Views

Test view registration

Test if view has been properly registered:

def test_delete_view_registered(self):
    try:
        getMultiAdapter(
            (self.portal.mi.se.tc, self.request),
            name="delete"
        )
    except:
        self.fail("Delete view is not registered properly.")

Test with getMultiAdapter

Test:

def test_view_is_registered(self):
    # Get the view
    view = getMultiAdapter((self.portal, self.portal.REQUEST), name="create-user")
    # Call the view
    self.assertTrue(view())

Test with restrictedTraverse

Test:

def test_view_is_registered(self):
    view = self.portal.restrictedTraverse('@@list-products')
    self.assertTrue(view)
    self.assertEqual(view(), 'ListProductsView')

Test view with parameter

Test:

def test_autocomplete_tags_view_registered(self):
    self.request.set('term', 'foo')
    view = getMultiAdapter((self.portal, self.request),
                           name="autocomplete-tags")
    self.assertTrue(view())

Test with restrictedTraverse and parameter

Test:

def test_view_with_restrictedTraverse_and_params(self):
    view = self.context.restrictedTraverse("comment-statistics-batch")
    view(query, base_number * i, base_number * (i + 1) - 1)

Test if view is protected

Test:

def test_view_is_protected(self):
    from AccessControl import Unauthorized
    self.logout()
    self.assertRaises(Unauthorized,
                      self.portal.restrictedTraverse,
                      '@@deploymentmanager')

Test if object exists in folder

Test:

def test_object_in_folder(self):
    self.assertFalse('yoda' in self.portal.objectIds())

Test Redirect

Test:

def test_component_view(self):
    self.portal.mi.sec.invokeFactory(
        "TextComponent",
        id="tx",
        title="Text Component 1",
    )
    view = getMultiAdapter(
        (self.portal.mi.sec.tx, self.request),
        name="view"
    )

    view()

    self.assertEqual(
        self.request.response.headers['location'],
        'http://nohost/plone/mi/sec'
    )

Test View HTML Output

Test:

from lxml import html
output = html.fromstring(view())
self.assertEqual(len(output.xpath("/html/body/div")), 1)

Troubleshooting

KeyError: ‘ACTUAL_URL’:

def setUp(self):
    self.portal = self.layer['portal']
    self.request = self.layer['request']
    setRoles(self.portal, TEST_USER_ID, ['Manager'])
    self.portal.invokeFactory('Folder', 'test-folder')
    self.folder = self.portal['test-folder']
    self.request.set('URL', self.folder.absolute_url())
    self.request.set('ACTUAL_URL', self.folder.absolute_url())

def test_view(self):
    view = self.collection.restrictedTraverse('@@RSS')
    self.assertTrue(view())
    self.assertEqual(view.request.response.status, 200)

ComponentLookupError

If a view can not be looked up on a particular context, Plone will raise a ComponentLookupError (because views are multi-adapters), e.g.:

ComponentLookupError: ((<PloneSite at /plone>, <HTTPRequest, URL=http://nohost/plone>), <InterfaceClass zope.interface.Interface>, 'recipes')::

This can be solved for instance by providing a browser layer that has been missing:

def setUp(self):
    self.request = self.layer['request']
    from zope.interface import directlyProvides
    directlyProvides(self.request, IMyCompanyContenttypes)
    ...

AttributeError: @@plone_portal_state

Test View Methods

Test:

def test_method_sections(self):
    self.portal.mi.invokeFactory("Section", id="s1", title="Section 1")
    self.portal.mi.invokeFactory("Section", id="s2", title="Section 2")
    view = getMultiAdapter(
        (self.portal.mi, self.request),
        name="view"
    )

    self.assertEqual(len(view.sections()), 2)
    self.assertEqual(
        [x.title for x in view.sections()]
        [u'Section 1', u'Section 2']
    )

View Status Messages

Test:

def test_delete_comments_sets_status_message(self):
    view = getMultiAdapter(
        (self.portal.mi.se.tc, self.request),
        name="delete"
    )

    view()

    self.assertEqual(
        IStatusMessage(self.request).show()[0].message,
        u'Item deleted'
    )

View Class:

class DeleteComponent(BrowserView):

    def __call__(self):
        section = aq_parent(self.context)
        section.manage_delObjects([self.context.id])
        IStatusMessage(self.context.REQUEST).addStatusMessage(
            _("Item deleted"),
            type="info"
        )
        self.request.response.redirect(section.absolute_url())
