Without wanting to bang my own drum too much, I just co-authored an entire book which covers these topics in detail: Continuous Delivery http://www.amazon.com/gp/product/0321601912?tag=contindelive-20 On 15 November 2010 07:58, Ron Wheeler [via Maven] < ml-node+3265918-383914585-143...@n5.nabble.com<ml-node%2b3265918-383914585-143...@n5.nabble.com> > wrote: > On 15/11/2010 10:41 AM, Benson Margulies wrote: > > Ron, > > > > It's not too hard to set up a CI process (e.g. on Hudson) that tests > > the latest version of everything.
