Unit Testing chef Cookbook

Chef Infra (archive)

Hi All,

I would like to know how to do unit testing of chef cookbooks. I have heard
about chefSpec but not very much familiar and used to …

My team had developed few cookbooks and would like to know the code
coverage, etc.

Any help would be highly appreciated.

Thanks & Regards,
Sachin Gupta

Hi,

sudo knife bootstrap --sudo -x -P -r “recipe [your_cookbook_name]”

above command will do bootstrap and it will install cookbook.

I wouldn’t necessarily call that testing, exactly, also, the sudo might be unnecessary in their environment (dangerous, even).

With regards to ChefSpec, that’s how we handle doing unit testing of our recipes. It’s fast (no convergence required), and lets you follow a TDD mentality (write your ChefSpec assertions first, then write your recipe).

On the other hand, integration tests are essential to determining that your cookbook actually did what you want it to do. For this, we utilize Test Kitchen, backed by either Vagrant or EC2, and Serverspec as our assertion library. This allows you to write tests, using Rspec syntax, that asset that the final result of your convergence has what you need (services are running, ports are being listened on, files exist & have certain content, etc.)

Between these two test libraries, we have grown in confidence regarding our cookbooks.

Thanks Jeff for sharing useful info.

I will work more on ChefSpec. do you have any documentation link for
chefSpec and Rspec.

Thanks & Regards,

Hi Sachin,

you might want to check out the "Test-driven Infrastructure with Chef
(2nd Edition)" book for a broad coverage of the topic:

It handles all things testing:

  • basic syntax checks via knife cookbook test
  • codestyle checks via foodcritic
  • unit testing via chefspec and fauxhai
  • integration testing via kitchen-ci and serverspec
  • plus some approaches on testing whole infrastructures (rather than
    single servers)
  • plus cookbook dependency management via berkshelf (vs. traditional
    monolithic chef repo style)

The code examples might be slightly out of date if you are
practicing them with the latest version of the tools (we live in a
fast evolving world ;-)), but conceptually things should be pretty
stable and if you stick with the versions mentioned in the book you
should be safe.

Sachin,

The best resource I have found for ChefSpec is the documentation on
GitHub. The Readme (GitHub - chefspec/chefspec: Write RSpec examples and generate coverage reports for Chef recipes!) gives a
fantastic overview, and the examples directory shows specific examples of
how to test individual resources (
https://github.com/sethvargo/chefspec/tree/master/examples). I refer to
the examples daily.

I’d back that the best ChefSpec resource is the GitHub README; also the issues & PRs offer valuable info as well.

Thanks Torben, Nolan and Jeff.

Currently I am referring GitHub documentation. I have few cookbooks (java,
weblogic, OHS) ready for unit testing.

Will share my findings with ChefSpec..
