@rajcze @jbergstroem PTAL I had to reapply py3 compat, and the builtin tests are failing:

% python3 tap2junit/tap13.py
ok 1 - Input file opened # None None
None
None
not ok 2 - First line of the input valid # None None
['---',
 "        message: 'First line invalid'",
 '        severity: fail',
 '        data:',
 "          got: 'Flirble'",
 "          expect: 'Fnible'",
 '...']
{'data': {'expect': 'Fnible', 'got': 'Flirble'},
 'message': 'First line invalid',
 'severity': 'fail'}
ok 3 - Read the rest of the file # None None

 '            - 3',
 '            - 2',
 '        expect:',
 '            - 1',
 '            - 2',
 '            - 3',
 '...']
{'data': None,
 'expect': [1, 2, 3],
 'got': [1, 3, 2],
 'message': 'Failure message',
 'severity': 'fail'}
% echo $?
0

Its odd that exit code is 0 on success.

@jbergstroem any thoughts? the new version has a license that doesn't cause any IP issues, do you think its functional?

Happy to merge it. I haven't had the time to look at the failing tests though..

@cclauss do you have any interest in figuring out how to make the updated tap13 work/pass tests?
