What is a necessary element of the application structure during design?

During the design phase of an application, having an organization for automated testing is a vital element of the application structure. This approach not only enhances the quality of the application but also ensures that changes and new features can be integrated and tested quickly and reliably. Automated testing allows for continuous integration and delivery, enabling teams to detect issues early in the development process and maintain the integrity of the application's functionality over time.

By incorporating a well-structured automated testing strategy, teams can improve efficiency, reduce manual testing efforts, and ultimately deliver a more robust product. This organization helps facilitate consistent testing of various components, aligns with agile methodologies, and supports the overall goal of delivering high-quality applications.

In contrast, while other elements such as user feedback, mobile compatibility, and integration with social media are important to consider, they do not directly impact the underlying structure of the application in the same way that a focus on automated testing does during the design phase.
