sorry for the missed presentation at Puppet User Group Berlin, I'll make it one day or another and I'll share the slides at least ;) I'll be very happy to discuss further the testing topic, because testing is also very important to us. Actually we do lots of testing on our manifests (but not with rspec) and catalogs, and precisely I think that puppet catalog-diff [1] is the key piece in the pipeline for us, because it shows us for real what's actually changing with every commit we push to our manifests, plus the noop runs before merging to prod give us the final safe net to be sure we don't get any unexpected change in production. For the last 8 months or so it's been working surprisingly well for us and I'm really willing to share our experience with the community and also getting and suggestions about how to improve it even further. By the way, I'm another one that's not so convinced about the rspec tests value, to me seems that the unit tests themselves are much less relevant for a declarative-like language like Puppet. I mean, there's no 'design' that has to emerge by the unit tests getting green, in our team we already share a defined design for module structure, and, say, if the coder write the spec for a file to be there, I don't see why I should trust that more than a definition of that same thing in the manifest itself, hence the feeling of code duplication with no real value added. What I can see very clearly for normal software development, those values coming from TDD, I can't see easily for Puppet manifests writing. Something like Beaker [2] is what we'd like to add to our testing pipeline, i.e. running tests for the full stack in a VM, but again, stil more then willing to change my mind about rspec-puppet ;) [1] https://github.com/ripienaar/puppet-catalog-diff [2] https://github.com/puppetlabs/beaker/wiki/Overview -- http://about.me/alexanderfortin -- You received this message because you are subscribed to the Google Groups "Puppet Users" group.
