======================
 plone.app.discussion
======================

This is a functional test for the plone.app.discussion comments viewlet. 

We use zope.testbrowser to simulate browser interaction in order to show how
the plone.app.discussion commenting works.


Setting up and logging in
-------------------------

First we have to set up some things and login.

    >>> app = layer['app']
    >>> from plone.testing.z2 import Browser
    >>> browser = Browser(app)
    >>> browser.handleErrors = False
    >>> browser.addHeader('Authorization', 'Basic admin:secret')
    >>> portal = layer['portal']    
    >>> portal_url = 'http://nohost/plone'

By default, only HTTP error codes (e.g. 500 Server Side Error) are shown when an 
error occurs on the server. To see more details, set handleErrors to False:

    >>> browser.handleErrors = False

We also keep another testbrowser handy for testing how tiles are rendered if
you're not logged in::

    >>> unprivileged_browser = Browser(app)

Make sure we have a test user from the layer and it uses fancy characters:

    >>> from Products.CMFCore.utils import getToolByName
    >>> mtool = getToolByName(portal, 'portal_membership', None)
    >>> mtool.getMemberById('jim').getProperty('fullname')
    'Jim Fult\xc3\xb8rn'

Create a public page with comments allowed.

    >>> browser.open(portal_url)
    >>> browser.getLink(id='document').click()
    >>> browser.getControl(name='title').value = "Doc1"
    >>> browser.getControl(name='allowDiscussion:boolean').value = True
    >>> browser.getControl(name='form.button.save').click()
    >>> urldoc1 = browser.url
          
Check that the form has been properly submitted

    >>> browser.url
    'http://nohost/plone/doc1'


Comment Viewlet
---------------
        
Check that the old comments viewlet does not show up
    
    >>> 'discussion_reply_form' in browser.contents
    False
        
Check that the comment form/viewlet shows up

    >>> 'formfield-form-widgets-in_reply_to' in browser.contents
    True
    
    >>> 'formfield-form-widgets-text' in browser.contents
    True


Post a comment as admin
-----------------------

Login as admin.

    >>> from plone.app.testing import setRoles
    >>> from plone.app.testing import TEST_USER_NAME
    >>> setRoles(portal, TEST_USER_NAME, ['Manager'])

Post a comment as admin.

    >>> browser.getControl(name='form.widgets.text').value = "Comment from admin" 
    >>> submit = browser.getControl(name='form.buttons.comment')
    >>> submit.click() 

Check if comment has been added properly.
    
    >>> '<a href="http://nohost/plone/author/admin">admin</a>' in browser.contents
    True
    
    >>> browser.contents
    '...<a href="http://nohost/plone/author/admin">admin</a>...says:...'
     
    >>> "Comment from admin" in browser.contents
    True
    

Post a comment as user
----------------------

Login as user 'jim'. 

    >>> browser.open(portal_url + '/logout')
    >>> browser.open(portal_url + '/login_form')
    >>> browser.getControl(name='__ac_name').value = 'jim'
    >>> browser.getControl(name='__ac_password').value = 'secret'
    >>> browser.getControl(name='submit').click()

Post a comment as user jim.

    >>> browser.open(urldoc1)
    >>> browser.getControl(name='form.widgets.text').value = "Comment from Jim" 
    >>> submit = browser.getControl(name='form.buttons.comment')
    >>> submit.click() 

Check if the comment has been added properly.

    >>> browser.contents
    '...<a href="http://nohost/plone/author/jim">Jim Fult\xc3\xb8rn</a>...says:...'

    >>> "Comment from Jim" in browser.contents
    True


Post a comment as anonymous user
--------------------------------
        
Login and post comment as Anonymous 
    
    >>> unprivileged_browser.open(urldoc1)
    
    >>> 'Log in to add comments' in unprivileged_browser.contents
    True

Enable anonymous comment 

    >>> browser.open(portal_url + '/logout')
    >>> browser.open(portal_url + '/login_form')
    >>> browser.getControl(name='__ac_name').value = 'admin'
    >>> browser.getControl(name='__ac_password').value = 'secret'
    >>> browser.getControl(name='submit').click()
    >>> browser.open(portal_url+'/@@discussion-settings') 
    >>> browser.getControl(name='form.widgets.anonymous_comments:list').value = [True] 
    >>> browser.getControl(name='form.buttons.save').click() 
    >>> browser.open(portal_url + '/logout')

Now we can post an anonymous comment.

