+Scope
+=====
+
+The VIM image test area evaluates the ability of the system under test to support
+VIM image operations. The test cases documented here are the Image 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) image operations including
+image creation, image list, image update and image deletion capabilities using Glance v2 API.

+Definitions and abbreviations
+=============================
+
+The following terms and abbreviations are used in conjunction with this test area
+
+- API - Application Programming Interface
+- CRUD - Create, Read, Update, and Delete
+- NFVi - Network Functions Virtualization infrastructure
+- VIM - Virtual Infrastructure Manager
+
+System Under Test (SUT)
+=======================
+
+The system under test is assumed to be the NFVi and VIM in operation on a
+Pharos compliant infrastructure.
+
+Test Area Structure
+====================
+
+The test area is structured based on VIM image operations. Each test case is able
+to run independently, i.e. irrelevant of the state created by a previous test.
+
+For brevity, the test cases in this test area are summarized together based on
+the operations they are testing.

+  its id. Delete this deleted image again with its id and check the API's response code.
+* **Test assertion 3:** The operations of showing and deleting a deleted image with its id
+  both get 404 response code.
+* Test action 5: Use a null image id to show a image and check the API's response code.
+* **Test assertion 4:** The API's response code is 404.
+* Test action 6: Generate a random uuid and use it as the image id to show the image.

+The first two test cases evaluate the ability to use Glance v2 API to show image
+and images schema. The latter three test cases evaluate the ability to use Glance
+v2 API to show images with a deleted image id, a null image id and a non-existing
+image id. Specifically it verifies that:
+
+* Glance image get API can show the image and images schema.
+* Glance image get API can't show an image with a deleted image id.
+* Glance image get API can't show an image with a null image id.
+* Glance image get API can't show an image with a non-existing image id.
