    In order to be able to traverse to the PageTemplate view, we need
    a traversable object:

      >>> from Products.Five.tests.testing import manage_addFiveTraversableFolder
      >>> manage_addFiveTraversableFolder(self.folder, 'testoid', 'Testoid')

    We tell Zope to translate the messages by passing the
    ``Accept-Language`` header which is processed by the
    ``IUserPreferredLangauges`` adapter:

      >>> print http(r'''
      ... GET /test_folder_1_/testoid/@@i18n.html HTTP/1.1
      ... Accept-Language: de
      ... ''')
      HTTP/1.1 200 OK
