Not having a physical server handy to run Tsung isn’t a big obstacle; I just used an Amazon EC2 instance (an xlarge turned out to be more than enough, you could probably get 100s of users on a medium), which due to being rentable by the hour is great for a short-term need like occasional load-testing. I put one of Alestic’s Ubuntu images on the EC2 instance, and then it’s just a few short steps to install Tsung on the machine (we’ll call it ‘tsunghost’): Update: Ben says in the comments, “Tsung now has Ubuntu packages, so you don’t need to compile.
Rafael Dohms » PHPT: Writing tests for PHP. This year the PHP Community promoted the PHPTestFest in various places around the globe and it was a success.
