 Tempest - The OpenStack Integration Test Suite
 ==============================================
 
-The documentation for Tempest is officially hosted at:
-https://docs.openstack.org/tempest/latest/
-
 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.
+  * Documentation: https://docs.openstack.org/tempest/latest/
+  * Features: https://specs.openstack.org/openstack/qa-specs/#tempest
+  * Bugs: https://bugs.launchpad.net/tempest/
+  * Release Notes: https://docs.openstack.org/releasenotes/tempest
 
-- 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 OpenStack APIs.
-- 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://opendev.org/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 may create a ``/etc/tempest dir``, however if one isn't
-   created you can create one or use ``~/.tempest/etc`` or ``~/.config/tempest`` in
-   place of ``/etc/tempest``. If none of these dirs are created Tempest will create
-   ``~/.tempest/etc`` when it's needed. The contents of this dir will always
-   automatically be copied to all ``etc/`` dirs in local workspaces as an initial
-   setup step. So if there is any common configuration you'd like to be shared
-   between local Tempest workspaces it's recommended that you pre-populate it
-   before running ``tempest init``.
-
-#. Setup a local Tempest workspace. This is done by using the tempest init
-   command::
-
-    $ tempest init cloud-01
-
-   which also 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. For
-   details on configuring Tempest refer to the
-   `Tempest Configuration <https://docs.openstack.org/tempest/latest/configuration.html#tempest-configuration>`_
-
-#. Once the configuration is done you're now ready to run Tempest. This can
-   be done using the `Tempest Run <https://docs.openstack.org/tempest/latest/run.html#tempest-run>`_
-   command. This can be done by either
-   running::
-
-    $ tempest run
-
-   from the Tempest workspace directory. Or you can use the ``--workspace``
-   argument to run in the workspace you created regardless of your current
-   working directory. For example::
-
-    $ tempest run --workspace cloud-01
-
-   There is also the option to use `stestr`_ directly. For example, from
-   the workspace dir run::
-
-    $ stestr run --black-regex '\[.*\bslow\b.*\]' '^tempest\.(api|scenario)'
-
-   will run the same set of tests as the default gate jobs. Or you can
-   use `unittest`_ compatible test runners such as `testr`_, `pytest`_ etc.
-
-   Tox also contains several existing job configurations. For example::
-
-    $ tox -e full
-
-   which will run the same set of tests as the OpenStack gate. (it's exactly how
-   the gate invokes Tempest) Or::
-
-    $ tox -e smoke
-
-   to run the tests tagged as smoke.

