Yes.  You're not supposed to do that.  Views work with requests, not
content objects.

If you told us what you want to achieve, we could help you find a way to
do it that works with Zope 3 rather than against it.

Lately I've been using this pattern in my tests:

    #!/usr/bin/env python
    import unittest

    from zope.testing import doctest
    from zope.app.testing import setup
    from zope.app.folder import rootFolder
    from zope.traversing.api import getPath

    from mypackage import MyObject


    def doctest_something():
        """Bla bla bla

            >>> root = rootFolder()
            >>> root['my_object'] = my_object = MyObject()
            >>> getPath(my_object)
            '/my_object'

        """


    def setUp(test):
        setup.placelessSetUp()
        setup.setUpTraversal()


    def tearDown(test):
        setup.placelessTearDown()


    def test_suite():
        return doctest.DocTestSuite(setUp=setUp, tearDown=tearDown)


    if __name__ == '__main__':
        unittest.main(defaultTest='test_suite'))


I avoid setup.placefulSetUp, and I avoid zapi/ztapi.

Cheers,
