properties are for newstyle classes only (i. e. classes that inherit from
object).
from unittest import TestCase
import unittest
class Task(object):
def __init__(self,command):
self._command = command
def setNothing(self, value):
raise AttributeError
def getCommand(self):
return self._command
command=property(getCommand, setNothing)
# or just
# command=property(getCommand)
class taskTest(TestCase):
def testTask(self):
t = Task("dir c:")
c = t.command
self.assertEquals("dir c:", c)
def set():
t.command = "foo Bar"
self.assertRaises(AttributeError, set)
self.assertEquals("dir c:", t.command)
if __name__ == "__main__":
unittest.main()
