Hello,
I have thes setup and tearDown methods:
import unittest
import zope.testing.module
from zope.testing import doctest
from zope.component import testing, eventtesting
from zope.app.container.tests.placelesssetup import PlacelessSetup
from zope.app.testing import setup
container_setup = PlacelessSetup()
def blogSetUp(test):
zope.testing.module.setUp(test, 'Blog.doctest')
testing.setUp(test)
eventtesting.setUp(test)
container_setup.setUp()
setup.placelessSetUp()
setup.setUpTraversal()
def blogTearDown(test):
setup.placelessTearDown()
zope.testing.module.tearDown(test)
testing.tearDown(test)
and this is my README.txt containing the test:
>>> context = MyBlog
>>> from zope.publisher.browser import TestRequest
>>> from browser.views import RSSFeed
>>> request = TestRequest()
>>> view = RSSFeed(context, request)
>>> print view()
Since my code includes a call to absoluteURL I have added your setup and
tearDown methods. But there is still an error:
File "/home/florian/Zope3/src/zope/traversing/browser/absoluteurl.py",
line 34, in absoluteURL
return zope.component.getMultiAdapter((ob, request), IAbsoluteURL)()
File "/home/florian/Zope3/src/zope/traversing/browser/absoluteurl.py",
line 55, in __str__
raise TypeError(_insufficientContext)
TypeError: There isn't enough context to get URL information. This is
probably due to a bug in setting up location information.
Do you know what's missing here?
Thanks,
Florian
BTW: What would be the name of the MyViewClass if the page would be registered
without a class set?
