-Tempest Field Guide to Baremetal API tests
-==========================================
-
-
-What are these tests?
----------------------
-
-These tests stress the OpenStack baremetal provisioning API provided by
-Ironic.
-
-
-Why are these tests in tempest?
-------------------------------
-
-The purpose of these tests is to exercise the various APIs provided by Ironic
-for managing baremetal nodes.
-
-
-Scope of these tests
---------------------
-
-The baremetal API test perform basic CRUD operations on the Ironic node
-inventory.  They do not actually perform hardware provisioning. It is important
-to note that all Ironic API actions are admin operations meant to be used
-either by cloud operators or other OpenStack services (i.e., Nova).
