Do a simple doctest test on the app.
************************************
:Test-Layer: functional

   >>> import grok
   >>> from zope.component import getMultiAdapter
   >>> from zope import schema
   >>> from pymenthon.forms.components import AddForm
   >>> from zope.interface import Interface
   >>> from zope.publisher.browser import TestRequest
   >>> class IPerson(Interface):
   ...    firstname = schema.TextLine(title=u'Firstname')
   ...    lastname = schema.TextLine(title=u'Lastname')
   ...
   >>> class People(grok.Application, grok.Container):
   ...    pass
   ...

Now we can create a JSON View

   >>> class PersonJSON(grok.JSON):
   ...    grok.context(People)
   ...
   ...    def hello(self):
   ...        return {'hi':'there'}
   ...

Finally, let's get the view

   >>> persons = People()
   >>> request = TestRequest()
   >>> form = getMultiAdapter((persons, request), name="hello")
