What is Continuous Integration?
• Continuous Integration is a software development practice
where members of a team integrate their work frequently.
• Each integration is verified by an automated build (including
test) to detect integration errors as quickly as possible.
• When CI works well, it helps the code stay robust enough that
customers and other stakeholders can play with the code
whenever they like.
• Like refactoring, continuous integration works well if you have
an exhaustive suite of automated unit tests that ensure that you
are not committing buggy code.

PRACTICES OF CONTINUOUS INTEGRATION
Maintain a Single Source Repository
Automate the Build
Make Your Build Self-Testing
Everyone Commits To the Mainline Every Day
Every Commit Should Build the Mainline on an Integration
Machine
Keep the Build Fast
Test in a Clone of the Production Environment
Make it Easy for Anyone to Get the Latest Executable
Everyone can see what's happening
Automate Deployment
