Here is the solution which I for now have to settle with. Mind that it is used
for testing only. Protect your eyes!
>>> from ZPublisher.tests.testBaseRequest import DummyResponse
>>> from ZPublisher.HTTPRequest import HTTPRequest
>>> from ZPublisher.HTTPResponse import HTTPResponse
>>> from Products.PloneTestCase import PloneTestCase
>>> import base64
>>> user_id = PloneTestCase.default_user
>>> password = PloneTestCase.default_password
>>> encoded = base64.encodestring( '%s:%s' % ( user_id, password ) )
>>> auth_header = 'basic %s' % encoded
>>> resp = DummyResponse()
... 'HTTP_AUTHORIZATION': auth_header,
... 'REQUEST_METHOD': 'GET',
... 'steps': ,
... '_hacked_path': 0,
... '_test_counter': 0,
... 'response' : resp
>>> request = HTTPRequest(stdin=None, environ=env, response=resp)
>>> request['PARENTS'] = [self.getPortal()]
Now the traversal up the context state view.
>>> contextState = request.traverse("weblog/issue193/"
The call to "request.traverse" differs from what TAL-traversal does. The
request URL has the view name '@@plone_context_state' appended. In my case I
had to remove that before the actual call.
>>> request['ACTUAL_URL'] = 'http://nohost/weblog/issue193'
