It supports parameterization, capturing of variables in HTTP responses, and response validation using regular expressions. Test scripts may be logically grouped into test sets, allowing them to share variables and captured values. Test sets can be run sequentially, randomly, in a specific thread, or according to a percentage-based weighting. A correlating test runner is also provided, making it easier for you to find and capture values in your HTTP responses. We have successfully used this module to run load tests of more than 300 virtual users, with a scenario involving 21 different webtest scripts recorded in Fiddler.|

"...I recommended The Grinder as the tool to go forward with. It has a simple, clean UI that clearly shows what is going on without trying to do too much, and offers great power and simplicity with its unique Jython-based scripting approach. Jython allows complex scripts to be developed much more rapidly than in more formal languages like Java, yet it can access any Java library or class easily, allowing us to re-use elements of our existing work."
Travis has since assisted with the implementation of slow socket support for The Grinder.

One of my consulting services is helping performance analysts to set up company-internal blogs on their performance activities to help them communicate better with their developers and management. As part of my consulting service I can offer usage and customization tips on The Grinder and a separate data visualization tool to show Grinder test results on their company's intranet. Much of this is in the area of test automation and mining test results.
Here's a link which provides several example web pages on communicating WebLogic 8.1/Grinder testing results. It requires downloading the Java 1.5 plug-in for charting Grinder test results.

TestPros provides load testing and performance tuning services using Grinder. We can provide our services in one or a combination of three ways - remotely via our Internet server farm, at our test labs, or at our customer's location.
For more information:
I run a mailing list for software testers called swtest-discuss. There are a few people there (including me) who are interested in talking about how people do testing for open source projects. I haven't yet found a community of open source testers that cuts across multiple tools/applications.
If you're interested in sharing your experiences in testing open source software, please consider joining swtest-discuss, at least long enough to see if there's any interest in having an on-going forum on this topic. If you do subscribe, please either send me a private email or introduce yourself to the list so we know you're there.

J2EE Performance Testing
I'm pleased to announce the availability of J2EE Performance Testing with BEA WebLogic Server by Peter Zadrozny, Philip Aston and Ted Osborne, originally published by Expert Press and now by APress.
This book uses The Grinder 2 throughout, and indeed was responsible for driving the development of many of The Grinder's features. The book shows how to performance test complete J2EE applications and how to explore key performance issues surrounding the most popular J2EE APIs. The performance tests are carried out using BEA WebLogic Server™, but are generally applicable to any J2EE application server.
Most importantly, the book contains in-depth coverage of The Grinder 2 including a full user guide and case studies showing how to apply The Grinder to real world problems. The testing approach is equally applicable when using The Grinder 3.
Following several requests, I've made the source code for the book available from The Grinder SourceForge page. This source is supplied unsupported and with no warranty.
