+OpenStack Test Driver
+=====================
+
+This is a fake driver for Senlin test. All interactions between Senlin
+and backend OpenStack services, like Nova, Heat are simulated using this
+driver. With it, Senlin API and engine workflow can be easily tested
+without setting up backend services.
+
+Configure the following option in senlin.conf to enable this driver:
+
+    `cloud_backend = openstack_test`
