Dominic,

Have you tried the FoxRunner test harness? Its available from the following url.

http://www.cal.de/cgi-bin/index.pl?lang=e&js=1&content=../e/prod_foxrunner1.html

Its my belief that you get the source code to the VFP7 test harness so there may be room for expansion if the VFP7 one is missing functionality.

HTH
