Foodtaster

Gem Version

Foodtaster is a library for testing your Chef code with RSpec. Specs are actually executed on VirtualBox machine(s) managed by Vagrant.

Foodtaster uses VM snapshots to bring something like DB transactions into your cookbook specs. Before each Chef Run VM is rolled-back into initial 'clean' state which removes any modifications made by previously executed specs. It allows you to independently test different cookbooks on a single VM.

You aren't limited by just one VM for your specs, you may run as many as you need. PostgreSQL replication, load balancing and even entire application environments becomes testable (of course, if you have enought amount of RAM for all your VMs).

Check out foodtaster-example repository to see Foodtaster in action.

Foodtaster is on early development stage, so feedback is very appreciated.

Quick Example

require 'spec_helper'

describe "nginx::default" do
  run_chef_on :vm0 do |c|
    c.json = {}
    c.add_recipe 'nginx'
  end

  it "should install nginx as a daemon" do
    vm0.should have_package 'nginx'
    vm0.should have_user('www-data').in_group('www-data')
    vm0.should have_running_process('nginx')
    vm0.should listen_port(80)

    vm0.should have_file("/etc/nginx/nginx.conf")
      .with_content(/gzip on/)
      .with_mode(0644)
  end

  it "should have valid nginx config" do
    result = vm0.execute("nginx -t")

    result.should be_successful
    result.stdout.should include("/etc/nginx/nginx.conf syntax is ok")
  end
end

Installation

First, install VirtualBox and Vagrant. Then install vagrant-foodtaster-server plugin:

vagrant plugin install vagrant-foodtaster-server

Usage

In your Chef or Cookbook repository, create a basic Gemfile:

source 'https://rubygems.org/'

gem 'foodtaster'

Create a Vagrantfile describing VMs you need for specs. Read Wiki for detailed explanation and examples.

Create spec folder with basic spec_helper.rb file:

require 'foodtaster'

You are now ready to write cookbook specs. Run them as usual with command:

bundle exec rspec spec
