Toward the end of this chapter, we will learn how to configure a CI service. The CI service will observe changes in our application's code and ensure that the changes don't break the application.
To be able to observe the changes in the code, we will need to use a source control system. There are a few source control systems available. Some of the most widely used ones are Subversion, Mercurial, and Git.
Source control systems have many benefits, among which we can highlight the following:
- Source control tools enable multiple developers to work on a source file without any work being potentially lost by one developer overriding previous changes.
- Source control tools allow us to track and audit the changes in our source code. ...