-
-Library
--------
-Tempest exposes a library interface. This interface is a stable interface and
-should be backwards compatible (including backwards compatibility with the
-old tempest-lib package, with the exception of the import). If you plan to
-directly consume Tempest in your project you should only import code from the
-Tempest library interface, other pieces of Tempest do not have the same
-stable interface and there are no guarantees on the Python API unless otherwise
-stated.
-
-For more details refer to the `library documentation
-<https://docs.openstack.org/tempest/latest/library.html#library>`_
-
-Release Versioning
-------------------
-`Tempest Release Notes <https://docs.openstack.org/releasenotes/tempest>`_
-shows what changes have been released on each version.
-
-Tempest's released versions are broken into 2 sets of information. Depending on
-how you intend to consume Tempest you might need
-
-The version is a set of 3 numbers:
-
-X.Y.Z
-
-While this is almost `semver`_ like, the way versioning is handled is slightly
-different:
-
-X is used to represent the supported OpenStack releases for Tempest tests
-in-tree, and to signify major feature changes to Tempest. It's a monotonically
-increasing integer where each version either indicates a new supported OpenStack
-release, the drop of support for an OpenStack release (which will coincide with
-the upstream stable branch going EOL), or a major feature lands (or is removed)
-from Tempest.
-
-Y.Z is used to represent library interface changes. This is treated the same
-way as minor and patch versions from `semver`_ but only for the library
-interface. When Y is incremented we've added functionality to the library
-interface and when Z is incremented it's a bug fix release for the library.
-Also note that both Y and Z are reset to 0 at each increment of X.
-
-.. _semver: https://semver.org/
-
-Configuration
--------------
-
-Detailed configuration of Tempest is beyond the scope of this
-document, see `Tempest Configuration Documentation
-<https://docs.openstack.org/tempest/latest/configuration.html#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 -e genconfig
-
-The most important pieces that are needed are the user ids, OpenStack
-endpoints, 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::
-
-    $ stestr --test-path ./tempest/tests run
-
-By setting ``--test-path`` option to ./tempest/tests it specifies that test discover
-should only be run on the unit test directory. The default value of ``test_path``
-is ``test_path=./tempest/test_discover`` which will only run test discover on the
-Tempest suite.
-
-Alternatively, there are the py27 and py36 tox jobs which will run the unit
-tests with the corresponding version of python.
-
-One common activity is to just run a single test, you can do this with tox
-simply by specifying to just run py27 or py36 tests against a single test::
-
-    $ tox -e py36 -- -n tempest.tests.test_microversions.TestMicroversionsTestsClass.test_config_version_none_23
-
-Or all tests in the test_microversions.py file::
-
-    $ tox -e py36 -- -n tempest.tests.test_microversions
-
-You may also use regular expressions to run any matching tests::
-
-    $ tox -e py36 -- test_microversions
-
-Additionally, when running a single test, or test-file, the ``-n/--no-discover``
-argument is no longer required, however it may perform faster if included.
-
-For more information on these options and details about stestr, please see the
-`stestr documentation <https://stestr.readthedocs.io/en/latest/MANUAL.html>`_.
-
-Python 3.x
-----------
-
-Starting during the Pike cycle Tempest has a gating CI job that runs Tempest
-with Python 3. Any Tempest release after 15.0.0 should fully support running
-under Python 3 as well as Python 2.7.
-
-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 \
-        tempest/cmd/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

+
+The documentation for Tempest is officially hosted at:

+
+This is a set of integration tests to be run against a live OpenStack

+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 OpenStack APIs.
+- 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://opendev.org/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 may create a ``/etc/tempest dir``, however if one isn't
+   created you can create one or use ``~/.tempest/etc`` or ``~/.config/tempest`` in
+   place of ``/etc/tempest``. If none of these dirs are created Tempest will create
+   ``~/.tempest/etc`` when it's needed. The contents of this dir will always
+   automatically be copied to all ``etc/`` dirs in local workspaces as an initial
+   setup step. So if there is any common configuration you'd like to be shared
+   between local Tempest workspaces it's recommended that you pre-populate it
+   before running ``tempest init``.
+
+#. Setup a local Tempest workspace. This is done by using the tempest init
+   command::
+
+    $ tempest init cloud-01
+
+   which also 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. For
+   details on configuring Tempest refer to the
+   `Tempest Configuration <https://docs.openstack.org/tempest/latest/configuration.html#tempest-configuration>`_
+
+#. Once the configuration is done you're now ready to run Tempest. This can
+   be done using the `Tempest Run <https://docs.openstack.org/tempest/latest/run.html#tempest-run>`_
+   command. This can be done by either
+   running::
+
+    $ tempest run
+
+   from the Tempest workspace directory. Or you can use the ``--workspace``
+   argument to run in the workspace you created regardless of your current
+   working directory. For example::
+
+    $ tempest run --workspace cloud-01
+
+   There is also the option to use `stestr`_ directly. For example, from
+   the workspace dir run::
+
+    $ stestr run --black-regex '\[.*\bslow\b.*\]' '^tempest\.(api|scenario)'
+
+   will run the same set of tests as the default gate jobs. Or you can
+   use `unittest`_ compatible test runners such as `stestr`_, `pytest`_ etc.
+
+   Tox also contains several existing job configurations. For example::
+
+    $ tox -e full
+
+   which will run the same set of tests as the OpenStack gate. (it's exactly how
+   the gate invokes Tempest) Or::
+
+    $ tox -e smoke
+
+   to run the tests tagged as smoke.

