It appears that the nose compatibility is not good enough that you can
just assume your nose tests will work in py.test. When I look at it
closely, it looks more like marketing than actual working software. A
lot of the compatibility mode depends on the similarity between the
systems, but there are some things where there is actual compatibility code.
I know of nothing you can do in nose that you can't do in py.test.
There are many differences in syntax, though.
It is still possible to write to a simplified test format that work in
both systems. I have sample tests that work in both unmodified that
have: module setup, module teardown, test function, test class (with
setup and teardown), skip test function/method (using a helper
function), test generator using yield
