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(), 'Z', 'QQ', '3', '€', u'€',
... '😴', '¥', '3²', 'ⅷ', '⑱', '᭓', b'\xc2\xb2'.decode('utf-8'))
>>> from stdnum.util import get_number_modules
Go over each module and try every value.
>>> for mod in get_number_modules():
... results = [ x for x in testvalues if mod.is_valid(x) != False ]
... if results:
... print(mod.__name__, results)
