For example, zope.app.testing.setup.placelessSetUp() calls zope.app.container.tests.placelesssetup.PlacelessSetup().setUp() for you already, you don't need to do it twice. In fact the CleanUp().cleanUp(), which is the first thing that placelessSetUp() calls, undoes all the changfes made by container_setup.setUp(). The same applies to zope.component.testing.setUp.  http://en.wikipedia.org/wiki/Cargo_cult_programming I would suggest that you remove everything and keep just def blogSetUp(test): setup.placelessSetUp() setup.setUpTraversal() def blogTearDown(test): setup.placelessTearDown() > and this is my README.txt containing the test: > > >>> context = MyBlog You may want to actually create the object: >>> context = MyBlog() and sometimes it is a good idea to put it into the containment hierarchy, if you're going to look up things like absolute URLs: >>> from zope.app.folder import rootFolder >>> root = rootFolder() >>> root['my_blog'] = context > >>> 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.

When you use the <browser:page> directive, the ZCML maaagick creates a new class (with a funky name) at runtime, with extra attributes and methods. You cannot access that class from a unit test, because it doesn't exist in your source code. My suggestion is "don't do that". If you want a view with just a template, and you want to render it in a unit test, define a view class class MyTrivialViewClass(BrowserPage): __call__ = ViewPageTemplateFile('mytemplate.pt') HTH, Marius Gedminas -- You have moved the mouse. NT must be restarted for the changes to take effect.
