I would think that non random would be in alphabetical order of test_case_name (we are doing auto registration) but that's not what we're seeing. Non-random seems to indicate maybe some kind of static initialization order, which is random.

You are correct that the order is effectively the static initialization 
order.
This is not completely random.  Test cases in the same translation unit
should be executed in order.
