Rspec

Take a look that the Gemfile that was generated with your module.

# /vagrant/users/Gemfile
source 'https://rubygems.org'

puppetversion = ENV.key?('PUPPET_VERSION') ? "#{ENV['PUPPET_VERSION']}" : ['>= 3.3']
gem 'puppet', puppetversion
gem 'puppetlabs_spec_helper', '>= 0.8.2'
gem 'puppet-lint', '>= 1.0.0'
gem 'facter', '>= 1.7.0'

Within the declared dependencies you will see the puppetlabs_spec_helper gem. This gem contains dependencies that will help us test our modules. Please take a look a the README [1] file from the project's github repository.

Inside the dependencies of puppetlabs_spec_helper is the rspec gem [2].

Rspec provides a way to describe and test Ruby code. And with the help of the rspec-puppet gem [3], we should be able to test the syntax, dependency and manifest resolution of our Puppet code.
