Continuous integration is a DevOps practice, where developers continuously integrate the code changes into a central repository. It most often refers to the build or the integration stage of the software release process. A continuous integration service helps to automatically build and run unit tests on the new code changes to find any errors instantly.

With an automated build which verified the code each time developers verify their changes into the version control repository. Which helps the development teams to detect any defect in an early stage. Continuous integration is the first part of CI/CD, which enables the development team to release the code changes gradually to production quickly and regularly.
