Guidelines for writing new hacking checks
|
|
|
|
- Use only for Nova 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 nova/tests/unit/test_hacking.py
