You can also provide your own adapter and register it for your tests.
This example is extracted from zope.app.container unit tests :
from datetime import datetime
from zope.security import checker
from zope.dublincore.interfaces import IZopeDublinCore
from zope.app.testing import ztapi
class EntrySizeTestCase(unittest.TestCase):
def setUp(self):
class FauxDCAdapter(object):
implements(IZopeDublinCore)
__Security_checker__ = checker.Checker(
{"created": "zope.Public",
"modified": "zope.Public",
"title": "zope.Public",
},
{"title": "zope.app.dublincore.change"})
def __init__(self, context):
pass
title = 'faux title'
size = 1024
created = datetime(2001, 1, 1, 1, 1, 1)
modified = datetime(2002, 2, 2, 2, 2, 2)
ztapi.provideAdapter(IZODBWeblogEntry, IZopeDublinCore,
FauxDCAdapter)
Not tested anyway, but hope will help...
