The aspect of testing the visuals is a key element of software testing which involves the verification of the graphical user interface of an application. Different from the conventional testing methods that predominantly focus on functionality, visual testing verifies that the application’s visual elements like layout, design, and appearance are in line with the specified criteria and expectations. This article is going to take us through the basics of visual testing, why it is important in software development, and best practices for visual testing implementation.
The Importance of Visual Testing
In the present digital era where competitiveness is at its peak, user experience (UX) is considered as one of the decisive factors of the success of software applications. An eye-catching and user-friendly UI can greatly influence user satisfaction and retention. Issues related to the visuals, such as elements that are not aligned correctly or inconsistent styling, may degrade the user experience and undermine the credibility of the application. Visual testing is a tool that spots visual inconsistencies and fixes them compared to manual testing, which helps to avoid undesired UI situations during the development process.
What is Visual Testing?
Visual testing is the process of comparing the visual output of an application with a collection of visual reference images to tell whether there are any differences or errors. It checks that UI elements, that is fonts, colours, images, and alignment, behave uniformly among the different browsers, devices, and screen resolutions. Visual testing is a complement to functional testing but with a difference in that, it looks at the user's impression of the application's appearance and usability.
Implementing Visual Testing
To implement visual testing effectively, consider the following best practices:
Now you know what is visual testing, its importance cannot be undermined. With visual defects and inconsistency detection in the early design stage, visual testing ensures decode polished and consistent user experience. Following the best practices and utilizing suitable tools, organizations can make visual testing part of their testing processes, guaranteeing faster-quality software and user satisfaction.
