I am a commuter and during my commuting I often work on some Grails projects. As Grails users knows, there are tasks that requires a rather big amount of time (re-run an app in non-interactive mode, run a test suite etc…) even on fairly recent hardware. Instead of watching the screen during these interval of time I prefer to lay my eyes somewhere else for at least a couple of good reasons: the first one is that programmer’s eyes are always greedy for some rest, the second one is that I live (and commute through) one of the most beautiful place in the world and taking some relaxing view of the sight is amazing!...

A few day ago I was writing a financial service involving several related domain classes. Under some circumstances I wanted the entire transaction to rollback. According to the documentation, a Grails transaction is rolled back whenever a RuntimeException is thrown during its execution (this is the default behaviour in Grails, but you can configure it to rollback a transaction for whatever exception you want). When I finished I wrote some integration tests to make sure that everything worked as expected....
