A Test Kitchen Provisioner for Ansible

The provider works by passing the ansible repository based on attributes in .kitchen.yml & calling ansible-playbook.

It install ansible on the server and runs ansible-playbook using host localhost.

Has been tested against the Ubuntu 1204 and Centos 6.5 boxes running in vagrant/virtualbox.

You'll need a driver box without a chef installation so ansible can be installed.

You'll need the test-kitchen & kitchen-ansible gem's installed in your system, along with kitchen-vagrant or some other suitable driver for test-kitchen.

Please see the Provisioner Options (https://github.com/neillturner/kitchen-ansible/blob/master/provisioner_options.md).

based on the example ansible setup for tomcat at https://github.com/ansible/ansible-examples/tree/master/tomcat-standalone

In the root directory for your Ansible role:

Create a .kitchen.yml, much like one the described above:

  ---
  driver:
    name: vagrant

  provisioner:
    name: ansible_playbook
    playbook: default.yml
    ansible_yum_repo: "https://download.fedoraproject.org/pub/epel/7/x86_64/e/epel-release-7-5.noarch.rpm"
    ansible_verbose: true
    ansible_verbosity: 3
    hosts: all

  platforms:
    - name: ubuntu-12.04
      driver_config:
        box: ubuntu/precise32
    - name: centos-7
      driver_config:
         box: chef/centos-7.0

  suites:
    - name: default

NOTE: With Test-Kitchen 1.4 you not longer need chef install to run the tests. You just need ruby installed version 1.9 or higher and also add to the .kitchen.yml file

  verifier:
    ruby_bindir: '/usr/bin'

where /usr/bin is the location of the ruby command.

Then for serverspec:

  mkdir -p test/integration/default/serverspec/localhost
  echo "require 'serverspec'" >> test/integration/default/serverspec/spec_helper.rb
  echo "set :backend, :exec" >> test/integration/default/serverspec/spec_helper.rb

Create a basic playbook test/integration/default.yml so that kitchen can use your role (this should include any dependencies for your role):

  ---
  - name: wrapper playbook for kitchen testing "my_role"
    hosts: localhost
    roles:
      - my_role

Create your serverspec tests in test/integration/default/serverspec/localhost/my_roles_spec.rb:

  require 'spec_helper'

  if os[:family] == 'ubuntu'
        describe '/etc/lsb-release' do
          it "exists" do
              expect(file('/etc/lsb-release').to be_file
          end
        end
  end

  if os[:family] == 'redhat'
    describe '/etc/redhat-release' do
      it "exists" do
          expect(file('/etc/redhat-release')).to be_file
      end
    end
  end

To test different playbooks in different suites you can easily overwrite the provisioner settings in each suite seperately.

  driver:
    name: vagrant

  provisioner:
    name: ansible_playbook

  platforms:
    - name: ubuntu-12.04
      driver_config:
        box: ubuntu/precise32
    - name: centos-7
      driver_config:
         box: chef/centos-7.0

  suites:
    - name: database
      provisioner:
        playbook: postgres.yml
        hosts: database
    - name: application
      provisioner:
        playbook: web_app.yml
        hosts: web_application

Notes

• The default in all of the above is the name of the test suite defined in the 'suites' section of your .kitchen.yml, so if you have more than suite of tests or change the name, you'll need to adapt my example accordingly.
• serverspec test files must be named _spec.rb
• Since I'm using Vagrant, my box definitions refer to Vagrant boxes, either standard, published boxes available from http://atlas.hashicorp.com/boxes or custom-created boxes (perhaps using Packer and bento), in which case you'll need to provide the url in box_url.
• This could be adapted to using Openstack/AWS/whatever VMs as supported by Vagrant.
