Puppet-lint checks your Puppet manifests against the Puppet Labs style
guide and alerts you to any discrepancies.
You can test a single manifest file by running:
puppet-lint <path to file>
If you want to test your entire Puppet manifest directory, you can add
require 'puppet-lint/tasks/puppet-lint' to your Rakefile and then run:
rake lint
