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.
-
Fork the repo.
-
Run the tests. We only take pull requests with passing tests, and it's great to know that you have a clean slate.
-
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.
-
Make the test pass.
-
Push to your fork and submit a pull request.
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.
Install the dependencies like so...
```shell
bundle install
```
The test suite will run Puppet Lint, rubocop and Puppet Syntax to check various syntax and style things. You can run these locally with:
```shell
bundle exec rake lint
bundle exec rake syntax
bundle exec rake rubocop
```
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:
```shell
bundle exec rake spec
```
Note also you can run the syntax, style and unit tests in one go with:
```shell
bundle exec rake test
```
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 Litmus.
Litmus fires up a new docker instance using hypervisor of your choice and runs a series of simple tests against it after applying the module. You can run our Litmus acceptance tests with following commands:
```shell
bundle exec rake 'litmus:provision[docker, ubuntu:18.04]'
bundle exec rake litmus:install_agent
bundle exec rake litmus:install_module
bundle exec rake litmus:acceptance:parallel
```
The above commands will create a container using docker and ubuntu version 18.04, install puppet and the uamsclient module and will start executing the acceptance tests. To run against an another host, follow the steps here.
To run against a set of environments, modify the provision.yaml and create your own list of environments. For example, the below command will create a set of environments as defined under the label release_checks:
```shell
bundle exec rake 'litmus:provision_list[release_checks]'
```
Then you can check the list of created containers by running the command
```shell
docker ps
```
