How do you test apps with actual production data? What a given code is
being fed with in production, everywhere, using random
application&users specific data or inputs.

Obviously it is easy failed casts, but what do your tests cover? I do
not worry much about what we know but what we do not know. And
changing the casting rules opens a Pandora box.
