| 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. |
