can you confirm you want something like:

class MyObject(object):
   @property
   def myProperty(self):
       raise Exception()

...
myObject = MyObject()
self.assertRaises(Exception, getattr, myObject, 'myProperty')

?

f.e:
>>> getattr(myObject, 'myProperty')
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "<stdin>", line 4, in myProperty
Exception

Else I can't get it to work.
