Hi all, as described in this e-mail thread http://lists.idyll.org/pipermail/testing-in-python/2012-April/004898.html , tox is currently lacking an easy option to run 2to3 over a test suite that is not part of the package.
Holger suggested adding specific options to tox.ini, but maybe a documentation fix is sufficient. IOW, is there a good (cross-platform) way, to specify these steps in tox.ini:
cp test <tmpdir>/test # note cp is spelled copy on windows! 2to3 <tmpdir>/test py.test <tmpdir>/test
