What is the significance of maintaining design mockups throughout the testing process?

Maintaining design mockups throughout the testing process is crucial because they serve as consistent reference points for visual standards. This ensures that all stakeholders, including developers, designers, and quality assurance teams, are aligned on the intended design and user experience. By referring back to these mockups, teams can verify that the final product adheres to the established visual specifications, helping to maintain brand identity and user interface consistency. This reference also aids in identifying discrepancies early in the testing process, allowing for timely corrections and enhancing overall product quality before launch.
