+Stable Branch Testing Policy
+============================
+
+Tempest and its plugins need to support the stable branches
+as per :doc:`Stable Branch Support Policy </stable_branch_support_policy>`.
+
+Because of branchless model of Tempest and plugins, all the supported
+stable branches use the Tempest and plugins master version for their
+testing. That is done in devstack by using the `master branch
+<https://opendev.org/openstack/devstack/src/commit/c104afec7dd72edfd909847bee9c14eaf077a28b/stackrc#L314>`_
+for the Tempest installation. To make sure the master version of Tempest or
+plugins (for any changes or adding new tests) is compatible for all
+the supported stable branches testing, Tempest and its plugins need to
+add the stable branches job on the master gate. That way can test the stable
+branches against master code and can avoid breaking supported branches
+accidentally.
+
+Example:
+
+* `Stable jobs on Tempest master
+  <https://opendev.org/openstack/tempest/src/commit/e8f1876aa6772077f85f380677b30251c2454505/.zuul.yaml#L646-L651>`_.
+
+* `Stable job on neutron tempest plugins
+  <https://opendev.org/openstack/neutron-tempest-plugin/src/commit/4bc1b00213cf660648cad1916fe6497ac29b2e78/.zuul.yaml#L1427-L1428>`_
+
+Once any stable branch is moved to the `Extended Maintenance Phases`_
+and devstack start using the Tempest older version for that stable
+branch testing then we can remove that stable branch job from master
+gate.

+
+   The devstack base directory.
+
+.. zuul:rolevar:: init_saved_state
+   :default: false
+
+   When true, tempest cleanup --init-saved-state will be executed which
+   initializes the saved state of the OpenStack deployment and will output
+   a saved_state.json file containing resources from the deployment that will
+   be preserved from the cleanup command. This should be done prior to running
+   Tempest tests.
+
+.. zuul:rolevar:: dry_run
+   :default: false
+
+   When true, tempest cleanup creates a report (./dry_run.json) of the
+   resources that would be cleaned up if the role was ran with dry_run option
+   set to false.
