Some basic tests for valid numbers.

>>> handelsregisternummer.validate('Bad Homburg v.d.H. PR 11223')
'Bad Homburg v.d.H. PR 11223'
>>> handelsregisternummer.validate('Ludwigshafen a.Rhein (Ludwigshafen) VR 11223')
'Ludwigshafen a.Rhein (Ludwigshafen) VR 11223'
>>> handelsregisternummer.validate('Aachen HRA 11223', company_form='KG')
'Aachen HRA 11223'
>>> handelsregisternummer.validate('Frankfurt/Oder GnR 11223', company_form='e.G.')
'Frankfurt/Oder GnR 11223'
>>> handelsregisternummer.validate('Bad Homburg v.d.H. PR 11223', company_form='PartG')
'Bad Homburg v.d.H. PR 11223'
>>> handelsregisternummer.validate('Ludwigshafen a.Rhein (Ludwigshafen) VR 11223', company_form='e.V.')
'Ludwigshafen a.Rhein (Ludwigshafen) VR 11223'
>>> handelsregisternummer.validate('Berlin (Charlottenburg) HRA 11223 B')
'Berlin (Charlottenburg) HRA 11223 B'
>>> handelsregisternummer.validate('Berlin (Charlottenburg) HRB 11223B')
'Berlin (Charlottenburg) HRB 11223 B'
>>> handelsregisternummer.validate('Berlin (Charlottenburg) HRA 11223 B')
'Berlin (Charlottenburg) HRA 11223 B'
>>> handelsregisternummer.validate('Berlin (Charlottenburg) HRB 11223B')
'Berlin (Charlottenburg) HRB 11223 B'


Tests for some corner cases.

>>> handelsregisternummer.validate('Berlin (Charlottenburg) HRA 11223 BBBB')
Traceback (most recent call last):
  ...
InvalidFormat: ...


The court name can also be shortened and various encodings are accepted but
we only return either Unicode or UTF-8 (Python 2 only). The tests are a bit
funky so they work both in Python 2 and Python 3.

>>> handelsregisternummer.validate('Berlin HRB 11223 B')  # Charlottenburg missing
'Berlin (Charlottenburg) HRB 11223 B'
>>> handelsregisternummer.validate('St. Ingbert HRA 61755')
'St. Ingbert (St Ingbert) HRA 61755'
>>> number = u'K\xf6ln HRB 49263'  # Unicode
>>> handelsregisternummer.validate(number) == number
True
>>> utf8 = 'K\xc3\xb6ln HRB 49263'  # UTF-8
>>> handelsregisternummer.validate(utf8) == 'Köln HRB 49263'
True
>>> iso885915 = 'K\xf6ln HRB 49263'  # ISO-8859-15
>>> handelsregisternummer.validate(iso885915) == 'Köln HRB 49263'
True
>>> ascii = 'Koln HRB 49263'  # ASCII replaced
>>> handelsregisternummer.validate(ascii) == 'Köln HRB 49263'
True
>>> handelsregisternummer.validate('KXln HRB 49263')  # too wrong
Traceback (most recent call last):
  ...
InvalidComponent: ...
>>> handelsregisternummer.validate('Hamburg HRA 61755')
'Hamburg HRA 61755'
>>> handelsregisternummer.validate('Homburg HRA 61755')
'Homburg HRA 61755'


The compact function does minimal validation.
>>> handelsregisternummer.compact('KXln HRB 49263')
'KXln HRB 49263'


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