SoakIE – a Web Server Stress Tool with a twist

Last week or so ago a couple of friends in another project in Cognifide has run into a wall while trying to load test their website. the problem was as follows: The website is highly AJAX based – the page merely loads a stub in the initial request but then loads the rest of its data in a dynamic matter therefore a traditional web testing tools are fairly useless. What they tried was to setup a number of Selenium clients to pound the server, but that turned out to be fairly challenging to the machine doing the testing. It was not possible to set up more than 10 clients on a fairly strong machine.

Also there are other limitations like time to wait for the server to timeout and time between clicks, which I am not sure the tool allowed them to adjust. Talking to them I recalled a tool for grabbing website thumbnails long time ago. one way for them would be to to make a batch file with it.

Also it creates and tears down an instance of IE every time, making it’s not optimal for that task.

So a couple of evenings later (and a few back-s and forth-s during the testing sessions) out comes SoakIE:
