In this talk I show a usecase to use ServerSpec to test external managed systems with ease.

1. Continuous
Infrastructure
Testing

2. WHOAMI

3. class daniël {
class {'::work':
company => 'Inuits',
location => 'Rotterdam',
role => 'Open Source Consultant',
contact => 'daniel@inuits.eu',
}
class {'::social':
twitter => '@dpnl87',
github => 'dpnl87',
blog => 'danielpaulus.com',
}
}

4. THE PROBLEM

5. Ever worked on external
managed infrastructure?

6. “The application stopped
working all of a sudden”

7. “We didn't
change anything!”

8. How can we validate external
managed systems?

9. SERVERSPEC

10. Test servers actual state
through SSH access

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

12. describe user 'daniel' do
it { should exist }
it { should belong_to_group 'sudo' }
it { should have_home '/home/daniel' }
end

13. describe package 'ntp' do
it { should be_installed }
end
describe package 'chef' do
it { should be_installed.by('gem') }
end

14. describe service 'ssh' do
it { should be_enabled }
end
describe process 'sshd' do
it { should be_running }
end
describe file '/etc/ssh/sshd_config' do
its(:content) {
should match
/^PermitEmptyPasswordsW+no$/
}
end

15. describe file '~/.ssh/' do
it { should be_directory }
it { should be_mode 700 }
end
describe file '~/.ssh/authorized_keys' do
it { should be_file }
it { should be_mode 600 }
it { should contain('daniel@inuits') }
it { should be_owned_by 'daniel' }
end
