Testing your Chef cookbooks
You know how annoying this is: you tweak a cookbook, upload it to your Chef server, start a Chef run on your node and, boom! It fails. What's even more annoying is that it fails not because a black hole absorbed your node and the whole data center that node lives in, but because you missed a mundane comma in the default recipe of the cookbook you just tweaked. Fortunately, there's a very quick and easy way to find such simple glitches before you go all in and try to run your cookbooks on real nodes.