+
+Library
+-------
+Tempest exposes a library interface. This interface is a stable interface and
+should be backwards compatible (including backwards compatibility with the
+old tempest-lib package, with the exception of the import). If you plan to
+directly consume Tempest in your project you should only import code from the
+Tempest library interface, other pieces of Tempest do not have the same
+stable interface and there are no guarantees on the Python API unless otherwise
+stated.
+
+For more details refer to the `library documentation
+<https://docs.openstack.org/tempest/latest/library.html#library>`_
+
+Release Versioning
+------------------
+`Tempest Release Notes <https://docs.openstack.org/releasenotes/tempest>`_
+shows what changes have been released on each version.
+
+Tempest's released versions are broken into 2 sets of information. Depending on
+how you intend to consume Tempest you might need
+
+The version is a set of 3 numbers:
+
+X.Y.Z
+
+While this is almost `semver`_ like, the way versioning is handled is slightly
+different:
+
+X is used to represent the supported OpenStack releases for Tempest tests
+in-tree, and to signify major feature changes to Tempest. It's a monotonically
+increasing integer where each version either indicates a new supported OpenStack
+release, the drop of support for an OpenStack release (which will coincide with
+the upstream stable branch going EOL), or a major feature lands (or is removed)
+from Tempest.
+
+Y.Z is used to represent library interface changes. This is treated the same
+way as minor and patch versions from `semver`_ but only for the library
+interface. When Y is incremented we've added functionality to the library
+interface and when Z is incremented it's a bug fix release for the library.
+Also note that both Y and Z are reset to 0 at each increment of X.
+
+.. _semver: https://semver.org/
+
+Configuration
+-------------
+
+Detailed configuration of Tempest is beyond the scope of this
+document, see `Tempest Configuration Documentation
+<https://docs.openstack.org/tempest/latest/configuration.html#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 -e genconfig
+
+The most important pieces that are needed are the user ids, OpenStack
+endpoints, 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::
+
+    $ stestr --test-path ./tempest/tests run
+
+By setting ``--test-path`` option to ./tempest/tests it specifies that test discover
+should only be run on the unit test directory. The default value of ``test_path``
+is ``test_path=./tempest/test_discover`` which will only run test discover on the
+Tempest suite.
+
+Alternatively, there are the py27 and py36 tox jobs which will run the unit
+tests with the corresponding version of python.
+
+One common activity is to just run a single test, you can do this with tox
+simply by specifying to just run py27 or py36 tests against a single test::
+
+    $ tox -e py36 -- -n tempest.tests.test_microversions.TestMicroversionsTestsClass.test_config_version_none_23
+
+Or all tests in the test_microversions.py file::
+
+    $ tox -e py36 -- -n tempest.tests.test_microversions
+
+You may also use regular expressions to run any matching tests::
+
+    $ tox -e py36 -- test_microversions
+
+Additionally, when running a single test, or test-file, the ``-n/--no-discover``
+argument is no longer required, however it may perform faster if included.
+
+For more information on these options and details about stestr, please see the
+`stestr documentation <https://stestr.readthedocs.io/en/latest/MANUAL.html>`_.
+
+Python 3.x
+----------
+
+Starting during the Pike cycle Tempest has a gating CI job that runs Tempest
+with Python 3. Any Tempest release after 15.0.0 should fully support running
+under Python 3 as well as Python 2.7.
+
+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 \
+        tempest/cmd/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 `stestr`_ 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 ``stestr``. By default, ``stestr`` runs tests in parallel ::
+
+    $ stestr run
+
+To run one single test serially ::
+
+    $ stestr run --serial tempest.api.compute.servers.test_servers_negative.ServersNegativeTestJSON.test_reboot_non_existent_server

+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.