    >>> unprivileged_browser.open(urldoc1)
    >>> unprivileged_browser.getControl(name='form.widgets.text').value = "This is an anonymous comment"
    >>> unprivileged_browser.getControl(name='form.buttons.comment').click()
 
    >>> '<span>Anonymous</span>' in unprivileged_browser.contents
    True
    
    >>> 'says' in unprivileged_browser.contents
    True
    
    >>> 'This is an anonymous comment' in unprivileged_browser.contents
    True

Make sure special characters work as well.

    >>> unprivileged_browser.open(urldoc1)
    >>> unprivileged_browser.getControl(name='form.widgets.author_name').value = "Tarek Ziadé"
    >>> unprivileged_browser.getControl(name='form.widgets.text').value = "This is an äüö comment"
    >>> unprivileged_browser.getControl(name='form.buttons.comment').click()

    >>> 'Tarek Ziadé' in unprivileged_browser.contents
    True
    
    >>> 'says' in unprivileged_browser.contents
    True
    
    >>> 'This is an äüö comment' in unprivileged_browser.contents
    True


Reply to an existing comment
----------------------------

Check that there is no existing direct reply to a comment.

    >>> 'replyTreeLevel1' in browser.contents
    False

Find a comment id to reply to.

    >>> browser.open(urldoc1)
    >>> import re
    >>> comment_div = re.findall('<div.*?.class="comment.*?>', browser.contents)[0]
    >>> id = re.findall('"([^"]*)"', comment_div)[2]

Post a reply to an existing comment.
    
    >>> browser.getControl(name='form.widgets.in_reply_to').value = id
    >>> browser.getControl(name='form.widgets.text').value = "Reply comment"
    >>> browser.getControl(name='form.buttons.comment').click()

Check that the reply has been posted properly.

    >>> 'Reply comment' in browser.contents
    True
    
    >>> 'replyTreeLevel1' in browser.contents
    True


Post a comment with comment review workflow enabled
---------------------------------------------------

Enable the 'comment review workflow' for comments.
    
    >>> portal.portal_workflow.setChainForPortalTypes(('Discussion Item',), ('comment_review_workflow'),)
    >>> portal.portal_workflow.getChainForPortalType('Discussion Item')
    ('comment_review_workflow',)

We need to commit the transaction, otherwise setting the workflow will not work.

    >>> import transaction
    >>> transaction.commit()

Post comment as anonymous user.

    >>> unprivileged_browser.open(urldoc1)
    >>> unprivileged_browser.getControl(name='form.widgets.text').value = "Comment review workflow comment"
    >>> unprivileged_browser.getControl(name='form.buttons.comment').click()

Make sure the comment has not been published.

    >>> 'Comment review workflow comment' not in unprivileged_browser.contents
    True

Make sure the user gets a notification that the comment awaits moderator 
approval.    

    >>> 'Your comment awaits moderator approval' in unprivileged_browser.contents
    True


Regression Test
---------------

Make sure we still can edit the content object after a comment has been posted.
This is a regression test for http://dev.plone.org/plone/ticket/11157 
(TypeError: Can't pickle objects in acquisition wrappers).

Login as admin.

    >>> browser.open(portal_url + '/logout')
    >>> browser.open(portal_url + '/login_form')
    >>> browser.getControl(name='__ac_name').value = 'admin'
    >>> browser.getControl(name='__ac_password').value = 'secret'
    >>> browser.getControl(name='submit').click()
    
Edit the content object.

    >>> browser.open(urldoc1 + "/edit")
    >>> browser.getControl(name='text').value = "Lorem ipsum"
    >>> browser.getControl(name='form.button.save').click()

Make sure the edit was successful.
        
    >>> 'Lorem ipsum' in browser.contents
    True
