I need to test application that is just like Net2Phone. Any suggestions especially regarding " Multi User" or stees testing the application. ceratinly there are software that can automate these tasks but I need a very cheap soluion (yes freee solution!!! )
So ball is in ur court now
I don't know that you will find a ceap/free load testing solution. My officemate (Chris Walters) and I have done it using Rational TestStudio. It's really not simple - it's a custom protocol that I don't think any of the load testing tools support at this point.
Chris and I gave a presentation at the Rational User's Conference in August with a demo of testing VoIP. it's called Supporting Unsupported Protocols, and can be found at http://www.perftestplus.com in the presentations section.
So are u suggesting that I should use Rational test studio? but my question is the same is it still a good solution for testing such applications. Like I can manually test at least one channel of the application but what about theother we have no data whats its going to happen when twenty user are using the system simultanuasly.
