How is visual testing integrated into Agile methodologies?

Visual testing is integrated into Agile methodologies by incorporating it into iterative development cycles. This approach aligns with Agile principles, where development is broken down into manageable iterations or sprints. Within each sprint, teams are encouraged to continuously test and provide feedback on the product, ensuring that visual elements meet quality standards and user experience expectations.

By integrating visual testing throughout these iterative cycles, teams can catch visual defects early and iterate on designs based on real-time feedback. This leads to improved collaboration among team members, allows for quicker adjustments to be made based on testing results, and ultimately fosters a more dynamic and flexible development environment that can adapt to changes in requirements or design preferences.

In contrast to the other options, using a waterfall approach does not effectively support the Agile methodology's emphasis on flexibility and iterative progress. Running visual tests solely at the end of the project could lead to discovering major defects late in the process, which is counterproductive in Agile. Lastly, completely eliminating visual testing contradicts the foundational principles of Agile, where user experience and quality assurance are critical to the development process.
