If you are running java5 or higher, there's a good chance you can just drop in surefire2.5 and junit-4.8.1, without making any code changes at all. Although I haven't tested this specifically, I think it should work.
You can read about how to do it here - I'll try to get parts of it into some official documentation once I get the karma and find out where ;) In the meantime there's only the javadoc in the plugin. http://incodewetrustinc.blogspot.com/2010/01/run-your-junit-tests-concurrently-with.html Kristian On Fri, 2010-01-15 at 16:39 +0000, Colm O'Donnell wrote: > Thanks for your prompt response. > > We are using junit 3.8 unfortunately.
