Subject: testing Five-ish products - msg#00055

Hi all,

What's the "correct" way to do functional tests for a Five-ish product,
I'm trying to do the following:

(apologies for the length, gotta love the amount of kicking Zope 2 needs ;-)

import Globals
import logging
import transaction
import Zope2

from AccessControl.SecurityManagement import newSecurityManager
from AccessControl.SecurityManagement import noSecurityManager
# this import, rather evilly, causes Zope2.bobo_application and Zope2.DB
# to come into existence :-(
from Testing.ZopeTestCase import ZopeLite
from Testing.ZopeTestCase.utils import makerequest
from ZODB import DB
from ZODB.DemoStorage import DemoStorage

state = [Zope2.DB]

def setChickens(db):
# Zope 2 chickens
Globals.BobobaseName = db.getName()
Globals.DB = db
Zope2.DB = db
Globals.UndoManager=db
ZopeLite.DB = db
junk_db, name, version_support = Zope2.bobo_application._stuff
Zope2.bobo_application._stuff = db, name, version_support

def addDB():
global state
previous = state[-1]
storage = DemoStorage(base=previous._storage)
db = DB(storage)
# cluck
db.classFactory = previous.classFactory
# cluck cluck
setChickens(db)
state.append(db)


def removeDB():
global state
db = state.pop()
db.close()
# un-cluck
setChickens(state[-1])

def Zope2SetUp(test):
global state
previous = state[-1]
storage = DemoStorage(base=previous._storage)
db = DB(storage)
# cluck
db.classFactory = previous.classFactory
# cluck cluck
setChickens(db)
state.append(db)
# install product
ZopeLite.installProduct('Five')
ZopeLite.installProduct('twiddler.zope2')

def Zope2TearDown(test):
global state
db = state.pop()
db.close()
# un-cluck
setChickens(state[-1])

def setUp(test):
Zope2SetUp(test)
a = app()
a.manage_addFolder('folder')
test.globs['folder']=a.folder

def test_suite():
return unittest.TestSuite((
DocFileSuite('../readme.txt', optionflags=options,
setUp=setUp,
tearDown=Zope2TearDown),
))

I get the following error:

File "C:\Zope\2.9.4\lib\python\zope\configuration\config.py", line 612,
in execute_actions
callable(*args, **kw)
File "Products\pythonproducts\pythonproducts.py", line 57, in
_registerPackage
_zope_app)
File "C:\Zope\2.9.4\lib\python\App\Product.py", line 497, in
initializeProduct

products=app.Control_Panel.Products
ConfigurationExecutionError: exceptions.AttributeError: 'NoneType'
object has no
attribute 'Control_Panel'
in:
File "lib\python\twiddler\zope2\configure.zcml", line 6.0-6.61
<five:registerPackage package="." initialize=".initialize" />

If I remove the installProduct('Five'), I get the following instead:

File "<doctest readme.txt[0]>", line 1, in ?
folder.manage_addProduct['twiddler.zope2'].addTwiddler('test')
File "C:\Zope\2.9.4\lib\python\App\FactoryDispatcher.py", line 26, in
__getitem__
return self.__bobo_traverse__(None, name)
File "C:\Zope\2.9.4\lib\python\App\FactoryDispatcher.py", line 29, in
__bobo_traverse__
product=self.aq_acquire('_getProducts')()._product(name)
File "C:\Zope\2.9.4\lib\python\App\Product.py", line 69, in _product
def _product(self, name): return getattr(self, name)
AttributeError: twiddler.zope2

Any help greatfully received...

Chris
