However, to provide readable output for errors in even simple tests (like a == b) py.test does magic with stack frames and code objects - in order to discover the objects being compared. As this relies on what are essentially implementation details of the Python interpreter it means that some implementations (specifically IronPython which doesn't have Python stack frames and only a minimal representation of frame objects) will never be able to run it. I think it would be a bad idea to move *Python testing* itself over to a framework like this. I personally find unittest pretty readable, the feature most lacking is autodiscovery of tests which nose does seem to provide very well although I haven't used it yet.
