[Zope3-checkins] CVS: Zope3/lib/python/Zope/Event/tests - PlacelessSetup.py:1.2

[Jim Fulton]

Update of /cvs-repository/Zope3/lib/python/Zope/Event/tests
In directory cvs.zope.org:/tmp/cvs-serv8384/lib/python/Zope/Event/tests

Added Files:
	PlacelessSetup.py 
Log Message:
Many components now need to generate events. This means that an event
service needs to be in place when testing. For this reason, I've
refactored PlacelessSetup to include events.

- I added a PlacelessSetup in Zope.Event.tests.

  This module also registers a subscriber that collects all events in
  a list and a function for getting all of the events that match an
  optional event type or filter. This is useful so that component
  tests can include tests to make sure that the proper events are
  being fired.

- I added a PlacelessSetup in Zope.App.tests that combines the
  PlacelessSetup from Zope.App.ComponentArchitecture and Zope.Event.

- I changed all the modules that imported
  Zope.ComponentArchitecture.tests.PlacelessSetup to import
  Zope.App.tests.PlacelessSetup.
