Our docs explicitly callout not to use externalization methods in Jest specs: docs.gitlab.com/ee/development/i18n/externalization.html#test-files-jest
I have drafted a merge request to ban the use outright gitlab.com/gitlab-org/gitlab/-/merge_requests/160707
However, we have quite a few of them which need to be removed before we can introduce the new rule.
This video described how to search the codebase (grep) to identify them and remove them.
If you would like to help us clean these up, please stop by #contribute on Discord: discord.gg/gitlab so we don't end up with merge conflicts from multiple contributors picking up the same violations- thanks!
