Hi, I m trying to make my first content type with zope3. The code is available there: http://github.com/toutpt/z3weblog.entry/tree
I m following the second edition of the book "web component developement with zope3", i know this is not the last edition. So, i m making a ISized component for my simple content type, with a simple unittest, but now, i want to use zope.dublincore package and i get an error when i m launch the tests:

============
The trace back is very clear, the zope.dublincore components are not loaded. The question is : what is the best way to load components in unittests ? Do just i have to load the zcml of zope.dublincore, or do i have to register only needed components, if so how can i do that ?
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...
