This file contains more detailed doctests for the stdnum.meid module. It
tries to test more corner cases and detailed functionality that is not
really useful as module documentation.
>>> from stdnum import meid
IMEI numbers without the software version (but optionally with a check
digit) should be valid numbers:
>>> meid.validate('49-015420-323751')
'49015420323751'
>>> meid.validate('35-209900-176148-1')
'35209900176148'
>>> meid.validate('35-209900-176148-2')
Traceback (most recent call last):
...
InvalidChecksum: ...
MEIDs can be represented as HEX strings (with and without check digit):
>>> meid.validate('AF 01 23 45 0A BC DE')
'AF0123450ABCDE'
>>> meid.validate('AF 01 23 45 0A BC DE C')
'AF0123450ABCDE'
>>> meid.validate('AF 01 23 45 0A BC DE D')
Traceback (most recent call last):
...
InvalidChecksum: ...
Also, MEIDs can be represented in decimal format (with and without check digit):
>>> meid.validate('29360 87365 0070 3710')
'AF0123450ABCDE'
>>> meid.validate('29360 87365 0070 3710 0')
'AF0123450ABCDE'
>>> meid.validate('29360 87365 0070 3710 1')
Traceback (most recent call last):
...
InvalidChecksum: ...
The validate() method should be fairly robust against invalid junk passed:
>>> meid.validate('29360 ABCDE 0070 3710')
Traceback (most recent call last):
...
InvalidFormat: ...
>>> meid.validate('GF 01 23 45 0A BC DE')
Traceback (most recent call last):
...
InvalidFormat: ...
Decimal format MEIDs with manufacturer code exceeding 32-bits should fail.
>>> meid.validate('99999 99999 0070 3710 4')
Traceback (most recent call last):
...
InvalidComponent: ...
Decimal format MEIDs with serial number exceeding 24-bits should fail.
>>> meid.validate('29360 87365 9999 9999 4')
Traceback (most recent call last):
...
InvalidComponent: ...
The compact method should convert to HEX if needed and can optionally leave
the check digit intact.
>>> meid.compact('49-015420-323751')
'49015420323751'
>>> meid.compact('35-209900-176148-2')
'35209900176148'
>>> meid.compact('35-209900-176148-2', strip_check_digit=False)
'352099001761482'
>>> meid.compact('af 01 23 45 0a bc de')
'AF0123450ABCDE'
>>> meid.compact('AF 01 23 45 0A BC DE C')
'AF0123450ABCDE'
>>> meid.compact('AF 01 23 45 0A BC DE C', strip_check_digit=False)
'AF0123450ABCDEC'
>>> meid.compact('29360 87365 0070 3710')
'AF0123450ABCDE'
>>> meid.compact('29360 87365 0070 3710 0')
'AF0123450ABCDE'
>>> meid.compact('29360 87365 0070 3710 0', strip_check_digit=False)
'AF0123450ABCDEC'
The format() function can add the check digit if needed. It should leave
alone existing check digits (even invalid ones).
>>> meid.format('35-209900-176148-2')
'35 20 99 00 17 61 48 2'
>>> meid.format('35-209900-176148')
'35 20 99 00 17 61 48'
>>> meid.format('35-209900-176148', add_check_digit=True)
'35 20 99 00 17 61 48 1'
>>> meid.format('af0123450abcDE')
'AF 01 23 45 0A BC DE'
>>> meid.format('af0123450abcDEC', add_check_digit=True)
'AF 01 23 45 0A BC DE C'
The format() function can also convert to decimal, recalculating the check
digit if needed (conversion will silently correct incorrect check digits):
>>> meid.format('35-209900-176148', format='dec')
'08913 28768 0153 2232'
>>> meid.format('35-209900-176148', format='dec', add_check_digit=True)
'08913 28768 0153 2232 3'
>>> meid.format('35-209900-176148-9', format='dec')
'08913 28768 0153 2232 3'
>>> meid.format('af0123450abcDE', format='dec')
'29360 87365 0070 3710'
>>> meid.format('af0123450abcDE', format='dec', add_check_digit=True)
'29360 87365 0070 3710 0'
>>> meid.format('af0123450abcDEC', format='dec')
'29360 87365 0070 3710 0'
>>> meid.format('293608736500703710', format='dec')
'29360 87365 0070 3710'
>>> meid.format('293608736500703710', format='dec', add_check_digit=True)
'29360 87365 0070 3710 0'
>>> meid.format('2936087365007037106', format='dec')
'29360 87365 0070 3710 6'
The format() function can also convert to hex, recalculating the check
digit if needed (conversion will silently correct incorrect check digits):
>>> meid.format('35-209900-176148', format='hex')
'35 20 99 00 17 61 48'
>>> meid.format('35-209900-176148', format='hex', add_check_digit=True)
'35 20 99 00 17 61 48 1'
>>> meid.format('35-209900-176148-9', format='hex')
'35 20 99 00 17 61 48 9'
>>> meid.format('af0123450abcDE', format='hex')
'AF 01 23 45 0A BC DE'
>>> meid.format('af0123450abcDE', format='hex', add_check_digit=True)
'AF 01 23 45 0A BC DE C'
>>> meid.format('af0123450abcDEF', format='hex')
'AF 01 23 45 0A BC DE F'
>>> meid.format('293608736500703710', format='hex')
'AF 01 23 45 0A BC DE'
>>> meid.format('293608736500703710', format='hex', add_check_digit=True)
'AF 01 23 45 0A BC DE C'
>>> meid.format('2936087365007037106', format='hex')
'AF 01 23 45 0A BC DE C'
The conversion function should work regardless of the check digit and
whether decimal or hex representation is used.
>>> meid.to_pseudo_esn('AF 01 23 45 0A BC DE C')
'8016B128'
>>> meid.to_pseudo_esn('29360 87365 0070 3710')
'8016B128'