+Tempest and Plugins compatible version policy
+=============================================
+
+Tempest and its plugins are responsible for the integrated
+testing of OpenStack. These tools have two use cases:
+
+#. Testing upstream code at gate
+#. Testing Production Cloud
+
+Upstream code is tested by the master version of branchless Tempest & plugins
+for all supported stable branches in `Maintained phase`_.
+
+Production Cloud can be tested by using the compatible version or using
+master version. It depends on the testing strategy of cloud. To provide
+the compatible version of Tempest and its Plugins per OpenStack release,
+we started the coordinated release of all plugins and Tempest per OpenStack
+release.
+These versions are the first set of versions from Tempest and its Plugins to
+officially start the support of a particular OpenStack release. For example:
+OpenStack Train release first compatible versions `Tempest plugins version`_.
+
+Because of branchless nature of Tempest and its plugins, first version
+released during OpenStack release is not the last version to support that
+OpenStack release. This means the next (or master) versions can also be used
+for upstream testing as well as in production testing.
+
+Since the `Extended Maintenance policy`_ for stable branch, Tempest
+started releasing the ``end of support`` version once stable release
+is moved to EM state, which used to happen on EOL of stable release. This is
+the last compatible version of Tempest for the OpenStack release moved to EM.
+
+Because of branchless nature as explained above, we have a range of versions
+which can be considered a compatible version for particular OpenStack release.
+How we should release those versions is mentioned in the below table.
+
+ +-----------------------------+-----------------+------------------------------------+
+ | First compatible version -> | OpenStack 'XYZ' | <- Last compatible version         |
+ +=============================+=================+====================================+
+ |This is the latest version   |                 |This is the version released        |
+ |released when OpenStack      |                 |when OpenStack 'XYZ' is moved to    |
+ |'XYZ' is released.           |                 |EM state. Hash used for this should |
+ |Example:                     |                 |be the hash from master at the time |
+ |`Tempest plugins version`_   |                 |of branch is EM not the one used for|
+ |                             |                 |First compatible version            |
+ +-----------------------------+-----------------+------------------------------------+
+
+Tempest & the Plugins should follow the above mentioned policy for the
+``First compatible version`` and the ``Last compatible version.``
+so that we provide the right set of compatible versions to Upstream as well as to
+Production Cloud testing.

+     from ``RegionOne`` to empty string.
+
+     As per tempest design, if tempest conf is not having any region for
+     a service then identity region should be used. In case of placement
+     the default value is "RegionOne" which is considered as placement
+     region if region missing in tempest conf. In order to have identity
+     region to be used as default we need to change to empty string for
+     placement service. Empty string can be seen being used in other
+     services like volume, image etc.

+
+   When true, tempest cleanup --init-saved-state will be executed which
+   initializes the saved state of the OpenStack deployment and will output
+   a saved_state.json file containing resources from the deployment that will

 by removing unnecessary tests from a list file which is generated from
 ``--list-tests`` option.
 
+You can also use ``--worker-file`` option that let you pass a filepath to a
+worker yaml file, allowing you to manually schedule the tests run.
+For example, you can setup a tempest run with
+different concurrences to be used with different regexps.
+An example of worker file is showed below::
+
+    # YAML Worker file
+    - worker:
+      # you can have more than one regex per worker
+      - tempest.api.*
+      - neutron_tempest_tests
+    - worker:
+      - tempest.scenario.*
+
+This will run test matching with 'tempest.api.*' and 'neutron_tempest_tests'
+against worker 1. Run tests matching with 'tempest.scenario.*' under worker 2.
+
+You can mix manual scheduling with the standard scheduling mechanisms by
+concurrency field on a worker. For example::
+
+    # YAML Worker file
+    - worker:
+      # you can have more than one regex per worker
+      - tempest.api.*
+      - neutron_tempest_tests
+      concurrency: 3
+    - worker:
+      - tempest.scenario.*
+      concurrency: 2
+
+This will run tests matching with 'tempest.scenario.*' against 2 workers.
+
+This worker file is passed into stestr. For some more details on how it
+operates please refer to the stestr scheduling docs:
+https://stestr.readthedocs.io/en/stable/MANUAL.html#test-scheduling
