Which of the following is a benefit of visual testing?

Visual testing plays a crucial role in ensuring consistency and accuracy in the presentation of web applications. The identified benefit, which is the ability to detect visual discrepancies after code changes, is particularly significant because even minor alterations in code can lead to unintended visual changes. This includes issues such as misaligned elements, incorrect color schemes, and proportions being altered, which can negatively impact user experience.

By employing visual testing, teams can automatically capture screenshots of the application before and after changes are made, allowing them to compare these visuals using various techniques like pixel-by-pixel comparison. This methodology not only identifies discrepancies quickly but also helps maintain a consistent visual appearance across different devices and browsers. Consequently, it fosters a higher level of confidence in the quality of the release, enhances user satisfaction, and reduces the likelihood of negative user feedback related to design flaws.

Other options either address areas not specifically covered by visual testing or suggest guarantees that are not achievable through testing alone. For instance, ensuring all browser types load simultaneously or creating only mobile-friendly designs doesn't directly relate to the primary function of visual testing, which is focused on identifying visual differences rather than performance or design principles. Moreover, focusing solely on functionality disregards the importance of visual aspects, which are key to user interface integrity and user
