testing language-independent content
====================================

This file is not yet finished. We need to register an Archetype with
LanguageIndependent fields and test against that... (look at
doctest_behavior.txt in plone.multilingualbehavior).

::
    >>> from plone.app.testing import ( 
    ...     TEST_USER_ID, 
    ...     TEST_USER_NAME, 
    ...     TEST_USER_PASSWORD,
    ...     login,
    ...     setRoles
    ... )

    >>> from plone.testing.z2 import Browser

    >>> browser = Browser(layer['app'])
    >>> browser.handleErrors = False
    >>> portal = layer['portal']

    >>> browser.addHeader('Authorization', 'Basic %s:%s' %(TEST_USER_NAME, TEST_USER_PASSWORD))
    >>> setRoles(portal, TEST_USER_ID, ['Manager'])
    >>> login(portal, TEST_USER_NAME)

create an Archetypes object::
        
    >>> content_id = portal.invokeFactory(type_name='Document', id="samplecontent")
    >>> portal[content_id].setTitle("Sample Content")

We should be able to access the object, it should provide the marker
interface ``plone.app.multilingual.interfaces.ITranslatable`` and 
``archetypes.multilingual.interfaces.IArchetypesTranslatable``::

    >>> obj = portal.get(content_id)
    >>> from plone.app.multilingual.interfaces import ITranslatable
    >>> ITranslatable.providedBy(obj)
    True

    >>> from archetypes.multilingual.interfaces import IArchetypesTranslatable
    >>> IArchetypesTranslatable.providedBy(obj)
    True

We should also be able to access the adapter for ``plone.app.multilingual.interfaces.ILanguage``::

    >>> from Products.CMFPlone.interfaces import ILanguage
    >>> from zope.component import queryAdapter
    >>> adapter = queryAdapter(obj, ILanguage)
    >>> adapter == None
    False

set the language ::
    
    >>> adapter.set_language('af')

get the language::

    >>> adapter.get_language()
    'af'

Translate the object::

    >>> from plone.app.multilingual.interfaces import ITranslationManager
    >>> manager = ITranslationManager(portal[content_id])

Manually call update on the manager, to ensure that the TG is up to date.
Note: This should happen via event subscriber outside of tests.

    >>> manager.update()
    >>> manager.add_translation('en')
    >>> obj_en = manager.get_translation('en')
    >>> import transaction; transaction.commit()
