Currently I have been asked to propose an automated release management solution for a large oracle SOA project. All code is stored on SVN repository and it would be nice if I could suggest something that would build, deploy, run test cases and produced reports for all projects on trunk. I know that I could do that by creating ant or maven scripts, but I would like to know if there is an open source alternative that handles all these complex stuff, without the need of so much coding.
I'm not sure what your requirements are. Are you looking to run tests on your production server?
Or, are you looking for a continuous integration server like Jenkins? Jenkins can run your unit tests every time you do a commit and send you a nice email if you fail any tests. You should only deploy after Jenkins says it is safe to do so. Note, there are other CI systems out there. I happen to use Jenkins at work.
This doesn't actually handle deploying and launching your updated service, but it's probably one step in the sequence.
