This file contains more detailed doctests for the stdnum.iso7064 package. It
tries to test more corner cases and detailed functionality that is not
really useful as module documentation.
>>> from stdnum.iso7064 import mod_11_10, mod_11_2, mod_37_2, mod_37_36, mod_97_10
These are normal variations of Mod 11, 10 that should just work.
>>> mod_11_10.is_valid('12323')
True
>>> mod_11_10.is_valid('546794')
True
>>> mod_11_10.calc_check_digit('0794')
'5'
>>> mod_11_10.is_valid('07945')
True
>>> mod_11_10.calc_check_digit('00200667308')
'5'
>>> mod_11_10.is_valid('002006673085')
True
>>> mod_11_10.is_valid('002006673084')
False
>>> mod_11_10.calc_check_digit('00200667309')
'3'
>>> mod_11_10.calc_check_digit('00200667310')
'8'
>>> mod_11_10.calc_check_digit('00200667311')
'6'
>>> mod_11_10.calc_check_digit('00200667312')
'4'
These normal tests of Mod 11, 2 should just work.
>>> mod_11_2.calc_check_digit('0794')
'0'
>>> mod_11_2.is_valid('07940')
True
>>> mod_11_2.calc_check_digit('079')
'X'
>>> mod_11_2.is_valid('079')
True
These normal tests of Mod 37, 2 should just work
>>> mod_37_2.calc_check_digit('G123498654321')
'H'
Furthermore the is_valid() method should be fairly robust against invalid
junk passed:
>>> testvalues = ( None, '*&^%$', False, object() )
>>> [ x for x in testvalues if mod_11_10.is_valid(x) ]
[]
>>> [ x for x in testvalues if mod_11_2.is_valid(x) ]
[]
>>> [ x for x in testvalues if mod_37_2.is_valid(x) ]
[]
>>> [ x for x in testvalues if mod_37_36.is_valid(x) ]
[]
>>> [ x for x in testvalues if mod_97_10.is_valid(x) ]
[]
