[Zope3-Users] Persistent subclasses in tests

2006-07-23 Thread Darryl Cousins 
Hi,

I've have a problem with the following and I hope someone can shed some
light for me, I can't figure out what I am missing::

 from ZODB.tests.util import DB
 import transaction
 db = DB()
 conn = db.open()
 root = conn.root()

 from persistent import Persistent
 p = Persistent()
 root['p'] = p

Thats fine, but::

 class TestItem(Persistent):
... pass

 item = TestItem()
 root['item'] = item

 transaction.commit()
Traceback (most recent call last):

Yup, you need to handle a case like that specially.

See zope.testing.module

Hi Gary,

Thanks for that. For those who follow

tests.py::

  import unittest

  from zope.testing import doctest
  from zope.testing import module

  name = 'tfws.cart.README'

  def setUp(test):
  module.setUp(test, name)

  def tearDown(test):
  module.tearDown(test, name)

  def test_suite():
  return unittest.TestSuite((
doctest.DocFileSuite('README.txt',
setUp=setUp, tearDown=tearDown,
optionflags=doctest.ELLIPSIS
),
))

if __name__ == '__main__':
unittest.main(defaultTest='test_suite')
