Serverspec

RSpec tests for your servers provisioned by Puppet, Chef and so on

Installation

Add this line to your application's Gemfile:

gem 'serverspec'

And then execute:

$ bundle

Or install it yourself as:

$ gem install serverspec

Usage

$ serverspec-init
 + spec/
 + spec/www.example.jp/
 + spec/www.example.jp/httpd_spec.rb
 + spec/spec_helper.rb
 + Rakefile

spec/www.example.jp/httpd_spec.rb is a sample spec file and its content is like this.

require 'spec_helper'

describe 'httpd', :os => :redhat do
  it { should be_installed }
  it { should be_enabled   }
  it { should be_running   }
end

describe 'port 80', :os => :redhat do
  it { should be_listening }
end

describe '/etc/httpd/conf/httpd.conf', :os => :redhat do
  it { should be_file }
  it { should contain "ServerName www.example.jp" }
end

You can write spec for testing provisioned servers like this.

You should create ~/.ssh/config like this before running tests.

Host *.example.jp
   User root
   IdentityFile ~/.ssh/id_rsa
   StrictHostKeyChecking no
   UserKnownHostsFile /dev/null

Run tests.

$ rake spec
/usr/bin/ruby -S rspec spec/www.example.jp/httpd_spec.rb

Multi OS support

Serverspec is supporting Red Hat based OS, Debian based OS, Gentoo and Solaris now.

If your target host's OS is Debian, you can write the spec like this.

require 'spec_helper'

describe 'httpd', :os => :debian do
  it { should be_installed }
  it { should be_enabled   }
  it { should be_running   }
end

describe 'port 80', :os => :debian do
  it { should be_listening }
end

describe '/etc/httpd/conf/httpd.conf', :os => :debian do
  it { should be_file }
  it { should contain "ServerName www.example.jp" }
end

Or like this.

require 'spec_helper'

describe 'www.example.jp', :os => :debian do
  it do
    'httpd'.should be_installed
  end

  it do
    'httpd'.should be_enabled
  end

  it do
    'httpd'.should be_running
  end

  it do
    'port 80'.should be_listening
  end

  conf = '/etc/httpd/conf/httpd.conf'

  it do
    conf.should be_file
  end

  it do
    conf.should contain "ServerName www.example.jp"
  end
end

Or modify spec/spec_helper.rb generated by serverspec-init command like this

require 'serverspec'
require 'pathname'

RSpec.configure do |c|
  c.include(Serverspec::DebianHelper)
  c.before do
    c.host = File.basename(Pathname.new(example.metadata[:location]).dirname)
  end
end

And write the spec like this.

require 'spec_helper'

describe 'httpd' do
  it { should be_installed }
  it { should be_enabled   }
  it { should be_running   }
end

describe 'port 80' do
  it { should be_listening }
end

describe '/etc/httpd/conf/httpd.conf' do
  it { should be_file }
  it { should contain "ServerName www.example.jp" }
end
