Overview

Purpose

This class delegates to the uploaded Tempfile, and adds content type and original filename attributes.

If you are testing a multipart/form, use this class to pretend you uploaded a file:

"uploaded_file" => Upload.new(anIO,
                              "image/png",
                              "my_favorite_image.png" )

See Web::Testing for more information.
