The cli tests have been marked for removal for ~6 months and the framework was the first thing included in tempest lib. There has been more than enough time for all the projects to pick this up in the client repos. So let's remove it all! As part of this a couple of missing entries for tempest's requirements.txt were found. These dependencies were being installed by the clients so the fact they were missing was never noticed prior to this. This commit also adds these missing entries back into the requirements file.

Tempest - The OpenStack Integration Test Suite
|
|
==============================================
|
|
|
|
This is a set of integration tests to be run against a live OpenStack
|
|
cluster. Tempest has batteries of tests for OpenStack API validation,
|
|
Scenarios, and other specific tests useful in validating an OpenStack
|
|
deployment.
|
|
|
|
Design Principles
|
|
-----------------
|
|
Tempest Design Principles that we strive to live by.
|
|
|
|
- Tempest should be able to run against any OpenStack cloud, be it a
|
|
one node devstack install, a 20 node lxc cloud, or a 1000 node kvm
|
|
cloud.
|
|
- Tempest should be explicit in testing features. It is easy to auto
|
|
discover features of a cloud incorrectly, and give people an
|
|
incorrect assessment of their cloud. Explicit is always better.
|
|
- Tempest uses OpenStack public interfaces. Tests in Tempest should
|
|
only touch public interfaces, API calls (native or 3rd party),
|
|
or libraries.
|
|
- Tempest should not touch private or implementation specific
|
|
interfaces. This means not directly going to the database, not
|
|
directly hitting the hypervisors, not testing extensions not
|
|
included in the OpenStack base. If there is some feature of
|
|
OpenStack that is not verifiable through standard interfaces, this
|
|
should be considered a possible enhancement.
|
|
- Tempest strives for complete coverage of the OpenStack API and
|
|
common scenarios that demonstrate a working cloud.
|
|
- Tempest drives load in an OpenStack cloud. By including a broad
|
|
array of API and scenario tests Tempest can be reused in whole or in
|
|
parts as load generation for an OpenStack cloud.
|
|
- Tempest should attempt to clean up after itself, whenever possible
|
|
we should tear down resources when done.
|
|
- Tempest should be self testing.
|
|
|
|
Quickstart
|
|
----------
|
|
|
|
To run Tempest, you first need to create a configuration file that
|
|
will tell Tempest where to find the various OpenStack services and
|
|
other testing behavior switches.
|
|
|
|
The easiest way to create a configuration file is to copy the sample
|
|
one in the ``etc/`` directory ::
|
|
|
|
$> cd $TEMPEST_ROOT_DIR
|
|
$> cp etc/tempest.conf.sample etc/tempest.conf
|
|
|
|
After that, open up the ``etc/tempest.conf`` file and edit the
|
|
configuration variables to match valid data in your environment.
|
|
This includes your Keystone endpoint, a valid user and credentials,
|
|
and reference data to be used in testing.
|
|
|
|
.. note::
|
|
|
|
If you have a running devstack environment, Tempest will be
|
|
automatically configured and placed in ``/opt/stack/tempest``. It
|
|
will have a configuration file already set up to work with your
|
|
devstack installation.
|
|
|
|
Tempest is not tied to any single test runner, but `testr`_ is the most commonly
|
|
used tool. Also, the nosetests test runner is **not** recommended to run Tempest.
|
|
|
|
After setting up your configuration file, you can execute the set of Tempest
|
|
tests by using ``testr`` ::
|
|
|
|
$> testr run --parallel
|
|
|
|
.. _testr: http://testrepository.readthedocs.org/en/latest/MANUAL.html
|
|
|
|
To run one single test serially ::
|
|
|
|
$> testr run tempest.api.compute.servers.test_servers_negative.ServersNegativeTestJSON.test_reboot_non_existent_server
|
|
|
|
Alternatively, you can use the run_tempest.sh script which will create a venv
|
|
and run the tests or use tox to do the same. Tox also contains several existing
|
|
job configurations. For example::
|
|
|
|
$> tox -efull
|
|
|
|
which will run the same set of tests as the OpenStack gate. (it's exactly how
|
|
the gate invokes Tempest) Or::
|
|
|
|
$> tox -esmoke
|
|
|
|
to run the tests tagged as smoke.
|
|
|
|
|
|
Configuration
|
|
-------------
|
|
|
|
Detailed configuration of Tempest is beyond the scope of this
|
|
document see :ref:`tempest-configuration` for more details on configuring
|
|
Tempest. The etc/tempest.conf.sample attempts to be a self documenting version
|
|
of the configuration.
|
|
|
|
You can generate a new sample tempest.conf file, run the following
|
|
command from the top level of the Tempest directory:
|
|
|
|
tox -egenconfig
|
|
|
|
The most important pieces that are needed are the user ids, openstack
|
|
endpoint, and basic flavors and images needed to run tests.
|
|
|
|
Unit Tests
|
|
----------
|
|
|
|
Tempest also has a set of unit tests which test the Tempest code itself. These
|
|
tests can be run by specifing the test discovery path::
|
|
|
|
$> OS_TEST_PATH=./tempest/tests testr run --parallel
|
|
|
|
By setting OS_TEST_PATH to ./tempest/tests it specifies that test discover
|
|
should only be run on the unit test directory. The default value of OS_TEST_PATH
|
|
is OS_TEST_PATH=./tempest/test_discover which will only run test discover on the
|
|
Tempest suite.
|
|
|
|
Alternatively, you can use the run_tests.sh script which will create a venv and
|
|
run the unit tests. There are also the py26, py27, or py33 tox jobs which will
|
|
run the unit tests with the corresponding version of python.
|
|
|
|
Python 2.6
|
|
----------
|
|
|
|
Starting in the kilo release the OpenStack services dropped all support for
|
|
python 2.6. This change has been mirrored in Tempest, starting after the
|
|
tempest-2 tag. This means that proposed changes to Tempest which only fix
|
|
python 2.6 compatibility will be rejected, and moving forward more features not
|
|
present in python 2.6 will be used. If you're running your OpenStack services
|
|
on an earlier release with python 2.6 you can easily run Tempest against it
|
|
from a remote system running python 2.7. (or deploy a cloud guest in your cloud
|
|
that has python 2.7)
