Testing my tablebases

I would like to verify if my tablebases are valid. The best would be taking another tablebase, probing all positions and checking the result with my own tablebase.
Is there anyone who knows how to do that? Or maybe there is someone who has some code?

As well you can generate some stats and compare it to nalimov's *.tbs files

Or you can build your own verifier, that goes through all positions and test whether the value is fine by checking the values of the child-nodes.

Quoting kirill's great site about tablebases: http://kirill-kryukov.com/chess/tablebases-online/

to the right of all links you find a link to the tbs files
