>>> from plone.app.testing import TEST_USER_ID
    >>> from plone.app.testing import TEST_USER_NAME
    >>> from plone.app.testing import TEST_USER_PASSWORD
    >>> from plone.app.testing import setRoles
    >>> from plone.testing.z2 import Browser
    >>> import transaction

    >>> portal = layer['portal']
    >>> app = layer['app']
    >>> setRoles(portal, TEST_USER_ID, ['Manager'])


Some Tests
----------

Just use the behavior ``plone.app.versioningbehavior.behaviors.IVersionable``
in your dexterity content type::

    >>> from plone.dexterity.fti import DexterityFTI
    >>> fti = DexterityFTI('TestingType',
    ...                    factory='TestingType')
    >>> fti.behaviors = (
    ...         'plone.app.dexterity.behaviors.metadata.IBasic',
    ...         'plone.app.versioningbehavior.behaviors.IVersionable',
    ... )
    >>> portal.portal_types._setObject('TestingType', fti)
    'TestingType'
    >>> schema = fti.lookupSchema()


We have to setup versioning for this content type by visiting the plone
configuration panel for content types (/@@types-controlpanel) and enable
automatic versioning for our content type.
For this test we set this configuration manually::

    >>> from Products.CMFCore.utils import getToolByName
    >>> pr = getToolByName(portal, 'portal_repository')
    >>> versionable_types = pr.getVersionableContentTypes()
    >>> versionable_types.append('TestingType')
    >>> pr.setVersionableContentTypes(versionable_types)
    >>> for policy_id in ('at_edit_autoversion', 'version_on_revert'):
    ...     pr.addPolicyForContentType('TestingType', policy_id)
    >>> transaction.commit()

Create a new Browser and connect it::

    >>> browser = Browser(app)
    >>> browser.handleErrors = False
    >>> browser.addHeader('Authorization', 'Basic %s:%s' % (TEST_USER_NAME, TEST_USER_PASSWORD))


Now we should be able to create a new TestingType-object::

    >>> browser.open('http://nohost/plone/folder_factories')
    >>> 'TestingType' in browser.contents
    True
    >>> browser.getControl("TestingType").click()
    >>> browser.getControl("Add").click()
    >>> browser.url
    'http://nohost/plone/++add++TestingType'
    >>> browser.getControl('Title').value = 'Blubb'
    >>> browser.getControl('Save').click()
    >>> browser.url
    'http://nohost/plone/testingtype/view'

The 'changeNote' field should not be visible in the view::

    >>> 'changeNote' in browser.contents
    False
    >>> 'Change Note' in browser.contents
    False

We should be able to access the object, it should provide the marker
interface ``plone.app.versioningbehavior.behaviors.IVersioningSupport``::

    >>> obj = portal.get('testingtype')
    >>> from plone.app.versioningbehavior.behaviors import IVersioningSupport
    >>> IVersioningSupport.providedBy(obj)
    True


After creating the object we wan't to create a new version by simply editing it::

    >>> browser.open('http://nohost/plone/testingtype/edit')
    >>> browser.getControl('Title').value = 'Blubb2'
    >>> field = browser.getControl(name='form.widgets.IVersionable.changeNote')
    >>> field.value = 'just a test'
    >>> browser.getControl(name='form.buttons.save').click()
    >>> browser.url
    'http://nohost/plone/testingtype'


Now we should have at least one version::

    >>> obj = portal.get('testingtype')
    >>> pa = portal.portal_archivist
    >>> history = pa.getHistoryMetadata(obj)
    >>> history.getLength(countPurged=False) > 0
    True


And we should be able to list the versions::

    >>> browser.open('http://nohost/plone/testingtype/versions_history_form')
    >>> 'just a test' in browser.contents
    True


A freshly created object should have a initial version::

    >>> browser.open('http://nohost/plone/++add++TestingType')
    >>> browser.getControl('Title').value = 'Init test'
    >>> browser.getControl(name='form.widgets.IVersionable.changeNote') \
    ...     .value = 'initial change note'
    >>> browser.getControl(name='form.buttons.save').click()
    >>> browser.url
    'http://nohost/plone/testingtype-1/view'


Now we should have one - and only one - version::

    >>> obj = portal.get('testingtype-1')
    >>> pa = portal.portal_archivist
    >>> history = pa.getHistoryMetadata(obj)
    >>> history.getLength(countPurged=False)
    1


And we should see our comment on the versions listing later...

    >>> browser.open('http://nohost/plone/testingtype-1/versions_history_form')
    >>> 'initial change note' in browser.contents
    True


It should also be possible to copy/paste an existing content::

    >>> browser.open('http://nohost/plone/testingtype')
    >>> browser.getLink('Copy').click()
    >>> browser.open('http://nohost/plone/')
    >>> browser.getLink('Paste').click()
    >>> 'copy_of_testingtype' in portal.objectIds()
    True


After pasting, we can create a new version by simply editing it::

    >>> browser.open('http://nohost/plone/copy_of_testingtype/edit')
    >>> browser.getControl('Title').value = 'Dup'
    >>> field = browser.getControl(name='form.widgets.IVersionable.changeNote')
    >>> field.value = 'Edited the duplicate'
    >>> browser.getControl(name='form.buttons.save').click()
    >>> browser.url
    'http://nohost/plone/copy_of_testingtype'


Dexterity Containers
====================
We should also be able to use versionig for dexterity contents in dexterity containers.


