PuppetConf 2014

Within the Puppet community we talk a lot about testing modules, with rspec-puppet or, increasingly, with Beaker, but we don't often discuss what a complete infrastructure continuous integration pipeline might look like.

Continuous integration is about bringing all the pieces of a system together as early as possible, to avoid problems with integration later on. That means looking not only at individual modules, but also at how they work together and how we can verify their combined behavior.

This talk will cover:

* Building and testing base images using Puppet, Packer, and Serverspec
* Integration testing collections of modules using Vagrant and Cucumber
* Writing assertions against the state of your infrastructure, based
on data in PuppetDB and from API driven infrastructure
* Automatically generating tests based on what Puppet knows about your
infrastructure

We'll also discuss what features Puppet is missing that would make full system testing easier, and what tools might look like in the future.
