Frankfurt/Main - 17.05.2017
On a VM or on your local machine: install rvm or rbenv
Get used to Ruby
- gems
- irb
Make your irb better usable:
gem install wirble
Create your .irbrc file
require 'rubygems'
require 'wirble'
Wirble.init
Wirble.colorize
gem install puppet-lint
Run lint tests
puppet-lint <manifests file>
Check for extensions on http://voxpupuli.org
gem install rspec-puppet
Create rspec-puppet required files
rspec-puppet-init
Modify spec/spec_helper.rb
# spec/spec_helper.rb
require 'rspec-puppet'
fixture_path = File.expand_path(File.join(__FILE__,'..','fixtures'))
RSpec.configure do |c|
c.module_path = File.join(fixture_path, 'modules')
c.manifest_dir = File.join(fixture_path, 'manifests')
end
Add a first spec test in spec/classes/frankfurt-workshop_spec.rb
# spec/classes/frankfurt-workshop_spec.rb
require 'spec_helper'
describe 'frankfurt-workshop', :type => :class do
context 'it should compile' do
it { should compile.with_all_deps }
end
end
Run rspec:
rake rspec
Analyze and fix errors
Don't mess your ruby !!
Uninstall all prior installed gems:
gem uninstall puppet-lint rspec-puppet
Install bundler
gem install bundler
Install gems
bundle install --path vendor
Adopt Rakefile
# Rakefile
require 'puppetlabs_spec_helper/rake_tasks'
Run rake -T with bundler
bundle exec rake -T
bundle exec rake spec
Depending modules are added to .fixtures.yml file:
# .fixtures.yml
fixtures:
symlinks:
'frankfurt-workshop': "#{source_dir}"
repositories:
'stdlib':
repo: 'https://github.com/puppetlabs/puppetlabs-stdlib.git',
ref: '4.16'
Install the puppet facts gem via bundler:
# Gemfile add the following line:
gem 'rspec-puppet-facts'
Install gem using bundler:
bundle install --path vendor
Attention: this one needs a metadata.json file!

require 'spec_helper'
describe 'frankfurt-workshop', :type => :class do
on_supported_os.each do |os, facts|
context "it should compile on #{os}" do
let(:facts) do
facts
end
it { should compile.with_all_deps }
end
end
end
Install beaker
bundle install --path vendor --with-integration
Run beaker integration tests
bundle exec rake beaker
Add tests in spec/acceptance/frankfurt-workshop_spec.rb
# spec/acceptance/frankfurt-workshop_spec.rb
Tests with docker:
if you have worked as non-root (which is more nice)
sudo rpm -Uvh https://yum.puppetlabs.com/puppetlabs-release-pc1-el-7.noarch.rpm
sudo yum install -y puppet-agent
sudo /opt/puppetlabs/bin/puppet module install garethr-docker
sudo /opt/puppetlabs/bin/puppet apply -e 'include docker'
Install retrospec
gem install puppet-retrospec
Get a module without tests (e.g. remove spec folder, Rakefile, Gemfile, .fixtures.yml from this repo
Run retrospec
retrospec -m <modulepath>
Check results
Done.
