[Zope3-checkins] CVS: Zope3/lib/python/Zope/App/RDB/GadflyDA/tests - __init__.py:1.1 testAdapter.py:1.1

[Albertas Agejevas]

Update of /cvs-repository/Zope3/lib/python/Zope/App/RDB/GadflyDA/tests
In directory cvs.zope.org:/tmp/cvs-serv8544/GadflyDA/tests

Added Files:
	__init__.py testAdapter.py 
Log Message:
Added Gadfly DA which was previously in an incorrect CVS module.

Small cleanups (the tests now use a temp directory for creating databases).

Oh, this move is based an agreement between Jim and Stephan Richter that
GadflyDA belongs as a default "batteries included" adapter in Zope3.
