Getting started with Unittests for BrowserViews
|
|
Hi,
I've finally got some time to work on my browser view for folders.
Based on Yuppie's doctest I've started writing a unittest testsuite so
that I can write the tests for the missing functionality and learn
more about unittest as I go along but I'm stumbling at the first
hurdle: what's the best way to call my view? Directly from the view
class or as Multiadapter? If it is the latter what's the correct call
for this as I don't seem to be able to get it right in the zope shell:
>>> folder = site.subfolder
>>> folder
<PortalFolder at /CMFDefault/subfolder>
>>> getMultiAdapter((folder, request), IBrowserPublisher,
name=u"contents.html")
Traceback (most recent call last):
File "<stdin>", line 1, in ?
File "/Users/charlieclark/CMF-Sandbox/cmf-trunk/eggs/
zope.component-3.4.0-py2.4.egg/zope/component/_api.py", line 103, in
getMultiAdapter
raise ComponentLookupError(objects, interface, name)
zope.component.interfaces.ComponentLookupError: ((<PortalFolder at /
CMFDefault/subfolder>, <zope.publisher.browser.TestRequest instance
URL=http://127.0.0.1>), <InterfaceClass
zope.publisher.interfaces.browser.IBrowserPublisher>, u'contents.html')
but
>>> from Products.CMFDefault.browser.new_folder import ContentsView
>>> view = ContentsView(folder, request)
>>> IBrowserPublisher.providedBy(viw)
True
I've noticed that many of the tests use a DummyRequest dictionary but
using an instance of this doesn't work either.
This is the stub of my testsuite:
import unittest
from zope.component import getSiteManager
from zope.component import getMultiAdapter
from zope.publisher.browser import TestRequest
from Products.CMFCore.PortalFolder import PortalFolder
from Products.CMFCore.tests.base.dummy import DummySite
from Products.CMFCore.tests.base.dummy import DummyTool
from Products.CMFCore.interfaces import IPropertiesTool
class FolderBrowserViewTests(unittest.TestCase):
def setUp(self):
"""Setup a site"""
# maybe there is a base class for this?
self.site = site = DummySite('site')
self.sm = getSiteManager()
mtool = site._setObject('portal_membership', DummyTool())
ptool = site._setObject('portal_properties', DummyTool())
self.sm.registerUtility(ptool, IPropertiesTool)
ttool = site._setObject('portal_types', DummyTool())
utool = site._setObject('portal_url', DummyTool())
folder = PortalFolder('test')
site._setObject('test', folder)
self.context = folder
def test_view():
request = TestRequest()
view = getMultiAdapter((self.context, request),
'contents.html') # will fail
def test_suite():
suite = unittest.TestSuite)
suite.addTest(unittest.makeSuite(FolderBrowserViewTests))
return suite
I'm very grateful for any suggestions.
Charlie
