With py.test 0.9.1-3:
In [1]: from py.__.test.outcome import Outcome
In [2]: Outcome
Out[2]: <class py.__.test.outcome.Outcome at 0xb76f9b9c>
So they changed the interface and it breaks sympy. In
sympy/utilities/py.test we have:
try:
import py
disabled = False
except ImportError:
disabled = True
So normally it is disabled and not used if the py.test is not
installed. Thanks for noticing this, it is a bug and the fix is to
move all the imports into the "try" clause above.
