Continuous Integration
Integrate code often and test automatically.
📖 Key ideas
- CI: developers merge small changes to the main branch frequently.
- Every push triggers an automated build and tests.
- Failing builds are fixed immediately.
- Tools: GitHub Actions, GitLab CI, Jenkins, CircleCI.
- Fast feedback keeps the main branch healthy.
💡 Real-life example: CI is a quality checkpoint at the factory gate: every new part is tested before joining the assembly.
