Do a functional doctest test on the app.
========================================

:Test-Layer: functional

Let's first create an instance of Trajectcave at the top level:

   >>> from trajectcave.app import TrajectCave
   >>> root = getRootFolder()
   >>> root['app'] = TrajectCave()


Run tests in the testbrowser
----------------------------

The zope.testbrowser.browser module exposes a Browser class that
simulates a web browser similar to Mozilla Firefox or IE.  We use that
to test how our application behaves in a browser.  For more
information, see http://pypi.python.org/pypi/zope.testbrowser.

Create a browser and visit the instance you just created:

   >>> from zope.testbrowser.testing import Browser
   >>> browser = Browser()
   >>> browser.open('http://localhost/app')

Check some basic information about the page you visit:

   >>> browser.url
   'http://localhost/app'
   >>> browser.headers.get('Status').upper()
   '200 OK'

Try to reach an instance of SomeForeignModel using the TrajectForSomeForeignModel Traject. THIS IS FAILING:
    
    >>< browser.open('http://localhost/app/foreigners/:funnyname')
    >>< browser.headers.get('Status').upper()
    '200 OK'


Perhaps because the url shouldn't include ':'?
THIS IS FAILING:


    >>< browser.open('http://localhost/app/foreigners/funnyname')
    >>< browser.headers.get('Status').upper()
    '200 OK'

Or perhaps simply because SomeForeignModel is not a view?
