Development guidelines

Coding Guidelines

PEP8 checks should pass for all Blazar code. You may check it using the following command:

tox -e pep8

Also you should keep your code clear using more code style checks via pylint:

tox -e pylint

If you see any pep8/pylint errors in your code, it is mandatory to fix them before sending your change for review.

Testing Guidelines

Blazar repositories have unit tests that are run on all submitted code, and it is recommended for developers to execute them themselves to catch regressions early. Developers are also expected to keep the test suite up-to-date with any submitted code changes.

Unit tests might be run in TOX environments via the commands:

tox -e py36
tox -e py37

for Python 3.6 and Python 3.7 accordingly.

Note that the Blazar code base is not yet compatible with Python 3, so tests will be failing.

Note that some tests might use databases, the script tools/ sets up databases for the unit tests.

Documentation Guidelines

Currently Blazar docs are partially written on OpenStack wiki pages, and partially using Sphinx / RST located in the main repo in doc directory.

To build Sphinx / RST docs locally run the following command:

tox -e docs

Then you can access generated docs in the doc/build/ directory, for example, the main page would be doc/build/html/index.html.
