Visual Testing With SmartUI's Visual AI Engine

Visual AI in test automation pinpoints the root cause of issues, directing developers to the exact code that needs fixing.

Beyond the traditional pixel comparison method, SmartUI also offers two advanced AI-driven image comparison approaches: Smart Ignore and Layout based analysis. The Layout type uses AI to identify and align distinct zones between the checkpoint image and the baseline image, making it easy to pinpoint layout changes with precision. The Smart Ignore diff type ignores minor shifts like slight button displacements or layout alignment adjustments. The highlighted areas are, therefore, much more refined, with fewer irrelevant changes being flagged.

With the help of LambdaTest you can incorporate visual regression testing in your existing CI/CD pipeline. It not only saves time but ensure the detection of any possible human error. LambdaTest will generate the report with differences between screenshots taken before and after the code changes.

Visual regression testing is crucial for identifying visual defects such as incorrect styles, misalignments, and font issues. It helps detect common problems like overlapping modules, hidden or missing elements, and elements that render off-screen, ensuring your application maintains a consistent and polished appearance.

Visual regression testing tools capture screenshots of web pages and perform pixel-by-pixel comparisons of these images. In snapshot testing, values are serialized and saved in text files, which are then compared using a diff algorithm to identify any discrepancies.

Visual Regression Testing (VRT) is a software testing technique that compares screenshots of a user interface before and after changes to the application.
