Devopsdays Vancouver 2013 - Test Kitchen

We've come a long way with infrastructure as code and are getting closer to better test frameworks and facilities. Test Kitchen was originally developed with Chef in mind, but it is now becoming a standard across different configuration management tools.

This talk will focus on how Test Kitchen can help you shorten the feedback cycle during the development of infrastructure code and discover how it plays nice with other existing tools like ChefSpec, RSpec Puppet, and Vagrant.

Learn about unit and smoke testing infrastructure as code in a Test Driven Development (TDD) cycle. Besides the technology we will look into the benefits of this faster feedback cycle and the current/future state of infrastructure as code testing.

1. Test Kitchen 1.0 A Config Management-Neutral Integration Testing Tool Fletcher Nichol October 26, 2013 DevOpsDays Vancouver 2013
2. I love big screens!
6. Ah.
7. Confidence
8. Test Kitchen
9. A test harness tool to execute your configured code on one or more platforms in isolation
10. Currently run Chef converges
11. Seeking input from other configuration management communities very soon
12. commit fda10bb71cc45c7eebeb4355f8dafa2b55f00709 Author: Fletcher Nichol <fnichol@nichol.ca> Date: Sat Dec 1 10:51:52 2012 -0700 Jamie: A Chef Convergence Integration Test Harness. Also, what the heck I am getting into here?
13. commit c8303426363a50a08137e518e124dad31facb9f1 Author: Fletcher Nichol <fnichol@nichol.ca> Date: Mon Jan 28 22:22:08 2013 -0700 Thank you Jamie, hello Test Kitchen. This is a first-pass renaming of the Jamie project to test-kitchen. The following are major breaking changes: * all constant references of `Jamie` have been renamed to `Kitchen` * the .jamie.yml file has been renamed to .kitchen.yml * the binary bin/jamie has been renamed to bin/kitchen * the Rake task namespace :jamie is now :kitchen * the Thor task namespace :jamie is now :kitchen * the `kitchen new_plugin` subcommand will create a 'kitchen-*' gem project
15. Happiness!
17. Goals
18. Simple workflow
19. Stressing speed
20. Optimizing for freshness of code & config
21. Declarative
22. Static configuration
23. Dead simple CI integration
24. $ bundle install $ rake kitchen:all
25. Testing freedom
26. Framework agnostic
27. Concurrent execution
28. Isolated log files
29. Virtualization freedom
30. Decoupled (plugin architecture)
31. Explicit vs. implicit
32. Ecosystem Demo Concepts
33. Ecosystem Demo Concepts
34. Test Kitchen runs suites on target platforms as instances using drivers
35. Platform
36. Operating system or target system Platform
37. Operating system version Platform
38. Hardware architecture, networking, virtualization, etc. Platform
39. It has a name Platform
40. Suite
41. Suite The Chef configuration
42. Suite A run list, node attributes
43. Suite It has a name
44. Instance
45. A suite + platform Instance
46. Name is auto-generated Instance
47. Has associated actions: create, converge, setup, verify, destroy Instance
48. Driver
49. An implementation of instance actions Driver
50. Packaged as a RubyGem Driver
51. One driver per instance Driver
52. Defines its own configuration requirements Driver
53. Bonus!
54. Test Kitchen runs suites on target platforms as instances using drivers and lets you optionally run tests on them to verify state
55. How?
56. Busser
57. “Your Mars Rover on a converged node” - me
58. “Your tests, your way!” - also me
59. Only dependency is Ruby (and thor gem)
60. Prepares node for test suites
61. Installs test runner plugins
62. busser-bash, busser-bats, busser-minitest, busser-shunit2, busser-aruba, busser- serverspec, busser-rspec, busser-shpec, busser-cucumber
63. No tests? No problem!
64. Ecosystem Demo Concepts
65. TK::Demorama.new.start!
66. Ecosystem Demo Concepts
67. Linting
68. Foodcritic
69. puppet-lint
70. Unit
71. ChefSpec
72. rspec-puppet
73. Integration
