Development Guidelines¶

Coding Guidelines¶

For all the code in Murano we have a rule - it should pass PEP 8.

To check your code against PEP 8 run:

tox -e pep8

Blueprints and Specs¶

Murano team uses the murano-specs repository for its blueprint and specification (specs) review process. See Launchpad to propose or see the status of a current blueprint.

Testing Guidelines¶

Murano has a suite of tests that are run on all submitted code, and it is recommended that developers execute the tests themselves to catch regressions early. Developers are also expected to keep the test suite up-to-date with any submitted code changes.

Unit tests are located at murano/tests.

Murano’s suite of unit tests can be executed in an isolated environment with Tox. To execute the unit tests run the following from the root of Murano repo on Python 2.7:

tox -e py27

Documentation Guidelines¶

Murano dev-docs are written using Sphinx / RST and located in the main repo in doc directory.

The documentation in docstrings should follow the PEP 257 conventions (as mentioned in the PEP 8 guidelines).

More specifically:

1. Triple quotes should be used for all docstrings.
2. If the docstring is simple and fits on one line, then just use one line.
3. For docstrings that take multiple lines, there should be a newline after the opening quotes, and before the closing quotes.
4. Sphinx is used to build documentation, so use the restructured text markup to designate parameters, return values, etc. Documentation on the sphinx specific markup can be found here:

Run the following command to build docs locally.

tox -e docs
