[Zope] Offline testing

[Chris McDonough]

Hi John...

This might have to do with the fact that PythonScripts are looking for
REQUEST.  When you do "import Zope; app=Zope.app()", a REQUEST cannot be
acquired through objects in the system.  In normal operation, they can be.
Here's a way around it:

import ZODB # this is "magical", unfortunately
import os
from os import environ
from sys import stdin
from ZPublisher.HTTPRequest import HTTPRequest
from ZPublisher.HTTPResponse import HTTPResponse
from ZPublisher.BaseRequest import RequestContainer

def makerequest(app):
    resp = HTTPResponse()
    environ['SERVER_NAME']='foo'
    environ['SERVER_PORT']='80'
    environ['REQUEST_METHOD'] = 'GET'
    req = HTTPRequest(stdin, environ, resp)
    return app.__of__(RequestContainer(REQUEST = req))

class ATest(TestCase):
    def setUp(self):
        import Zope
        self.app = makerequest(Zope.app())

self.app will be bound to a Zope instance with a fake request in all your
test cases now.
