Another remarks: In simulation a lot of java code / actions should NOT be executed, this is configurable (wait for my next part of the language proposal later today). In load test, I think you WANT to execute all code, but maybe mock at some level. So I think, we need a different approach for load testing, even if we may can reuse some stuff from the simulation (like the distributions / probabilities stuff). But just for documentation at the moment, currently I am only working on simulation, not on load testing ;-) View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4092920#...
