Make separate commits for logically separate changes. + + Please break your commits down into logically consistent units + which include new or changed tests relevant to the rest of the + change. The goal of doing this is to make the diff easier to + read for whoever is reviewing your code. In general, the easier + your diff is to read, the more likely someone will be happy to + review it and get it into the code base. + + If you are going to refactor a piece of code, please do so as a + separate commit from your feature or bug fix changes. + + We also really appreciate changes that include tests to make + sure the bug is not re-introduced, and that the feature is not + accidentally broken. + + Describe the technical detail of the change(s). If your + description starts to get too long, that is a good sign that you + probably need to split up your commit into more finely grained + pieces. + + Commits which plainly describe the things which help + reviewers check the patch and future developers understand the + code are much more likely to be merged in with a minimum of + bike-shedding or requested changes. Ideally, the commit message + would include information, and be in a form suitable for + inclusion in the release notes for the version of Puppet that + includes them. + + Please also check that you are not introducing any trailing + whitespace or other "whitespace errors". You can do this by + running "git diff --check" on your changes before you commit. + + 2. Sending your patches + + To submit your changes via a GitHub pull request, we _highly_ + recommend that you have them on a topic branch, instead of + directly on "master". + It makes things much easier to keep track of, especially if + you decide to work on another thing before your first change + is merged in. + + GitHub has some pretty good + [general documentation](http://help.github.com/) on using + their site. They also have documentation on + [creating pull requests](https://help.github.com/articles/creating-a-pull-request-from-a-fork/). + + In general, after pushing your topic branch up to your + repository on GitHub, you can switch to the branch in the + GitHub UI and click "Pull Request" towards the top of the page + in order to open a pull request. + + 3. Update the related JIRA issue. + + If there is a JIRA issue associated with the change you + submitted, then you should update the ticket to include the + location of your branch, along with any other commentary you + may wish to make. + +# Testing + +## Getting Started + +Our Puppet modules provide [`Gemfile`](./Gemfile)s, which can tell a Ruby package manager such as [bundler](http://bundler.io/) what Ruby packages, +or Gems, are required to build, develop, and test this software. + +Please make sure you have [bundler installed](http://bundler.io/#getting-started) on your system, and then use it to +install all dependencies needed for this project in the project root by running + +```shell +% bundle install --path .bundle/gems +Fetching gem metadata from https://rubygems.org/........ +Fetching gem metadata from https://rubygems.org/.. +Using rake (10.1.0) +Using builder (3.2.2) +-- 8><-- many more --><8 -- +Using rspec-system-puppet (2.2.0) +Using serverspec (0.6.3) +Using rspec-system-serverspec (1.0.0) +Using bundler (1.3.5) +Your bundle is complete! +Use `bundle show [gemname]` to see where a bundled gem is installed. +``` + +NOTE: some systems may require you to run this command with sudo. + +If you already have those gems installed, make sure they are up-to-date: + +```shell +% bundle update +``` + +## Running Tests + +With all dependencies in place and up-to-date, run the tests: + +### Unit Tests + +```shell +% bundle exec rake spec +``` + +This executes all the [rspec tests](http://rspec-puppet.com/) in the directories defined [here](https://github.com/puppetlabs/puppetlabs_spec_helper/blob/699d9fbca1d2489bff1736bb254bb7b7edb32c74/lib/puppetlabs_spec_helper/rake_tasks.rb#L17) and so on. +rspec tests may have the same kind of dependencies as the module they are testing. Although the module defines these dependencies in its [metadata.json](./metadata.json), +rspec tests define them in [.fixtures.yml](./fixtures.yml). + +### Acceptance Tests + +Some Puppet modules also come with acceptance tests, which use [beaker][]. These tests spin up a virtual machine under +[VirtualBox](https://www.virtualbox.org/), controlled with [Vagrant](http://www.vagrantup.com/), to simulate scripted test +scenarios. In order to run these, you need both Virtualbox and Vagrant installed on your system. + +Run the tests by issuing the following command + +```shell +% bundle exec rake spec_clean +% bundle exec rspec spec/acceptance +``` + +This will now download a pre-fabricated image configured in the [default node-set](./spec/acceptance/nodesets/default.yml), +install Puppet, copy this module, and install its dependencies per [spec/spec_helper_acceptance.rb](./spec/spec_helper_acceptance.rb) +and then run all the tests under [spec/acceptance](./spec/acceptance). + +## Writing Tests + +### Unit Tests + +When writing unit tests for Puppet, [rspec-puppet][] is your best friend. It provides tons of helper methods for testing your manifests against a +catalog (e.g. contain_file, contain_package, with_params, etc). It would be ridiculous to try and top rspec-puppet's [documentation][rspec-puppet_docs] +but here's a tiny sample: + +Sample manifest: + +```puppet +file { "a test file": + ensure => present, + path => "/etc/sample", +} +``` + +Sample test: + +```ruby +it 'does a thing' do + expect(subject).to contain_file("a test file").with({:path => "/etc/sample"}) +end +``` + +### Acceptance Tests + +Writing acceptance tests for Puppet involves [beaker][] and its cousin [beaker-rspec][]. A common pattern for acceptance tests is to create a test manifest, apply it +twice to check for idempotency or errors, then run expectations. + +```ruby +it 'does an end-to-end thing' do + pp = <<-EOF + file { 'a test file': + ensure => present, + path => "/etc/sample", + content => "test string", + } + + apply_manifest(pp, :catch_failures => true) + apply_manifest(pp, :catch_changes => true) + +end + +describe file("/etc/sample") do + it { is_expected.to contain "test string" } +end + +``` + +# If you have commit access to the repository + +Even if you have commit access to the repository, you still need to go through the process above, and have someone else review and merge +in your changes. The rule is that **all changes must be reviewed by a project developer that did not write the code to ensure that +all changes go through a code review process.** + +The record of someone performing the merge is the record that they performed the code review. Again, this should be someone other than the author of the topic branch. + +# Get Help + +### On the web +* [Puppet help messageboard](http://puppet.com/community/get-help) +* [Writing tests](https://docs.puppet.com/guides/module_guides/bgtm.html#step-three-module-testing) +* [General GitHub documentation](http://help.github.com/) +* [GitHub pull request documentation](http://help.github.com/send-pull-requests/) + +### On chat +* Slack (slack.puppet.com) #forge-modules, #puppet-dev, #windows, #voxpupuli +* IRC (freenode) #puppet-dev, #voxpupuli + + +[rspec-puppet]: http://rspec-puppet.com/ +[rspec-puppet_docs]: http://rspec-puppet.com/documentation/ +[beaker]: https://github.com/puppetlabs/beaker +[beaker-rspec]: https://github.com/puppetlabs/beaker-rspec
