这个例子可能有帮助:

from webtest import TestApp
from nose.tools import eq_

class TestAuthentication(object):
    """
    Tests for the default authentication setup.

    If your application changes how the authentication layer is configured
    those tests should be updated accordingly
    """

    application_under_test = 'main'

    def setUp(self):
        """Method called by nose before running each test"""
        # Loading the application:
        conf_dir = config.here
        wsgiapp = loadapp('config:test.ini#%s' % self.application_under_test,
                          relative_to=conf_dir)
        self.app = TestApp(wsgiapp)
        # Setting it up:
        test_file = path.join(conf_dir, 'test.ini')
        cmd = SetupCommand('setup-app')
        cmd.run([test_file])

    def tearDown(self):
        """Method called by nose after running each test"""
        # Cleaning up the database:
        model.DBSession.remove()
        teardown_db()

    def test_forced_login(self):
        """Anonymous users are forced to login

        Test that anonymous users are automatically redirected to the login
        form when authorization is denied. Next, upon successful login they

        """
        # Requesting a protected area
        resp = self.app.get('/secc/', status=302)
        assert resp.location.startswith('http://localhost/login')
        # Getting the login form:
        resp = resp.follow(status=200)
        print resp.forms
        form = resp.forms
