The test needs a placeful setup instead of a placeless setup. There is a
method in zope.app.testing.setup that does everything needed.

Change to:
...
from zope.app.testing.setup import placefulSetUp
def setUp(test):
test.globs = {'root': placefulSetUp(True)} # placeful setup
zope.component.eventtesting.setUp(test)
zope.component.provideHandler(updateWeightedItemsContainerOrder)
vocabulary.setVocabularyRegistry(vocabulary.VocabularyRegistry())
vr = vocabulary.getVocabularyRegistry()
vr.register('quotationtool.categorization.categorizableitemdescription',
categorizableItemDescriptionVocabulary)
vr.register('quotationtool.categorization.mode',
modeVocabulary)
vr.register('Interfaces',
InterfacesVocabulary)