Create a container FTI::

    >>> container_fti = DexterityFTI(
    ...     'DemoContainer',
    ...     klass='plone.dexterity.content.Container',
    ...     filter_content_types=False,
    ...     factory='DemoContainerMyFolder',
    ...     behaviors = ('plone.app.dexterity.behaviors.metadata.IBasic',),
    ...     )

    >>> portal.portal_types._setObject('DemoContainer', container_fti)
    'DemoContainer'
    >>> container_schema = fti.lookupSchema()
    >>> transaction.commit()


Create a container object::

    >>> browser.open('http://nohost/plone/++add++DemoContainer')
    >>> browser.getControl('Title').value = 'MyFolder'
    >>> browser.getControl(name='form.buttons.save').click()
    >>> browser.url
    'http://nohost/plone/democontainer/view'


Now we add a versioned object to the container::

    >>> browser.open('http://nohost/plone/democontainer/++add++TestingType')
    >>> browser.getControl('Title').value = 'My versioned object'
    >>> browser.getControl(name='form.widgets.IVersionable.changeNote').value = 'created a object'
    >>> browser.getControl(name='form.buttons.save').click()
    >>> browser.url
    'http://nohost/plone/democontainer/testingtype/view'


So let's see the version history. There should be one version with the comment
"created a object"::

    >>> obj = portal.get('democontainer').get('testingtype')
    >>> obj
    <Item at /plone/democontainer/testingtype>
    >>> pa = portal.portal_archivist
    >>> history = pa.getHistoryMetadata(obj)
    >>> history.getLength(countPurged=False)
    1
    >>> browser.open('http://nohost/plone/democontainer/testingtype/versions_history_form')
    >>> 'created a object' in browser.contents
    True


Dexterity containers should also be versionable.

Let's create a new versioned container FTI::

    >>> versioned_container_fti = DexterityFTI(
    ...     'VersionedContainer',
    ...     klass='plone.dexterity.content.Container',
    ...     filter_content_types=False,
    ...     glboal_allow=True,
    ...     factory='VersionedContainer',
    ...     )
    >>> versioned_container_fti.behaviors = (
    ...         'plone.app.dexterity.behaviors.metadata.IBasic',
    ...         'plone.app.versioningbehavior.behaviors.IVersionable',
    ... )
    >>> portal.portal_types._setObject('VersionedContainer', versioned_container_fti)
    'VersionedContainer'
    >>> versioned_container_schema = versioned_container_fti.lookupSchema()

Enable versioning for the new content type::

    >>> pr = getToolByName(portal, 'portal_repository')
    >>> versionable_types = pr.getVersionableContentTypes()
    >>> versionable_types.append('VersionedContainer')
    >>> pr.setVersionableContentTypes(versionable_types)
    >>> for policy_id in ('at_edit_autoversion', 'version_on_revert'):
    ...     pr.addPolicyForContentType('VersionedContainer', policy_id)
    >>> transaction.commit()

Let's Create a versioned container object on the portal::

    >>> browser.open('http://nohost/plone/++add++VersionedContainer')
    >>> browser.getControl('Title').value = 'Versioned container one'
    >>> browser.getControl(name='form.widgets.IVersionable.changeNote').value = 'my change note'
    >>> browser.getControl(name='form.buttons.save').click()
    >>> browser.url
    'http://nohost/plone/versionedcontainer/view'


Do we have a initial version?

    >>> obj = portal.get('versionedcontainer')
    >>> obj
    <Container at /plone/versionedcontainer>
    >>> pa = portal.portal_archivist
    >>> history = pa.getHistoryMetadata(obj)
    >>> history.getLength(countPurged=False)
    1
    >>> browser.open('http://nohost/plone/versionedcontainer/versions_history_form')
    >>> 'my change note' in browser.contents
    True


Another versioned container should be addable::

    >>> browser.open('http://nohost/plone/versionedcontainer/folder_factories')
    >>> 'VersionedContainer' in browser.contents
    True


Now we try to add another versioned container in the previously created versioned container::
    >>> browser.open('http://nohost/plone/versionedcontainer/++add++VersionedContainer')
    >>> browser.getControl('Title').value = 'Versioned container two'
    >>> browser.getControl(name='form.widgets.IVersionable.changeNote').value = 'another change note'
    >>> browser.getControl(name='form.buttons.save').click()


So, we should have the initial version::

    >>> parent = portal['versionedcontainer']
    >>> obj = parent['versionedcontainer']
    >>> obj
    <Container at /plone/versionedcontainer/versionedcontainer>
    >>> pa = portal.portal_archivist
    >>> history = pa.getHistoryMetadata(obj)
    >>> history.getLength(countPurged=False)
    1
    >>> browser.open('http://nohost/plone/versionedcontainer/versionedcontainer/versions_history_form')
    >>> 'another change note' in browser.contents
    True

Check that the parent does not get versioned inappropriately.

    >>> history = pa.getHistoryMetadata(parent)
    >>> history.getLength(countPurged=False)
    1
