What we do in FOP is calling GhostScript to convert the PDF to a bitmap which can then be either put side-to-side with a reference or visually "diffed" against a reference. This process isn't automated, yet.
See here: http://svn.apache.org/viewvc/xmlgraphics/fop/trunk/test/java/org/apache/fop/visual/ Of course, that doesn't test the non-visual features of PDF. But for that you can use any PDF library and some JUnit test cases.
