Hi Dan,
the test fails at checking the prerequisites. It tries to load the image page and looks
for a specific div element which is not present if the image was not uploaded correctly
(id=filetoc). This might have changed across the versions of MediaWiki.
Did you install the PagedTiffHandler extension? It depends on ImageMagick, so it might
have rejected the upload. Although then it should have produced an error message ;) So the
other question is, which MediaWiki version do you run the tests on?
Regards,
Markus
