You can subscribe to events using the @grok.subscribe decorator:
>>> grok.testing.grok(__name__)
>>> manfred = Mammoth('Manfred')
>>> zope.event.notify(ObjectEvent(manfred))
>>> mammoths
['Manfred']
>>> mammoths2
['Manfred']
The decorated event handling function can also be called directly:
>>> mammothAdded(Mammoth('Max'),None)
>>> mammoths
['Manfred', 'Max']
