[Zope-Checkins] CVS: Zope3/lib/python/Zope/PageTemplate/tests - testViewZPT.py:1.1.2.1

[Steve Alexander]

Update of /cvs-repository/Zope3/lib/python/Zope/PageTemplate/tests
In directory cvs.zope.org:/tmp/cvs-serv27024/lib/python/Zope/PageTemplate/tests

Added Files:
      Tag: Zope-3x-branch
	testViewZPT.py 
Log Message:
Test written for ViewZPT.py.
After consulting with Jim, removed the change that allowed the instance
passed in not to have a getContext method.
It turned out to be really crufty to get rid of namespace['here'], as it
is set to instance in ZPT.pt_getContext, where ZPT is the base class of
ViewZPT.
