12. require 'serverspec' 
 # RedHat 7 - 64bits:
 set :os, :family => 'redhat', :release => '7', :arch => 'x86_64'
 
 # Debian 7 - 32bits:
 set :os, :family => 'debian', :release => '7', :arch => 'i386'

 set :os, :family => 'ubuntu', :release => '14.04', :arch => 'x86_64' ...
13. para Rubistas <3 Alguns exemplos
14. # describe command com matchers: its(:stdout), its(:stderr), its(:exit_status) 
 # Apache2 + Passenger:
 describe command('apachectl -M') do
 its(:stdout) { should contain('mod_passenger') }
 end # nginx + Passenger:
 describe command('nginx -V') do
 its(:stdout) { should contain('--with-passenger') }
 end
15. # Vamos transformar em um shared behaviour: # Apache2 + Passenger:
 shared_examples 'apache2::passenger' do
 describe command('apachectl -M') do
 its(:stdout) { should contain('mod_passenger') }
 end end # nginx + Passenger: shared_examples 'nginx::passenger' do
 describe command('nginx -V') do
 its(:stdout) { should contain('--with-passenger') }
 end
 describe package('passenger') do
 it { should be_installed }
 end end
16. # utilizando em hosts distintos: describe 'myserver.com' do
 include_examples 'apache2::passenger' describe package('apache2') do it { should be_installed }
 end end describe 'myotherserver.com' do include_examples 'nginx::passenger' describe package('nginx-extras') do it { should be_installed }
 end end
