Ansible Automated Testing Demo

This is a sample project to demonstrate different technologies and best practices relating to automating testing in Ansible

Raw Notes

  • Testing Methods

    • Using Ansible assert and fail modules

      • register variables
        • logic to capture data should not change state of system
        • use changed_when: false to avoid erroneous changed count
      • assert or fail based on registered data
        • Continuing on failed asserts/tests to execute all tests
        • use ignore_errors: yes
        • #todo: mkd - settle on yes/no vs true/false

    • Other Frameworks (As time permits)

      • Inspec - ruby
      • ServerSpec - ruby
      • Testinfra - python

  • Where to test

    • Vagrant and Kitchen
    • Docker
    • Public Cloud
    • Actual infrastructure

  • Best Practices

    • How to lay out the tests
      • tasks vs playbooks
      • targeting servers
      • why testing multi-role projects can be hard
      • activating tests via tags, environment variables, etc
    • Test should not alter the state of the system in most cases

  • Gotchas

    • include versus import and tags in the current version of Ansible

  • Refs

  • Misc

    • Testing custom modules is more important
    • code hardening vs automated tests
      • wait_for is a example of hardening

Presentation Summary

An overview of how to implement automated tests to validate the state of systems provisioned using Ansible including best practices, common pitfalls, and various framework options.

Setup
