Testing¶

Run¶

In order to run the entire unit test suite, simply run the tox command inside of your source checkout. This will attempt to run every test command listed inside of tox.ini, which includes Python 2.7, 3.4, PyPy, and a PEP 8 check. You should run the full test suite on all versions before submitting changes for review in order to avoid unexpected failures in the continuous integration system.:

(sdk3)$ tox
...
py34: commands succeeded
py27: commands succeeded
pypy: commands succeeded
pep8: commands succeeded
congratulations :)

During development, it may be more convenient to run a subset of the tests to keep test time to a minimum. You can choose to run the tests only on one version. A step further is to run only the tests you are working on.:

(sdk3)$ tox -e py34                # Run run the tests on Python 3.4
(sdk3)$ tox -e py34 TestContainer  # Run only the TestContainer tests on 3.4

DevStack¶

There are many ways to run and configure DevStack. The link above will show you how to run DevStack a number of ways. You’ll need to choose a method you’re familiar with and can run in your environment. Wherever DevStack is running, we need to make sure that python-openstacksdk contributors are using the same configuration.

This is the local.conf file we use to configure DevStack.

[[local|localrc]]
# Configure passwords and the Swift Hash
MYSQL_PASSWORD=DEVSTACK_PASSWORD
RABBIT_PASSWORD=DEVSTACK_PASSWORD
SERVICE_TOKEN=DEVSTACK_PASSWORD
ADMIN_PASSWORD=DEVSTACK_PASSWORD
SERVICE_PASSWORD=DEVSTACK_PASSWORD
SWIFT_HASH=DEVSTACK_PASSWORD

# Configure the stable OpenStack branches used by DevStack
# For stable branches see

CEILOMETER_BRANCH=stable/OPENSTACK_VERSION

Replace DEVSTACK_PASSWORD with a password of your choice.

Replace OPENSTACK_VERSION with a stable branch of OpenStack (without the stable/ prefix on the branch name).

os-client-config¶

To connect the functional tests to an OpenStack cloud we use os-client-config. To setup os-client-config create a clouds.yaml file in the root of your source checkout.

This is an example of a minimal configuration for a clouds.yaml that connects the functional tests to a DevStack instance. Note that one cloud under clouds must be named test_cloud.

clouds:
  test_cloud:
    region_name: RegionOne
    auth:
      auth_url: http://xxx.xxx.xxx.xxx:5000/v2.0/
      username: demo
      password: secrete
      project_name: demo
    example:
      image_name: fedora-20.x86_64
      flavor_name: m1.small
      network_name: private
  rackspace:
    cloud: rackspace
    auth:
      username: joe
      password: joes-password
      project_name: 123123
    region_name: IAD

Replace xxx.xxx.xxx.xxx with the IP address or FQDN of your DevStack instance.

You can also create a ~/.config/openstack/clouds.yaml file for your DevStack cloud environment using the following commands. Replace DEVSTACK_SOURCE with your DevStack source checkout.:

(sdk3)$ source DEVSTACK_SOURCE/accrc/admin/admin
(sdk3)$ ./create_yaml.sh

Run¶

Functional tests are run against both Python 2 and 3. In order to run the entire functional test suite, run the tox -e functional and tox -e functional3 command inside of your source checkout. This will attempt to run every test command under /openstack/tests/functional/ in the source tree. You should run the full functional test suite before submitting changes for review in order to avoid unexpected failures in the continuous integration system.:

(sdk3)$ tox -e functional
...
functional: commands succeeded
congratulations :)
(sdk3)$ tox -e functional3
...
functional3: commands succeeded
congratulations :)

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.:

(sdk3)$ tox -e examples
...
examples: commands succeeded
congratulations :)
