Continuous Integration

Opi Danihelka

Continuous Integration (CI) is the process of automating the build and testing of code every time a team member commits changes to version control.

Continuous Integration

• Rapid feedback and defects detection
• Prevents integration problems (merge conflicts, deployment issues)
• Multiple releases per day
• Continuous Delivery / Continuous Deployment
• "DevOps" role

• Keep master branch clean (Gitflow)
• Automate the build
• Build is self testing
• Build every PR
• Keep the build fast
• Test in clone of production environment
• Everyone can see build result
• Automated Deployment
