Quick Installation

Add this line to your application's Gemfile:

gem 'serverspec'

And then execute:

Or install it yourself as:

Usage

$ serverspec-init
Select OS type:

  1) UN*X
  2) Windows

Select number: 1

Select a backend type:

  1) SSH
  2) Exec (local)

Select number: 1

Vagrant instance y/n: n
Input target host name: www.example.jp

 + 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 package('httpd') do
  it { should be_installed }
end

describe service('httpd') do
  it { should be_enabled }
  it { should be_running }
end

describe port(80) do
  it { should be_listening }
end

describe file('/etc/httpd/conf/httpd.conf') do
  it { should be_file }
  its(:content) { should match /ServerName www.example.jp/ }
end

You can write specs for testing servers like this.

Serverspec with SSH backend logs in to target servers as a user configured in ~/.ssh/config or a current user. If you'd like to change the user, please edit the below line in spec/spec_helper.rb.

user = options[:user] || Etc.getlogin

Run tests.

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

Multi OS support

Serverspec supports Darwin based OS, Red Hat based OS, Debian based OS, Gentoo, Solaris and Arch.

Serverspec can detect target host's OS automatically.

If you'd like to set target host's OS explicitly, you should include SpecInfra::Helper::OSName in spec/spec_helper.rb like this.

require 'serverspec'
require 'pathname'
require 'net/ssh'

include SpecInfra::Helper::Ssh
include SpecInfra::Helper::Debian

RSpec.configure do |c|
  # Add SSH before hook in case you use the SSH backend
  # (not required for the Exec backend)
  c.before do
    host  = File.basename(Pathname.new(example.metadata[:location]).dirname)
    if c.host != host
      c.ssh.close if c.ssh
      c.host  = host
      options = Net::SSH::Config.for(c.host)
      user    = options[:user] || Etc.getlogin
      c.ssh   = Net::SSH.start(c.host, user, options)
    end
  end
end

You can select from:

• SpecInfra::Helper::RedHat
• SpecInfra::Helper::Debian
• SpecInfra::Helper::Fedora
• SpecInfra::Helper::Gentoo
• SpecInfra::Helper::Solaris
• SpecInfra::Helper::Darwin
• SpecInfra::Helper::Arch

Vagrant support

Serverspec now has Vagrant support, and can be automatically configured from a Vagrantfile.

$ serverspec-init

  1) SSH
  2) Exec (local)
