 "Use ddt.named_data decorator to avoid random test names"

merged 5 days ago

[Soniya Murlidhar Vyas (svyas)]

IMHO, this failure is caused because of following reasons:-

1. This patch[1] uses '.' instead of '_' which caused ddt module to throw error as follows:-
---
@ddt.named_data(\nAttributeError: module 'ddt' has no attribute 'named_data'\n
---

2. There is an solution available for this issue[2] which is still not merged which is why manila_tempest_tests are failing

[Victoria Martinez de la Cruz (vkmc)]

ddt named_data has been included since ddt >= 1.5.0 [0][1]

the version of ddt has been pushed in manila-tempest-tests to 1.6.0 [2]

the version of ddt shipped in centos9 is 1.4.4

we need to bump the version of ddt in centos9 in order to fix this issue or revert the change that introduced the usage of this decorator
