Castellan Style Commandments =============================================== - Step 1: Read the OpenStack Style Commandments http://docs.openstack.org/developer/hacking/ - Step 2: Read on Castellan Specific Commandments ------------------------------- N/A Creating Unit Tests ------------------- For every new feature, unit tests should be created that both test and (implicitly) document the usage of said feature. If submitting a patch for a bug that had no unit test, a new passing unit test should be added. If a submitted bug fix does have a unit test, be sure to add a new one that fails without the patch and passes with the patch. Running Tests ------------- The testing system is based on a combination of tox and testr. The canonical approach to running tests is to simply run the command ``tox``. This will create virtual environments, populate them with dependencies and run all of the tests that OpenStack CI systems run. Behind the scenes, tox is running ``testr run --parallel``, but is set up such that you can supply any additional testr arguments that are needed to tox. For example, you can run: ``tox -- --analyze-isolation`` to cause tox to tell testr to add --analyze-isolation to its argument list. Python packages may also have dependencies that are outside of tox's ability to install. Please refer to doc/source/devref/development.environment.rst for a list of those packages on Ubuntu, Fedora and Mac OS X. It is also possible to run the tests inside of a virtual environment you have created, or it is possible that you have all of the dependencies installed locally already. In this case, you can interact with the testr command directly. Running ``testr run`` will run the entire test suite. ``testr run --parallel`` will run it in parallel (this is the default incantation tox uses.)
