[Pharo-project] destructive / regression tests

I've been thinking these days on how to implement regression tests. Obviously the core requirement is to launch a separate image and capture terminal output and/or result files. For now I will put them into a separate repository: http://smalltalkhub.com/#!/~Pharo/regression-testing Some question: - Is there a test ConfigurationOf* which can be used to try loading different versions / groups? - Is it ok to rely on OSProcess for now to run launch a separate new image?
