105  Revision 1.3 2006/03/24 00:18:46 billhorsman
106  Changes for HSQL 1.8
107
108  Revision 1.2 2004/05/26 17:19:09 brenuart
109  Allow JUnit tests to be executed against another database.
110  By default the test configuration will be taken from the 'testconfig-hsqldb.properties' file located in the org.logicalcobwebs.proxool package.
111  This behavior can be overriden by setting the 'testConfig' environment property to another location.
112
113  Revision 1.1 2003/11/04 13:22:43 billhorsman
114  New test for delegate properties
