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 don’t 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....

Why should you Automate it?

Enhanced Cooperation: By offering a common framework for evaluating and verifying UI modifications, automated visual regression testing fosters cooperation across developers, designers, and QA engineers. Consistency: Visual regression tests are performed consistently across various browsers, devices, and environments thanks to automation, which produces more dependable and repeatable results. Early Issue Detection: Teams can identify and resolve visual inconsistencies early in the development process, preventing them from developing into more serious issues, by including visual regression testing into the CI/CD pipeline. Efficiency: Teams may test more frequently and thoroughly due to automation, which drastically cuts down on the time and effort needed to do visual regression testing as compared to human techniques. Accuracy: Automated tools can take and compare screenshots with precision, reducing the possibility of human error in manual testing and guaranteeing accurate results. Better User Experience: Automation contributes to the upkeep of a polished and consistent user interface by proactively detecting and fixing visual flaws, which eventually improves user happiness and experience in general....

What about Manual Visual Checks?

Manual visual checks include human testers visually examining a web application’s user interface to find any errors, inconsistencies, or variations. Although automation has many benefits, manual visual checks have a role in the testing process and offer certain advantages of their own....

What percentage of Visual Bugs are caught by Automated Visual Regression Tests?

Although a large percentage of visual flaws can be detected by automated visual regression tests, the precise percentage depends on test design, UI complexity, and the tools and techniques used. To obtain complete test coverage and guarantee a superior user experience, it is frequently required to combine automated testing with manual verification and exploratory testing....
