ITGSS Certified DevOps Engineer Practice Test

What practice automatically builds and tests code changes when a developer checks in their code?

1. Continuous Delivery

2. Continuous Integration

3. Version Control

4. Application Deployment

The correct answer is: Continuous Integration

The correct choice pertains to the practice known as Continuous Integration. This methodology focuses on the automation of code integration from multiple contributors into a shared repository. When developers check in their code, an automated process triggers the building and testing of that code. This practice ensures that code changes are regularly validated, catching errors early in the development cycle and preventing integration conflicts later on. Continuous Integration emphasizes the importance of frequent code commits, encouraging developers to integrate their changes into a central repository multiple times a day. This not only speeds up the overall development process but also improves collaboration among team members, as everyone is aware of changes being made in real-time. For clarity, Continuous Delivery, while related, refers to the subsequent phase where the integrated code is automatically prepared for release to production, but it does not specifically focus on the immediate testing and building of code changes. Version Control is a system that manages changes to source code but does not inherently involve automated testing or builds. Application Deployment, on the other hand, pertains to the process of releasing the application to users, which occurs after ensuring the code is built and integrated successfully.
