Continuous Integration (CI) Explained
Continuous Integration, or CI, is the practice of merging every developer's work into a shared codebase frequently — often several times a day — and automatically checking it each time.
The goal is to catch conflicts and mistakes while they are small, rather than discovering a tangle of problems weeks later when everyone tries to combine their work at once.
How CI Works in Practice
- A developer pushes their change to the shared repository.
- An automated server builds the application from scratch.
- The full test suite runs against the new build.
- If anything fails, the team is alerted within minutes.
- Only passing changes are allowed to move toward release.
Why It Matters to You
CI keeps the codebase in a known-good state at all times. That means new features can be added steadily without the project grinding to a halt during a painful “big merge”, and it dramatically reduces the risk of broken code reaching your customers.
Frequently Asked Questions
How often does integration happen?
Ideally many times a day. Small, frequent merges are far safer than large, infrequent ones.
What happens if a check fails?
The change is held back and the developer fixes it before it can progress, so problems never accumulate.
