The patch adds a test to ensure that `getStats` returns the expected result after the page has been parsed, and cleans up the existing test a bit. Also, since I'm touching the file anyway, I'm making a small adjustment of the `getDownloadInfo` test. (I have no idea why I didn't just write it like this initially.)
