Test-driven Development for Operations Engineers

In this talk, Kerim Satirli (@ksatirli) and I look at how we apply a test-driven approach towards operations engineering.

We look at the testing for operations engineers, what RSpec is and how to make Packer and Docker images testable.

This version of the talk was given at CfgMgmtCamp 2017 in Ghent, Belgium.

1. Test-driven development for Operations Engineers
2. Thomas Krag Infrastructure Engineer, EclecticIQ
3. Kerim Satirli Infrastructure Engineer, OlinData
4. Test-driven development A history lesson
6. We need to be safe to experiment and make mistakes. We feel good when things work smoothly.
7. We need testing to be sure we are doing no harm. - Kent Beck
8. Trust, but verify.
9. Test-driven development For Software Engineers
13. Test-driven development For Operations Engineers
19. RSpec Test Structure
20. describe 'section' do describe target('selector') do it { should have_something } it { should be_something } end end
21. describe 'YUM repositories' do describe yumrepo('epel') do it { should exist } it { should be_enabled } end end
