list all suburls and check if broken in python

Here is an improved class based on excellent @sneawo answer. Features include:

• automatic loading of all urlconfs based on settings.ROOT_URLCONF;
• recursive loading of included urlconfs;
• testing url patterns that expect keyword parameters (via default parameters);
• testing for different http codes;
• testing urls that work only for logged in users.

Improvements are welcome.

            Test all pattern in root urlconf and included ones.
            Do GET requests only.
            A pattern is skipped if any of the conditions applies:
                - pattern has no name in urlconf
                - pattern expects any positinal parameters
                - pattern expects keyword parameters that are not specified in @default_kwargs
            If response code is not in @allowed_http_codes, fail the test.
            if @credentials dict is specified (e.g. username and password),
                login before run tests.
            If @logout_url is specified, then check if we accidentally logged out
                the client while testing, and login again
            Specify @default_kwargs to be used for patterns that expect keyword parameters,
                e.g. if you specify default_kwargs={'username': 'testuser'}, then
                for pattern url(r'^accounts/(?P<username>[\.\w-]+)/$' 
                the url /accounts/testuser/ will be tested.
            If @quiet=False, print all the urls checked. If status code of the response is not 200,
                print the status code.

Use show-urls command in django-extensions as a starting point. (documentation)

python manage.py show_urls
