[pytest-dev] Automatically converting unittest asserts to py.test asserts.

[Cesar Canassa]

Abdelilah:

You have to create a wrapper script and call it from there, here is a
sample one:

from lib2to3.refactor import RefactoringTool
> import sys
>
> if __name__ == '__main__':
>     if len(sys.argv) < 2:
>         sys.exit('Usage: topytest.py [FILE ...]')
>     refactoring_tool = RefactoringTool(['fix_pytest'])
>     refactoring_tool.refactor(sys.argv[1:], write=True)


Holger:

Sure! I will start a repository for it.


Best,
Cesar Canassa
