Testing Puppet code with jobs

Sections

Jobs are fully customizable tests for your Puppet code. You can create a job that runs any sort of test you wish, from module validation to linting.

Important: Make sure you have set up job hardware and installed any needed software (such as Docker or Puppet Development Kit) before you attempt add one of these jobs to a pipeline.

What is a job?

In Continuous Delivery for PE, jobs are tests for your Puppet code. Jobs are created and stored in the web UI, where you can run them on demand and add them to an automated pipeline that runs tests every time new code is committed to a repository.

Jobs are fully customizable and can be written to test any aspect of your code. Jobs can be written to take advantage of Puppet Development Kit (PDK) and other testing tools created and maintained by the Puppet community, such as:

  • rspec-puppet

  • onceover

  • puppet-lint

  • rspec-puppet-facts

It's important to be aware of any prerequisites or dependencies needed to run your jobs, and to ensure that your job hardware has the necessary software, operating systems, and other resources installed before attempting to run the job.

Pre-built job reference

Continuous Delivery for PE offers users six pre-built Docker-based jobs for testing control repos and modules. These jobs run inside a Docker container, and must be run on job hardware on which you've set a Docker capability.

Sample non-Docker-based module jobs

This section lists sample jobs that you can use with Continuous Delivery for PE. These jobs can be entered as-is into the New Job creation screen in the Continuous Delivery for PE web UI, or you can make alterations to suit your deployment's needs.

Note: When composing a non-Docker-based job, the $REPO_DIR environment variable can be used to reference the directory that houses the relevant module repo.

Puppet Development Kit validation tests

Use the sample jobs below to validate your module code against PDK. Select the version appropriate to your operating system.  

In order to use this job successfully, you must:

  • Install PDK on your job hardware

  • Install puppet-agent on your job hardware

Job name Description Commands Capabilities
module-pdk-validate-linux Validate via PDK pdk validate LINUX
module-pdk-validate-windows Validate via PDK powershell.exe -c "pdk validate" WINDOWS

Puppet Development Kit rspec-puppet tests

Use the sample jobs below to run unit tests on your module code with rspec-puppet. Select the version appropriate to your operating system.  

In order to use this job successfully, you must:

  • Install PDK on your job hardware

  • Install puppet-agent on your job hardware

      failures+=("$f")
