Summary

Looking at the evolutionary history of the software engineering process, we now know how Continuous Integration came into existence. Truly, Continuous Integration is a process that helps software projects go agile.

The various concepts, terminologies, and best practices discussed in this chapter form a foundation for the upcoming chapters. Without these, the upcoming chapters are mere technical know-how.

In this chapter, we also learned how various DevOps tools go hand-in-hand to achieve Continuous Integration, and of course, help projects go agile. We can fairly conclude that Continuous Integration is an engineering practice where each chunk of code is immediately built and unit-tested, then integrated and again built and tested on the Integration branch.

We also learned how feedback forms an important part of a Continuous Integration system.

Continuous Integration depends incredibly on automation of various software development processes. This also means that using a Continuous Integration tool alone doesn't help in achieving Continuous Integration, and Continuous Integration does not guarantee zero bugs. But it guarantees early detection.
