The comments application allows us to comment on pages from another
application. First we make an application::
>>> from testrunner import send_request
>>> from simpleapp import simple_app
Then we wrap the comment application around that::
>>> from comments import Comments
>>> wrapped_app = Comments(simple_app)
When we get pages from the application, we'll see the comment form at
the bottom::
>>> print send_request(wrapped_app, '/')
200 OK
Content-Type: text/html
Simple App
Simple App!
Now we can POST a request to that form::
>>> print send_request(wrapped_app, '/_comment/', method='POST',
... body={'path_info': '/', 'comment': 'hi'})
302 Found
Content-Type: ...
Location: /
...
We'll get back a redirect, which will lead us back to the original
page with our comment added::
>>> print send_request(wrapped_app, '/')
200 OK
Content-Type: text/html
...
