|
38. 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.
