What you need when you get cranky is a nice spanking. ;) Regarding junit based tests in the ejb3 project, they mainly test minute functionality (avoid NPEs also), define input/output from the functionality etc. Testing functionality in small bits can reveal issues that integration tests will not or take a long long time in resolving. The issue is the effort in isolating the functionality in bits that need to be unit tested. You have got to start sometime in getting there. :) View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4135342#...
