TESTING doc

This Cookbook has a dependency. It requires the vSphere Automation SDK be installed. The steps to do that are as follows, for the time being it's not published to Rubygems, if you are interested please comment here.

Bundler

A ruby environment with Bundler installed is a prerequisite for using the testing harness shipped with this cookbook. At the time of this writing, it works with Ruby 2.0 and Bundler 1.5.3. All programs involved, with the exception of Vagrant, can be installed by cd'ing into the parent directory of this cookbook and running "bundle install"

Rakefile

The Rakefile ships with a number of tasks, each of which can be ran individually, or in groups. Typing "rake" by itself will perform style checks with Rubocop and Foodcritic, ChefSpec with rspec, and integration with Test Kitchen using the Vagrant driver by default.Alternatively, integration tests can be ran with Test Kitchen cloud drivers.

$ rake -T
rake integration:cloud    # Run Test Kitchen with cloud plugins
rake integration:vagrant  # Run Test Kitchen with Vagrant
rake spec                 # Run ChefSpec examples
rake style                # Run all style checks
rake style:chef           # Lint Chef cookbooks
rake style:ruby           # Run Ruby style checks
rake travis               # Run all tests on Travis

Style Testing

Ruby style tests can be performed by Rubocop by issuing either

bundle exec rubocop

or

rake style:ruby

Chef style tests can be performed with Foodcritic by issuing either

bundle exec foodcritic

or

rake style:chef

Spec Testing

Unit testing is done by running Rspec examples. Rspec will test any libraries, then test recipes using ChefSpec. This works by compiling a recipe (but not converging it), and allowing the user to make assertions about the resource_collection.

Integration Testing

Integration testing is performed by Test Kitchen. Test Kitchen will use either the Vagrant driver or various cloud drivers to instantiate machines and apply cookbooks. After a successful converge, tests are uploaded and ran out of band of Chef. Tests should be designed to ensure that a recipe has accomplished its goal.

Integration Testing using Vagrant

Integration tests can be performed on a local workstation using Virtualbox or VMWare. Detailed instructions for setting this up can be found at the Bento project web site.

Integration tests using Vagrant can be performed with either

bundle exec kitchen test

or

rake integration:vagrant

Integration Testing using Cloud providers

Integration tests can be performed on cloud providers using Test Kitchen plugins. This cookbook ships a .kitchen.cloud.yml that references environmental variables present in the shell that kitchen test is ran from. These usually contain authentication tokens for driving IaaS APIs, as well as the paths to ssh private keys needed for Test Kitchen log into them after they've been created.

Examples of environment variables being set in ~/.bash_profile:

# digital_ocean
export DIGITAL_OCEAN_CLIENT_ID='your_bits_here'
export DIGITAL_OCEAN_API_KEY='your_bits_here'
export DIGITAL_OCEAN_SSH_KEY_IDS='your_bits_here'

# aws
export AWS_ACCESS_KEY_ID='your_bits_here'
export AWS_SECRET_ACCESS_KEY='your_bits_here'
export AWS_KEYPAIR_NAME='your_bits_here'

# joyent
export SDC_CLI_ACCOUNT='your_bits_here'
export SDC_CLI_IDENTITY='your_bits_here'
export SDC_CLI_KEY_ID='your_bits_here'

Integration tests using cloud drivers can be performed with either

export KITCHEN_YAML=.kitchen.cloud.yml
bundle exec kitchen test

or

rake integration:cloud
