 VIM volume operations test specification
-========================================
+=========================================
 
 .. toctree::
    :maxdepth: 2
 
-Each test case requires documentation according to:
-* Use case specification
-* Test preconditions
-* Basic test flow execution descriptor
-* Post conditions and pass fail criteria
+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.

+
+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.
