Venus Style Commandments ========================= - Step 1: Read the OpenStack Style Commandments http://docs.openstack.org/developer/hacking/ - Step 2: Read on Venus Specific Commandments ---------------------------- - [N314] Check for vi editor configuration in source files. - [N319] Validate that debug level logs are not translated. - [N322] Ensure default arguments are not mutable. - [N323] Add check for explicit import of _() to ensure proper translation. - [N328] LOG.info messages require translations `_LI()`. - [N329] LOG.exception and LOG.error messages require translations `_LE()`. - [N330] LOG.warning messages require translations `_LW()`. - [N333] Ensure that oslo namespaces are used for namespaced libraries. - [N336] Must use a dict comprehension instead of a dict constructor with a sequence of key-value pairs. - [C301] timeutils.utcnow() from oslo_utils should be used instead of datetime.now(). - [C303] Ensure that there are no 'print()' statements in code that is being committed. - [C304] Enforce no use of LOG.audit messages. LOG.info should be used instead. - [C305] Prevent use of deprecated contextlib.nested. - [C306] timeutils.strtime() must not be used (deprecated). - [C307] LOG.warn is deprecated. Enforce use of LOG.warning. - [C308] timeutils.isotime() must not be used (deprecated). - [C309] Unit tests should not perform logging. - [C310] Check for improper use of logging format arguments. General ------- - Use 'raise' instead of 'raise e' to preserve original traceback or exception being reraised:: except Exception as e: ... raise e # BAD except Exception: ... raise # OKAY 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. Venus is transitioning to use mock, rather than mox, and so new tests should use mock only. For more information on creating unit tests and utilizing the testing infrastructure in OpenStack Venus, please read the Venus testing `README.rst `_.
