# Guidelines for writing new hacking checks
|
|
#
|
|
# - Use only for Neutron specific tests. OpenStack general tests
|
|
# should be submitted to the common 'hacking' module.
|
|
# - Pick numbers in the range N3xx. Find the current test with
|
|
# the highest allocated number and then pick the next value.
|
|
# - Keep the test method code in the source file ordered based
|
|
# on the N3xx value.
|
|
# - List the new rule in the top level HACKING.rst file
|
|
# - Add test cases for each new rule to
|
|
# neutron/tests/unit/hacking/test_checks.py
