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 more quickly.

Contributing

Please note that this project is released with a Contributor Code of Conduct. By participating in this project you agree to abide by its terms. Contributor Code of Conduct.

  1. Fork the repo.

  2. Create a separate branch for your change.

  3. Run the tests. We only take pull requests with passing tests, and documentation.

  4. 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.

  5. Squash your commits down into logical components. Make sure to rebase against the current master.

  6. Push the branch to your fork and submit a pull request.

Please be prepared to repeat some of these steps as our contributors review your code.

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="~> 4.2.0"

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 validate

It will also run some Rubocop tests against it. You can run those locally ahead of time with:

bundle exec rake rubocop

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.

To run the linter, the syntax checker and the unit tests:

bundle exec rake test

To run your all the unit tests

bundle exec rake spec SPEC_OPTS='--format documentation'

To run a specific spec test set the SPEC variable:

bundle exec rake spec SPEC=spec/foo_spec.rb

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.

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

bundle exec rake acceptance

This will run the tests on the module's default nodeset. You can override the nodeset used, e.g.,

BEAKER_set=centos-7-x64 bundle exec rake acceptance

There are default rake tasks for the various acceptance test modules, e.g.,

bundle exec rake beaker:centos-7-x64
bundle exec rake beaker:ssh:centos-7-x64

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.

The easiest way to debug in a docker container is to open a shell:

docker exec -it -u root ${container_id_or_name} bash
