What does Visual Regression Testing Mean?
Visual regression testing is a software development technique for identifying unintentional visual modifications made to the user interface (UI) of a web application. To find any differences, screenshots of the user interface (UI) of the application are compared before and after code changes. Developers can guarantee that changes to the coding donât bring about unexpected visual changes that could degrade the user experience by automating this process. Visual regression testing contributes to the overall quality and usability of the program by ensuring that it looks consistent across a range of browsers, devices, and screen resolutions.
Purpose of Visual Regression Testing:
- Detecting Visual Defects: VRT aims to identify any visual discrepancies or defects introduced during the development process, such as layout shifts, color changes, font variations, or UI element misalignments.
- Maintaining Visual Consistency: It helps maintain a consistent and polished user experience by ensuring that UI elements render correctly across various devices, browsers, and screen resolutions.
- Preventing User Experience Issues: By catching visual bugs early, VRT reduces the risk of user-facing issues that could impact usability, accessibility, and overall customer satisfaction.
How to Automate Visual Regression Testing?
Automation is essential to simplifying this process since it provides the testing workflow with efficiency, accuracy, and scalability. Development teams can identify visual differences early in the development cycle by automating visual regression testing. This allows for quick feedback and improves the overall quality of the software. Letâs understand about this term in detail.
