If anybody is interested, I've written a quick and rather ugly application for running your ANTS Load tests interactively in a web browser so that you can check the script for potential problems that won't show themselves normally until after you run the test.
If this sounds like something you would use, please have a look at
http://labs.red-gate.com/index.php/Red_ ... ipt_tester
and tell me what you think. There is a separate forum to discuss the program at
...so I would appreciate it if you could place any comments there.
