ansible_spec_plus

ansible_spec_plus

Tests Ansible roles, hosts and playbooks separately with Serverspec. Provides test coverage. Supports local and remote test execution.

This is a Ruby gem that uses the Ansible Config Parser for Serverspec connector and extends it to be able to run tests for roles, hosts or playbooks separately.

Features

• Supports all features of ansible_spec
• Supports listing of available tests
• Supports separate test execution of role tests
• Supports separate test execution of host tests
• Supports separate test execution of playbook tests (playbook tests combine role and hosts tests)
• Supports resource code/test coverage
• Supports remote (default) and local test execution (on a Vagrant box for example) by a command switch
• Currently supported Ansible resources:
  • file
  • template
  • docker_container
  • docker_image
  • service
  • apt
  • pip
  • gem

Installation

$ gem install ansible_spec_plus

Usage

Create necessary files

$ asp-init
    create  spec
    create  spec/spec_helper.rb
    create  .ansiblespec
    create  .rspec

[Optional] site.yml

This files describes the master playbook and includes all your custom playbooks. Ansible Spec plus relies on all entries when it comes to playbooks. If you ever create a playbook, make sure to add it into site.yml, too.

- include: demo.yml
- include: another-playbook.yml

[Optional] .ansiblespec

By default, site.yml will be used as the playbook and hosts as the inventory file. You can either follow these conventions or you can customize the playbook and inventory using an .ansiblespec file.

---
-
  playbook: site.yml
  inventory: hosts
  hash_behaviour: merge

[Optional] .rspec

Test coverage calculation rested on RSpec's JSON report.

--color
--format documentation
--format json --out report.json

Inventory

All inventory files from ansible_spec are supported as well as Vagrant-style inventory files like this:

# Generated by Vagrant

dev ansible_ssh_host=127.0.0.1 ansible_ssh_port=2222 ansible_ssh_private_key_file=private_key ansible_ssh_user=vagrant

These Vagrant-style inventories will be created by Vagrant's VAI plugin. No need to add this to version control. Install the VAI plugin with vagrant plugin install vai and add this section to your Vagrantfile:

config.vm.provision :vai do |ansible|
  ansible.inventory_dir = './'
  ansible.inventory_filename = 'hosts'
end

Writing tests

You can write tests for roles and/or hosts. Create a *_spec.rb file at the proper place (see below). Require your spec_helper to include all needed logic and start writing your specs. Use all resource types described at the Serverspec documentation.

Running tests

Role tests

Role tests can be found under roles/<name of your role>/spec/*_spec.rb. Execute tests by simply typing

asp rolespec <name of your role>

or - for local test execution on a Vagrant box -

asp rolespec <name of your role> -l

Host tests

Host tests can be found under spec/<name of your host>/*_spec.rb. Execute tests by simply typing

asp hostspec <name of your host>

or - for local test execution on a Vagrant box -

asp hostspec <name of your host> -l

Playbook tests

Host tests combine role and host tests for a given playbook. Execute tests by simply typing

asp playbookspec <name of your playbook>

or - for local test execution on a Vagrant box -

asp playbookspec <name of your playbook> -l

1. Create the test code that verifies our future Ansible implementation:

require 'spec_helper'

describe package('python-pip') do
  it { should be_installed.by('apt') }
end

1. Run the test and see it fail:

asp rolespec docker

Package "docker-engine"
  should be installed by "apt"

Package "python-pip"
  should be installed by "apt" (FAILED - 1)

Failures:

  1) Package "python-pip" should be installed by "apt"
     On host `127.0.0.1'
     Failure/Error: it { should be_installed.by('apt') }
       expected Package "python-pip" to be installed by "apt"
       sudo -p 'Password: ' /bin/sh -c dpkg-query\ -f\ \'\$\{Status\}\'\ -W\ python-pip\ \|\ grep\ -E\ \'\^\(install\|hold\)\ ok\ installed\$\'

     # ./roles/docker/spec/main_spec.rb:8:in `block (2 levels) in <top (required)>'

Finished in 0.56807 seconds (files took 1.02 seconds to load)
2 examples, 1 failure

Failed examples:

rspec ./roles/docker/spec/main_spec.rb:8 # Package "python-pip" should be installed by "apt"

1. Implement the Ansible feature and provision your system:

- name: Debian python-pip is present
  apt:
    name: python-pip
    state: present
    force: yes

vagrant provision demo

1. Run the test again and see it pass:

asp rolespec docker

Package "docker-engine"
  should be installed by "apt"

Package "python-pip"
  should be installed by "apt"
