Visual testing is crucial for maintaining which aspect of a software product?

Visual testing plays a vital role in ensuring visual consistency within a software product. This practice focuses on validating the UI components of an application, confirming that they render correctly across various devices, screen sizes, and browsers. By maintaining visual consistency, visual testing helps ensure that users experience a cohesive look and feel, allowing for intuitive navigation and interaction. In contrast, aspects like financial accuracy, backend efficiency, and database reliability pertain to different domains of software quality, such as functionality, performance, and data integrity, which are not directly related to the visual presentation of the user interface.
