JWebUnit to test File Upload

I am trying to test a File Upload field with JWebUnit but I do not know how to do that. I see that JWebUnit has a dependancy on common-fileupload so I expect that this is possible but I can see nothing documenting it so the feature may as well not exist. I have done some extensive searching and looking so I think soon I might even go as far as check ou开发者_JAVA百科t the JWebUnit code for traces but I'm still not sure how to get this done. How do I make sure that a file is added to the HTTP Post when the form submit button is clicked in the test? Thanks.

Okay, so as it turns out, after some searching through the source code I found a test on line 77 of a test file that basically explains how it works by doing it.
