[wildfly-dev] stress testing and benchmark testing

Hi all, I recently try to find out how to stress testing and benchmark testing wildfly, and as the document ( https://docs.jboss.org/author/display/WFLY8/WildFly+Integration+Testsuite...) states, there should be two folders called "stress" and "benchmark" respectively under testsuite folder. but I can't find them in the latest source code. I wonder if they are not available for community or the document doesn't match the actual code. Regards, Peter Cai
