Trying to demonstrate a bug where the WSGI environ gets polluted with Routes + Cherrypy

test_routes_dispatcher.py

import os
curdir = os.path.join(os.getcwd(), os.path.dirname(__file__))

import cherrypy

from cherrypy.test import helper


class RoutesDispatchTest(helper.CPWebCase):

    def setup_server():

        class Foo:
            def index(self):
                return "Hello from Foo"

        class Bar:

            def index(self):
                return "Hello from Bar"

        d = cherrypy.dispatch.RoutesDispatcher()
        d.mapper.explicit = False
        d.mapper.minimization = True
        d.connect('foo', '/server/foo', Foo())
        d.connect('bar', '/server/bar', Bar())
        d.connect('root_bar', '/', Bar())
        d.connect('root_meh', '/meh', Bar())

        conf = {'/': {'request.dispatch': d},
                'global': {'script_name': '/preview'}}
        cherrypy.tree.mount(None, '/preview', conf)
    setup_server = staticmethod(setup_server)

    def test_Routes_Dispatch(self):
        self.getPage("/preview/server/foo")
        self.assertStatus("200 OK")
        self.assertBody("Hello from Foo")

        self.getPage("/preview/server/bar")
        self.assertStatus("200 OK")
        self.assertBody("Hello from Bar")

        self.getPage("/preview/")
        self.assertStatus("200 OK")
        self.assertBody("Hello from Bar")

        self.getPage("/preview/meh")
        self.assertStatus("200 OK")
        self.assertBody("Hello from Bar")

        # uncomment below to get a 500 
        # because the lack of a trailing slash
        # makes environ['PATH_INFO'] be ''
        #self.getPage("/preview")
        #self.assertStatus("200 OK")
        #self.assertBody("Hello from Bar")
