+Reviewing Tempest Code
+======================
+
+To start read the `OpenStack Common Review Checklist
+<https://wiki.openstack.org/wiki/ReviewChecklist#Common_Review_Checklist>`_
+
+
+Ensuring code is executed
+-------------------------
+
+For any new or change to a test it has to be verified in the gate. This means
+that the first thing to check with any change is that a gate job actually runs
+it. Tests which aren't executed either because of configuration or skips should
+not be accepted.
+
+
+Unit Tests
+----------
+
+For any change that adds new functionality to either common functionality or an
+out-of-band tool unit tests are required. This is to ensure we don't introduce
+future regressions and to test conditions which we may not hit in the gate runs.
+Tests, and service clients aren't required to have unit tests since they should
+be self verifying by running them in the gate.
+
+
+API Stability
+-------------
+Tests should only be added for a published stable APIs. If a patch contains
+tests for an API which hasn't been marked as stable or for an API that which
+doesn't conform to the `API stability guidelines
+<https://wiki.openstack.org/wiki/Governance/Approved/APIStability>`_ then it
+should not be approved.
+
+
+Reject Copy and Paste Test Code
+------------------------
+When creating new tests that are similar to existing tests it is tempting to
+simply copy the code and make a few modifications. This increases code size and
+the maintenance burden. Such changes should not be approved if it is easy to
+abstract the duplicated code into a function or method.
+
+
+Being explicit
+--------------
+When tests are being added that depend on a configurable feature or extension,
+polling the API to discover that it is enabled should not be done. This will
+just result in bugs being masked because the test can be skipped automatically.
+Instead the config file should be used to determine whether a test should be
+skipped or not. Do not approve changes that depend on an API call to determine
+whether to skip or not.
+
+
+When to approve
+---------------
+ * Every patch needs two +2s before being approved.
+ * Its ok to hold off on an approval until a subject matter expert reviews it
+ * If a patch has already been approved but requires a trivial rebase to merge,
+   you do not have to wait for a second +2, since the patch has already had
+   two +2s.
