Testing

Python Guideline Enforcement

All code has to pass the pep8 style guideline to merge into OpenStack, to validate the code against these guidelines you can run:

$ tox -e pep8

Unit Testing

It is strongly encouraged to run the unit tests locally under one or more test environments prior to submitting a patch. To run all the recommended environments sequentially and pep8 style guideline run:

$ tox

You can also selectively pick specific test environments by listing your chosen environments after a -e flag:

$ tox -e py36,py38,pep8

Note

Tox sets up virtual environment and installs all necessary dependencies. Sharing the environment with devstack testing is not recommended due to conflicting configuration with system dependencies.
