Testing of the web projects is very hard. We try to cover all application with unit tests and twill tests. And if we have a lot of javascript, we also make selenium tests.

To use twill tests from the nosetests and Django, we’ve created simple helper to create many tests faster. Here is it:

 # -*- coding: utf-8 -*-
 IP = '127.0.0.1'
 PORT = 8088
 SITE = 'http://%s:%s' % (IP, PORT)

 class TwillMock(object):

    def setup(self):
        '''
        — setup twill virtual web server
        '''
        from django.core.servers.basehttp import AdminMediaHandler
        from django.core.handlers.wsgi import WSGIHandler

        app = AdminMediaHandler(WSGIHandler())
        add_wsgi_intercept(IP, PORT, lambda: app)

Making new test class derived from the TwillMock class make creation of nose twill tests much easier.
Look at the example of such test:

class TestLogin(TwillMock):

    def test_start_page(self):
        """
        Test start_page view
        """
        go(SITE)
        code(200)
        check_links()

    def test_login(self):
        go(SITE + '/accounts/login/')
        code(200)
        show()
        formvalue(1, 'username',  'test1')
        formvalue(1, 'password', 'test1')
        submit()
        code(200)
