Saving graphs from puppet-catalog-test runs?

[Matt Wise]

When we run our puppet-catalog-test runs (https://github.com/invadersmustdie/puppet-catalog-test), we'd like to generate and save the .dot graph files so that we can turn them into images. I don;t know enough about the internal workings of Ruby/Puppet to do this -- but does anyone have any ideas? I'm sure it will require patching puppet-catalog-test

I don't know anything about puppet-catalog-test, but IIRC the Catalog class has a 'to_dot' method on it; you should be able to call that, and just send the output to disk.

If you search for 'dot' or 'to_dot' in the code base, you should be able to track it down pretty quickly, I think.

(It's been ages since I looked at this, but I don't think it's changed much.)
