As a part of Wikimania, we had introduced a patch which allows one to add internationalized content while testing. However only few browser tests where written as a proof of concept. Now we can write more browser test and cover all the screenshots in the VisualEditor UserGuide.
@Vikassy: I am resetting the assignee of this task because there has not been progress lately (please correct me if I am wrong!).
Resetting the assignee avoids the impression that somebody is already working on this task. It also allows others to potentially work towards fixing this task.
Please claim this task again when you plan to work on it (via Add Action... → Assign / Claim in the dropdown menu) - it would be welcome! Thanks for your understanding!
