Continuous Integration (CI) is the practice of merging all developer working copies to a shared mainline several times a day. Each integration is verified by an automated build and test process, which helps detect integration issues early and ensures that the codebase remains stable. CI encourages frequent commits to the shared repository, enabling teams to identify and resolve conflicts and errors promptly. By automating the build and test process, CI improves code quality, accelerates development cycles, and facilitates collaboration among developers. Implementing CI can lead to more cohesive and manageable codebases, reducing the likelihood of integration problems and enhancing overall team productivity.
