Continuous integration is a software development practice where developers regularly merge their code changes into a central repository, after which automated builds and tests are run.
With continuous integration, developers frequently commit to a shared repository using a version control system such as Git. Prior to each commit, developers may choose to run local unit tests on their code as an extra verification layer before integrating.
