Update of /cvs-repository/Zope/lib/python/Products/PluginIndexes/KeywordIndex/tests
In directory cvs.zope.org:/tmp/cvs-serv23103/KeywordIndex/tests

Added Files:
      Tag: tseaver-pxtestcleanup-branch
	testKeywordIndex.py 
Log Message:


 - Refactored tests into subdirectories under their respective packages.

 - Removed dependency of tests on 'execfile( "framework.py" )'

 - TextIndex/TextIndex.py: replaced corrected use of 'insintance', rather
   than using 'type'.

 - Ensured that tests which need to catch logged errors don't leave
   the logger in a hosed state.
