CI is a development practice that helps to prevent potential integration issues. Software integration issues refer to the difficulties that may arise during the practice of combining individually tested software components into an integrated whole. Software is integrated when components are combined into subsystems or when subsystems are combined into products.
Components may be integrated after all are implemented and tested, as in a waterfall model or a big bang approach. On the other hand, CI requires developers to daily commit their code into a remote code repository. Each commit is then verified by an automated process, allowing teams to detect integration issues earlier.
In this chapter, we have learned how to create a code repository on GitHub and how to validate our application using unit tests and linting tools, but we haven't configured...
