It isn't used for some time anymore and doesn't pass, so lets remove the mentioning of it. Change-Id: I9d8e319c9621fa37c1beefe46db4e4d6368acfb9

Devstack Gate
|
|
#############
|
|
|
|
Devstack-gate is a collection of scripts used by the OpenStack CI team
|
|
to test every change to core OpenStack projects by deploying OpenStack
|
|
via devstack on a cloud server.

Overview
|
|
========
|
|
|
|
All changes to core OpenStack projects are "gated" on a set of tests
|
|
so that it will not be merged into the main repository unless it
|
|
passes all of the configured tests. Most projects require unit tests
|
|
with pep8 and several versions of Python. Those tests are all run only
|
|
on the project in question. The devstack gate test, however, is an
|
|
integration test and ensures that a proposed change still enables
|
|
several of the projects to work together. Any proposed change to the
|
|
configured set of projects must pass the devstack gate test.
|
|
|
|
Obviously we test nova, glance, keystone, horizon, neutron and their
|
|
clients because they all work closely together to form an OpenStack
|
|
system. Changes to devstack itself are also required to pass this test
|
|
so that we can be assured that devstack is always able to produce a
|
|
system capable of testing the next change to nova. The devstack gate
|
|
scripts themselves are included for the same reason.
|
|
|
|
How It Works
|
|
============
|
|
|
|
The devstack test starts with an essentially bare virtual machine
|
|
made available by :ref:`nodepool` and prepares the testing
|
|
environment. This is driven by the the devstack-gate repository which
|
|
holds several scripts that are run by Jenkins.
|
|
|
|
When a proposed change is approved by the core reviewers, Jenkins
|
|
triggers the devstack gate test itself. This job runs on one of the
|
|
previously configured nodes and invokes the devstack-vm-gate-wrap.sh
|
|
script which checks out code from all of the involved repositories, and
|
|
merges the proposed change. That script then calls devstack-vm-gate.sh
|
|
which installs a devstack configuration file, and invokes devstack. Once
|
|
devstack is finished, it runs Tempest, which performs integration testing.
|
|
After everything is done, devstack-gate copies and formats all of the logs
|
|
for archival. A jenkins jobs then copies these logs to the log archive.
