THE PROBLEM

Ever worked on external managed infrastructure?

“The application stopped working all of a sudden”

“We didn't change anything!”

How can we validate external managed systems?

SERVERSPEC

Test servers actual state through SSH access

require 'spec_helper'

describe '<name of the resource>' do # your tests ...end

describe user 'daniel' do

it { should exist }

it { should belong_to_group 'sudo' }

it { should have_home '/home/daniel' }

end

describe package 'ntp' doit { should be_installed }

end

describe package 'chef' doit { should be_installed.by('gem') }

end

describe service 'ssh' doit { should be_enabled }

end

describe process 'sshd' doit { should be_running }

end

describe file '/etc/ssh/sshd_config' doits(:content) {

should match /^PermitEmptyPasswords\W+no$/

}end

describe file '~/.ssh/' doit { should be_directory }it { should be_mode 700 }

end

describe file '~/.ssh/authorized_keys' doit { should be_file }it { should be_mode 600 }it { should contain('daniel@inuits') }it { should be_owned_by 'daniel' }
