As Tempest and plugins master version is used to test the supported stable branches, we need to test them on master gate. Adding document for that so that we can test the stable branches more consistently on plugins side too. Change-Id: Ied3c6bb4032fd3740ae0d6d185e4a138fd335b02

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.
