Continuous integration (CI) is the concept of running tests and checks on each push, to reduce different risks related to the development cycle.

Motivation

• Be proactive rather than reactive
• Identify hotspots for refactoring efforts
• Reduce the risk of bugs and regressions

Goal: Code quality is not allowed to decrease.
