+Bareon functional testing
+=========================

+
+Problem description
+===================
+
+Currently there are no functional tests in bareon. Tests that would cover full
+on-metal provisioning and a result - actual partition scheme / image applied
+to the node
+
+Proposed change
+===============
+
+NOTE: This is a contribution of the feature developed within Cray OpenStack project.
+We will try to make a minimum changes to existing code.
+
+We are adding the new framework "bareon-func-test" to allow writing such kind
+of tests. This is a virsh-based tool that allows to walk through the full
+provisioning cycle and read the results from the node at each step. An overview
+of the framework can be found at [1]
+
+The framework will reside in a separate repo called "bareon-func-test".
+
+Functional tests, as well as node templates, provision.json templates (if any)
+are stored in the bareon tree (bareon/tests_functional/). The main idea behind
+this is that you can commit the new piece of functionality together with funcitonal
+tests covering it, and it's easier to track in CI.
+
+We are also adding a set of tests covering:
+ - partitioning operations on Ironic data driver
+ - lvm operations on Ironic data driver
+ - full provisioning on both swift/rsync deploy drivers and Ironic data driver.
+
+Since the framework requires a ramdisk to run, test integration also includes
+a job to build a ramdisk from the current repo, and a tox env that manages
+build/test-run.
