How can I unit test responses from the webapp WSGI application in Google App Engine?

Question

I\'d like to unit test responses from the Google App Engine webapp.WSGIApplication, for example request the url \'/\' and test that the responses status code is 200, using G

I have added a sample application to the GAEUnit project which demonstrates how to write and execute a web test using GAEUnit. The sample includes a slightly modified version of the 'webtest' module ('import webbrowser' is commented out, as recommended by David Coffin).

Here's the 'web_tests.py' file from the sample application 'test' directory:

import unittest
from webtest import TestApp
from google.appengine.ext import webapp
import index

class IndexTest(unittest.TestCase):

  def setUp(self):
    self.application = webapp.WSGIApplication([('/', index.IndexHandler)], debug=True)

  def test_default_page(self):
    app = TestApp(self.application)
    response = app.get('/')
    self.assertEqual('200 OK', response.status)
    self.assertTrue('Hello, World!' in response)

  def test_page_with_param(self):
    app = TestApp(self.application)
    response = app.get('/?name=Bob')
    self.assertEqual('200 OK', response.status)
    self.assertTrue('Hello, Bob!' in response)

Actually WebTest does work within the sandbox, as long as you comment out

import webbrowser

in webtest/__init__.py
