Description: 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 are some features of
          OpenStack that are 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. Where the configuration file lives and how you interact with it
        depends on how you'll be running Tempest. There are 2 methods of using Tempest.
        The first, which is a newer and recommended workflow treats Tempest as a system
        installed program. The second older method is to run Tempest assuming your
        working dir is the actually Tempest source repo, and there are a number of
        assumptions related to that. For this section we'll only cover the newer method
        as it is simpler, and quicker to work with.
        
        #. You first need to install Tempest. This is done with pip after you check out
           the Tempest repo::
        
            $ git clone https://github.com/openstack/tempest/
            $ pip install tempest/
        
           This can be done within a venv, but the assumption for this guide is that
           the Tempest cli entry point will be in your shell's PATH.
        
        #. Installing Tempest will create a /etc/tempest dir which will contain the
           sample config file packaged with Tempest. The contents of /etc/tempest will
           be copied to all local working dirs, so if there is any common configuration
           you'd like to be shared between anyone setting up local Tempest working dirs
           it's recommended that you copy or rename tempest.conf.sample to tempest.conf
           and make those changes to that file in /etc/tempest
        
        #. Setup a local working Tempest dir. This is done using the tempest init
           command::
        
            tempest init cloud-01
        
           works the same as::
        
            mkdir cloud-01 && cd cloud-01 && tempest init
        
           This will create a new directory for running a single Tempest configuration.
           If you'd like to run Tempest against multiple OpenStack deployments the idea
           is that you'll create a new working directory for each to maintain separate
           configuration files and local artifact storage for each.
        
        #. Then cd into the newly created working dir and also modify the local
           config files located in the etc/ subdir created by the ``tempest init``
           command. Tempest is expecting a tempest.conf file in etc/ so if only a
           sample exists you must rename or copy it to tempest.conf before making
           any changes to it otherwise Tempest will not know how to load it.
        
        #. Once the configuration is done you're now ready to run Tempest. This can
           be done with testr directly or any `testr`_ based test runner, like
           `ostestr`_. For example, from the working dir running::
        
             $ ostestr --regex '(?!.*\[.*\bslow\b.*\])(^tempest\.(api|scenario))'
        
           will run the same set of tests as the default gate jobs.

        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 specifying 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 py27 and py34 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)
        
        Python 3.4
        ----------
        
        Starting during the Liberty release development cycle work began on enabling
        Tempest to run under both Python 2.7 and Python 3.4. Tempest strives to fully
        support running with Python 3.4. A gating unit test job was added to also run
        Tempest's unit tests under Python 3.4. This means that the Tempest code at
        least imports under Python 3.4 and things that have unit test coverage will
        work on Python 3.4. However, because large parts of Tempest are self-verifying
        there might be uncaught issues running on Python 3.4. So until there is a gating
        job which does a full Tempest run using Python 3.4 there isn't any guarantee
        that running Tempest under Python 3.4 is bug free.
        
        Legacy run method
        -----------------
        
        The legacy method of running Tempest is to just treat the Tempest source code
        as a python unittest repository and run directly from the source repo. When
        running in this way you still start with a Tempest config file and the steps
        are basically the same except that it expects you know where the Tempest code
        lives on your system and requires a bit more manual interaction to get Tempest
        running. For example, when running Tempest this way things like a lock file
        directory do not get generated automatically and the burden is on the user to
        create and configure that.
        
        To start you need to create a configuration file. The easiest way to create a
        configuration file is to generate a sample in the ``etc/`` directory ::
        
            $> cd $TEMPEST_ROOT_DIR
            $> oslo-config-generator --config-file \
                etc/config-generator.tempest.conf \
                --output-file 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
        
        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.
