[py-dev] User defined exception - py.testing

[Santosh Philip]

I am having some trouble with testing user defined exceptions
==============
this one works
------------
def anexception(arg):
     """just raise an exception with ValueError"""
     if arg == 5:
         raise ValueError, 'Just a ValueError'

def test_anexception():
     """py.test for anexception"""
     import py.test
     py.test.raises(ValueError, anexception, 5)

===============
this one does not work
---------------
class MyError(Exception):
     """pass"""
     pass

def anotherexception(arg):
     """just raise an exception with ValueError"""
     if arg == 5:
         raise MyError, 'its a MyError'

def test_anotherexception():
     """py.test for anotherexception"""
     import py.test
     py.test.raises(ValueError, anotherexception, 5)
================

Are test for user defined exceptions working in py.test
or
Am I doing something wrong ?

when it doesn't work, the output looks like

MacBook:~/Documents/doe2python_DSU santosh$ py.test doesntwork.py
