Scott Hadfield has posted screen shots for the load test project. Load test is build on top of Drupal's simple test suite.
This shows how load tests can be automated by having various states, each with a defined set of modules.
States can be swtiched remotely too, which is very useful when running the test in conjunction with a laod test tool, such as Apache Benchmark (ab).
This tool should prove helpful in things like benchmarking various configurations and patches.
Check out that module from Scott's sandbox (hadsie), and run a few tests. It is really a useful tool.
Note: Khalid of 2bits is the mentor for Scott for this project. Thanks go to Rok Zlender and Owen Barton for their invaluable co-mentoring as well.
