kitchen test

Now it’s time to introduce to the test meta-action which helps you automate all the previous actions so far into one command. Checking kitchen list, the “Last Action” of our instance should be “Verified”. With this in mind, let’s run kitchen test:

       You are installing a package without a version pin.  If you are installing
       on production servers via an automated process this is DANGEROUS and you will
       be upgraded without warning on new releases, even to new major releases.
       Letting the version float is only appropriate in desktop, test, development or
       CI/CD environments.

There’s only one remaining action left that needs a mention: the Destroy Action which as one might expect, destroys the instance. With this in mind, here’s what Test Kitchen is doing in the Test Action:

  1. Destroys the instance if it exists
  2. Creates the instance
  3. Converges the instance
  4. Verifies the instance with InSpec
  5. Destroys the instance

A few details with regards to test:

  • Test Kitchen will abort the run on the instance at the first sign of trouble. This means that if your Chef Infra Client run fails then Chef InSpec won’t be run and the instance won’t be destroyed. This gives you a chance to inspect the state of the instance and fix any issues.
  • The behavior of the final destroy action can be overridden if desired. Check out the CLI help for the --destroy flag using kitchen help test.
  • The primary use case in mind for this meta-action is in a Continuous Integration environment or a command for developers to run before check in or after a fresh clone. If you’re using this in your test-code-verify development cycle it’s going to quickly become very slow and frustrating. You’re better off running the converge and verify sub-commands in development and save the test sub-command when you need to verify the end-to-end run of your code.

Finally, let’s check the status of the instance:

$ kitchen list
Instance             Driver   Provisioner  Verifier  Transport  Last Action    Last Error
default-ubuntu-2004  Vagrant  ChefInfra     Inspec    Ssh        <Not Created>  <None>

Back to square one.
