CI Fundamentals

What is CI?

• Source code management integration
• Removes repetitive, laborious actions
• Automated tests?
  • Sometimes
• Automated builds?
  • Fancy cron job, build scripts
• Automated deployments?
  • Seldom
• Standards / Conventions / Metrics
  • Coverage metrics
  • Code style, format
  • Development team metrics
• Something more ... ?

Continuous Integration

• Continuous = ALL THE TIME
• Integration = Combining the changes from all developers
• When should I check in?
  • As often as possible
  • Make “more often” more possible
• What should I do before I check in?
  • Shout out, have conversation – especially when you’ve just made cross-cutting or complex changes
  • Is it already broken?
  • Update from SCM repository
  • Pre-commit build
• How long should it take?
  • As quick as possible
  • Make “more quick” more possible
  • < 10 minutes (this is already painfully long)
