This module has grown over time based on a range of contributions from people using it. If you follow these contributing guidelines your patch will likely make it into a release a little quicker.

Contributing

  1. Fork the repo.

  2. Run the tests. We only take pull requests with passing tests, and it's great to know that you have a clean slate.

  3. Add a test for your change. Only refactoring and documentation changes require no new tests. If you are adding functionality or fixing a bug, please add a test.

  4. Make the test pass.

  5. Push to your fork and submit a pull request.

Dependencies

The testing and development tools have a bunch of dependencies, all managed by Bundler according to the Puppet support matrix.

By default the tests use a baseline version of Puppet.

If you have Ruby 2.x or want a specific version of Puppet, you must set an environment variable such as:

export PUPPET_VERSION="~> 3.2.0"

Install the dependencies like so...

bundle install

Syntax and style

The test suite will run Puppet Lint and Puppet Syntax to check various syntax and style things. You can run these locally with:

bundle exec rake lint
bundle exec rake syntax

Running the unit tests

The unit test suite covers most of the code, as mentioned above please add tests if you're adding new functionality. If you've not used rspec-puppet before then feel free to ask about how best to test your new feature. Running the test suite is done with:

bundle exec rake spec

Note also you can run the syntax, style and unit tests in one go with:

bundle exec rake test

Automatically run the tests

During development of your puppet module you might want to run your unit tests a couple of times. You can use the following command to automate running the unit tests on every change made in the manifests folder.

bundle exec guard

Integration tests

The unit tests just check the code runs, not that it does exactly what we want on a real machine. For that we're using Beaker.

Beaker fires up a new virtual machine (using Vagrant) and runs a series of simple tests against it after applying the module. You can run our Beaker tests with:

bundle exec rake beaker

This will use the host described in spec/acceptance/nodeset/default.yml by default. To run against another host, set the BEAKER_set environment variable to the name of a host described by a .yml file in the nodeset directory. For example, to run against CentOS 6.4:

BEAKER_set=centos-64-x64 bundle exec rake acceptance

If you don't want to have to recreate the virtual machine every time you can use BEAKER_destroy=no and BEAKER_provision=no. On the first run you will at least need BEAKER_provision set to yes (the default). The Vagrantfile for the created virtual machines will be in .vagrant/beaker_vagrant_files.
