Tempest

Tempest is the OpenStack Integration test suite. It is installed by default and is used to provide integration testing for many of the OpenStack services. Just like DevStack itself, it is possible to extend Tempest with plugins. In fact, many Tempest plugin packages also include DevStack plugin to do things like pre-create required static resources.

The Tempest documentation provides a thorough guide to using Tempest. However, if you simply wish to run the standard set of Tempest tests against an existing deployment, you can do the following:

cd /opt/stack/tempest
/opt/stack/data/venv/bin/tempest run ...

The above assumes you have installed DevStack in the default location (configured via the DEST configuration variable) and have enabled virtualenv-based installation in the standard location (configured via the USE_VENV and VENV_DEST configuration variables, respectively).
