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.
