XSLT Testing

I found this on the XSL mailling list: http://assets.expectnation.com/15/event/2/Testing%20XSLT%20Presentation.pdf

The document as such is great, but now I wonder which approach is the best for me respectively is the eaisest to learn.

At the moment, I look at I http://utf-x.sourceforge.net/manual/manual.pdf, but I am really not sure this is the way to go. One question seems to be with or without Java.
