practice, this means that the tests should initially be run against a stable

|

~~~~~~~~~~~~~
|
||||
|
||||
To connect the functional tests to an OpenStack cloud we use
|
||||
`os-client-config <http://opendev.org/openstack/os-client-config>`_.
|
||||
To setup os-client-config create a ``clouds.yaml`` file in the root of your
|
||||
source checkout.
|
||||
To connect the functional tests to an OpenStack cloud we require a
|
||||
``clouds.yaml`` file, as discussed in :doc:`/user/config/configuration`.
|
||||
You can place this ``clouds.yaml`` file in the root of your source checkout or
|
||||
in one of the other standard locations, ``$HOME/.config/openstack`` or
|
||||
``/etc/openstack``.
|
||||
|
||||
There must be at least three clouds configured, or rather three accounts
|
||||
configured for the one cloud. These accounts are:
|
||||
|
||||
- An admin account, which defaults to ``devstack-admin`` but is configurable
|
||||
via the ``OPENSTACKSDK_OPERATOR_CLOUD`` environment variable,
|
||||
- A user account, which defaults to ``devstack`` but is configurable
|
||||
via the ``OPENSTACKSDK_DEMO_CLOUD`` environment variable, and
|
||||
- An alternate user account, which defaults to ``devstack-demo`` but is
|
||||
configurable via the ``OPENSTACKSDK_DEMO_CLOUD_ALT`` environment variable
|
||||
|
||||
In addition, you must indicate the names of the flavor and image that should be
|
||||
used for tests. These can be configured via ``functional.flavor_name`` and
|
||||
``functional.image_name`` settings in the ``clouds.yaml`` file.
|
||||
|
||||
Finally, you can configure the timeout for tests using the
|
||||
``OPENSTACKSDK_FUNC_TEST_TIMEOUT`` environment variable (defaults to 300
|
||||
seconds). Some test modules take specific timeout values. For example, all
|
||||
tests in ``openstack.tests.functional.compute`` will check for the
|
||||
``OPENSTACKSDK_FUNC_TEST_TIMEOUT_COMPUTE`` environment variable before checking
|
||||
for ``OPENSTACKSDK_FUNC_TEST_TIMEOUT``.
|
||||
|
||||
.. note::
|
||||
|
||||
Recent versions of DevStack will configure a suitable ``clouds.yaml`` file
|
||||
for you, which will be placed at ``/etc/openstack/clouds.yaml``.
|
||||
|
||||
This is an example of a minimal configuration for a ``clouds.yaml`` that
