The 2nd part of the byteman tutorial has been released. It explains how to use Byteman in combination with TestNG and JUnit. It is based on a sample application provided with build scripts showing how to automate the build and test process from either maven or ant. Please take a look at the tutorial at: http://community.jboss.org/wiki/FaultInjectionTestingWithByteman#top and vote it up on DZone at: http://www.dzone.com/links/byteman_fault_injection_tutorial.html The release of the tutorial accompanies the release of Byteman 2.0.0 http://bytemanblog.blogspot.com/ It includes a small number of bug fixes and new features and is available from the Byteman download page. If you are using Byteman from maven then the 2.0.0 jars are available via the JBoss repository. regards, Andrew Dinn -----------
