What ensures that automation runs as part of the delivery process?

The correctness of the choice revolves around the importance of having a defined set of tests in automation as a critical component of the delivery process. By establishing a framework of automated tests, developers ensure that each piece of code is systematically validated against defined requirements, catching any issues early in the development workflow. This not only helps maintain a high standard of software quality but also allows for faster feedback and deployment cycles.

Having a robust suite of automated tests is essential for continuous integration and delivery (CI/CD) pipelines, as they can be executed automatically as part of the deployment process to verify that new changes do not break existing functionality. This automated testing ensures that consistent and repeatable validation is performed on the software, ultimately leading to a more reliable release.

While some of the other options, such as regular code reviews or user acceptance testing, contribute to the overall quality assurance process, they do not inherently ensure that automation seamlessly integrates into the delivery workflow. Continuous monitoring plays a role in observing applications post-deployment, yet it operates separately from the proactive testing that happens before delivery. Thus, the presence of a clearly defined set of tests within an automation framework is paramount to ensuring that automation is a structured and reliable part of the delivery process.
