[NTG-context] ConTeXt unit testing

Hi! Are there any automatic unit test for ConTeXt distribution? At least the bug with referenceformat can be catched using something like context test pdftotext test.pdf test.txt diff test.txt test.txt-good And the bug with broken footnote can be catched using just "context test". If there are unit test, where can I find them (I'd like to add more)? If there are no, any objections against adding them, and testing before releasing new beta?
