Passing mutable objects as default args is a known Python pitfall.
We'd better avoid this. This commit changes mutable default args with
None, then use 'arg = arg or {}', 'arg = arg or []'. For unit code which
doesn't use the args , just set with None. This commit also adds hacking
check.
This code was taken from commit 0bea84ac20fe498bd08f7212a0017196c8cb0812
in Nova.

Neutron Style Commandments
|
|
=======================
|
|
|
|
- Step 1: Read the OpenStack Style Commandments
|
|
http://docs.openstack.org/developer/hacking/
|
|
- Step 2: Read on
|
|
|
|
Neutron Specific Commandments
|
|
--------------------------
|
|
|
|
- [N319] Validate that debug level logs are not translated
|
|
- [N320] Validate that LOG messages, except debug ones, have translations
|
|
- [N321] Validate that jsonutils module is used instead of json
|
|
- [N322] Detect common errors with assert_called_once_with
|
|
- [N323] Enforce namespace-less imports for oslo libraries
|
|
- [N324] Prevent use of deprecated contextlib.nested.
|
|
- [N325] Python 3: Do not use xrange.
|
|
- [N326] Python 3: do not use basestring.
|
|
- [N327] Python 3: do not use dict.iteritems.
|
|
- [N328] Detect wrong usage with assertEqual
|
|
- [N329] Method's default argument shouldn't be mutable
|
|
|
|
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.
|
|
|
|
All unittest classes must ultimately inherit from testtools.TestCase. In the
|
|
Neutron test suite, this should be done by inheriting from
|
|
neutron.tests.base.BaseTestCase.
|
|
|
|
All setUp and tearDown methods must upcall using the super() method.
|
|
tearDown methods should be avoided and addCleanup calls should be preferred.
|
|
Never manually create tempfiles. Always use the tempfile fixtures from
|
|
the fixture library to ensure that they are cleaned up.
