This file contains some tests for modules in the stdnum package to
check whether all provided is_valid() functions can handle clearly
invalid junk.

>>> testvalues = ( None, '*&^%$', '', 0, False, object(), 'Q', 'QQ', '3')

Go over each imported module and try every value.

>>> for mod in locals().values():
...     if hasattr(mod, 'is_valid'):
...         results = [ x for x in testvalues if mod.is_valid(x) ]
...         if results:
...             print mod.__name__, results
