What principle encourages developers to commit and test updates frequently, sometimes multiple times a day?

The principle that encourages developers to commit and test updates frequently, often multiple times a day, is continuous integration. This practice involves automatically testing code changes to identify issues early in the development process, ensuring that the codebase remains stable and functional as new updates are made.

By integrating code changes into a shared repository multiple times each day, developers can address issues immediately, leading to a more efficient development process. This reduces integration problems and allows teams to deliver high-quality software more consistently. Continuous integration is crucial for maintaining the rhythm of development and ensuring that all team members are working with the most current version of the codebase.

Continuous delivery and continuous deployment are related concepts but focus more on the processes following integration. Continuous delivery prepares the integrated code for release to production, while continuous deployment automates the release process. Continuous monitoring involves tracking system performance and security but does not specifically address the frequency of code commits and tests in the development workflow.
