Continuous Integration

Constantly integrate new features

Advantages

• Tools => Jenkins, Travis, BuildBot, etc...
• Rapid retroaction => Easily see incompatibilities with new code. Immediately see breaking changes
• Can correct problems quickly
• To test into a control environment
• Automatic tests execution
• Keep a functional version at all times
• Make communication easy
• Minimal regression risks
• Rapidly identify problems
• Build and test on multiple environments
• Make people work on small tasks. Compartmentalization

Good Practices

• Automated build
• Automated tests upon build
• Commit often
• Always commit functional code
• Compilation and test time should be fast. Have nightly and daily build otherwise
• Environment should be as close as production as possible
• Automated deployment
• Results are seen by all team members
• Build failures must be a good thing. Not be afraid of it. Rejoice the bug has been found!
• Don't put too much emphasis on tendencies
• It can't always be green
• If it's red; keep calm, and correct it
• For big refactoring it takes time...
• Predict time to maintain integration system. It should be up to date
• It shouldn't use to blame others!
