Is the project interested in moving to use pytest conventions? This would mean something of the lines:

• Use assert instead of unittest assert methods
• Removing unittest classes
• Using fixtures for stdout/stderr capturing, temporary files, and more (and perhaps some internal ones too.)
• Using parameterized tests?

If so, I can help out here and there. As there are quite a lot of tests, it might make sense to this on a file by file basis or in pieces.

Thoughts?
