For the purposes of creating an automated cross browser test, it would be good to have a fully functional PageTriage feature enabled in at least one test environment.
With proper permissions, on page http://test2.wikipedia.org/wiki/Special:NewPagesFeed, click to Review an article.
Resulting page has no "Curate this article" link under Toolbox, so curation toolbar may not be invoked at all.
On beta labs:
http://en.wikipedia.beta.wmflabs.org/wiki/Special:NewPagesFeed is missing graphics. Click through to reviewable page and review toolbar is missing graphics and messages. Also on beta there is no 'Curate this article' link, but curation toolbar appears automatically, which is not the case in production.
