This file contains more detailed doctests for the stdnum.nz.bankaccount
module. It tries to cover more corner cases and detailed functionality that
is not really useful as module documentation.

>>> from stdnum.nz import bankaccount


Algorithm examples taken from
https://www.ird.govt.nz/software-providers/explore-products-contents/reporting/withholding-taxes/rwt-and-nrwt-certificate-filing-options.html#02

>>> bankaccount.validate('01-902-0068389-00')  # algorithm A
'0109020068389000'
>>> bankaccount.validate('08-6523-1954512-001')  # algorithm D
'0865231954512001'

There does not seem to be a current bank with the 26 bank code, so we
only validate the check digit algorithm here:

>>> def checksum_is_valid(number):
...     return bankaccount._calc_checksum(bankaccount.compact(number)) == 0
>>> checksum_is_valid('26-2600-0320871-032')  # algorithm G
True


These are constructed numbers that test some corner cases. No actual numbers
were found to cover these tests:

>>> bankaccount.validate('01-902-0998384-00')  # algorithm B, high account nr
'0109020998384000'
>>> checksum_is_valid('09-0-37331-00')  # algorithm E, unknown bank
True
>>> checksum_is_valid('25-2545-3153624-00')  # algorithm F, unknown bank
True


These have been found online and should all be valid numbers.
