot successfully.
* Creates a volume and a snapshot passing a size different from the source successfully.
* List snapshot details by display_name and status filters successfully.
* Create a snapshot from a nonexistent volume is not allowed.
* Create a snapshot from a volume without passing the volume ID is not allowed.

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