The tests were completely ad-hoc and did not use unittest or any other library. They had a hand-rolled runner which ran all the functions like test_one_one from a script.
The odd thing is that Python 2.7 + py.test + the functools.wraps version of the decorators worked OK. Could it be that I have inadvertently turned the logging module on and output from that is confusing the py.test runner?
