Continuous integration involves integrating code changes frequently, usually daily, and automatically verifying the integrated code through builds and tests to detect errors early. It helps development teams improve efficiency by catching issues as soon as possible. Common tools for continuous integration include Hudson/Jenkins for running builds and tests, Sonar for code quality checks, and Nexus for artifact management. Continuous delivery takes continuous integration further by ensuring code is always in a releasable state.

4. Continuous integration Continuous Integration is a software development practice where members of a team integrate their work frequently , usually each person integrates at least daily - leading to multiple integrations per day. Each integration is verified by an automated build (including test) to detect integration errors as quickly as possible .
