Testing using the Test Client
The test client is a class that can act like a simple
browser for testing purposes.
It allows the user to compose GET and POST requests, and
obtain the response that the server gave to those requests.
The server Response objects are annotated with the details
of the contexts and templates that were rendered during the
process of serving the request.
``Client`` objects are stateful - they will retain cookie (and
thus session) details for the lifetime of the ``Client`` instance.
This is not intended as a replacement for Twill, Selenium, or
other browser automation frameworks - it is here to allow
testing against the contexts and templates produced by a view,
rather than the HTML rendered to the end-user.
