@ -29,6 +29,7 @@ Neutron Specific Commandments
- [N340] Check usage of <module>.i18n (and neutron.i18n)
- [N341] Check usage of _ from python builtins
- [N342] String interpolation should be delayed at logging calls.
- [N343] Production code must not import from neutron.tests.*
- [N344] Python 3: Do not use filter(lambda obj: test(obj), data). Replace it
with [obj for obj in data if test(obj)].

@ -400,6 +400,15 @@ Where appropriate, exceptions can be added to the above script. If
code is not part of the Neutron namespace, for example, it's probably
reasonable to exclude their unit tests from the check.
.. note ::
At no time should the production code import anything from testing subtree
(neutron.tests). There are distributions that split out neutron.tests
modules in a separate package that is not installed by default, making any
code that relies on presence of the modules to fail. For example, RDO is one
of those distributions.
