-The project contains three test packages, one for unit tests, one for
-functional tests and one for examples tests. The ``openstack.tests.unit``
-package tests the SDK's features in isolation. The
-``openstack.tests.functional`` and ``openstack.tests.examples`` packages test
-the SDK's features and examples against an OpenStack cloud.

-Examples Tests
---------------
-
-Similar to the functional tests, the examples tests assume that you have a
-public or private OpenStack cloud that you can run the tests against. In
-practice, this means that the tests should initially be run against a stable
-branch of `DevStack <https://docs.openstack.org/devstack/latest/>`_.
-And like the functional tests, the examples tests connect to an OpenStack cloud
-using `os-client-config <http://opendev.org/openstack/os-client-config>`_.
-See the functional tests instructions for information on setting up DevStack
-and os-client-config.

-Run
-***
-
-In order to run the entire examples test suite, simply run the
-``tox -e examples`` command inside of your source checkout. This will
-attempt to run every test command under ``/openstack/tests/examples/``
-in the source tree.::
