[Grok-dev] ComponentLookupError: (<InterfaceClass zope.intid.interfaces.IIntIds>, '') on integration tests

[Noe Nieto]

I'm writing some integration test for our products. I'm placing that tests
in a separate package: homeviva.testing

When I run my test, with zope.testrunner, I'm always having the following
traceback:

Error in test test_consworks_views
(homeviva.testing.tests.test_dbmodels.ConsworksTestCase)

ComponentLookupError: (<InterfaceClass zope.intid.interfaces.IIntIds>, '')

My testcase looks like this:


class ConsworksTestCase(unittest.TestCase):
    """
    TestCase for the Consworks app object
    """
    layer = HomeVivaIntegrationLayer(homeviva.testing)

    def setUp(self):
        #Add test app
        from consworks.app import Consworks
        self.root = self.layer.getRootFolder()
        self.root['app'] = Consworks()
        self.app = self.root['app']

   def test_here(self):
       ....

I tried to manually  register a Intid utility in my layer, but with no
results.

from zope.app.wsgi.testlayer import BrowserLayer
from zope.site.hooks import getSiteManager
from zope.intid.interfaces import IIntIds
from zope.intid import IntIds

class HomeVivaIntegrationLayer(BrowserLayer):
    """
    Integration Layer for HomeViva.
    """

    def testSetUp(self):
        super(HomeVivaIntegrationLayer, self).testSetUp()
        # root = self.getRootFolder()
        # sm = getSiteManager()
        # sm.registerUtility(IntIds(), provided=IIntIds)
        # import pdb; pdb.set_trace( )



Anyone has hit this error? how did you fixed it?
