Excellent, that works! Thanks! I always forget about setattr. Here's full
sample code:
#! /usr/bin/env python
import unittest
class foo(object):
def getBar(self):
return 0
bar = property(getBar, None, None, "bar.")
class testFoo(unittest.TestCase):
def testSetter(self):
f = foo()
self.assertRaises(AttributeError, setattr, f, 'bar', 42)
if __name__=="__main__":
unittest.main()
// mark
