[Zope3-checkins] CVS: Zope3/src/zope/app/services/tests - test_registration.py:1.1

[Anthony Baxter]

Update of /cvs-repository/Zope3/src/zope/app/services/tests
In directory cvs.zope.org:/tmp/cvs-serv13561/src/zope/app/services/tests

Added Files:
	test_registration.py 
Log Message:
Moved the Registration object from zope.app.index to zope.app.services.hub,
and changed the bootstrap code to add a Registration object if there is not
already one installed. This means that by default the ObjectHub is now 
actually doing something, rather than sitting by itself feeling lonely.

When a Registration object is added by bootstrap, it's subscribed by
default.
