What is screenshot testing?

Screenshot testing is a technique that verifies that your application is working as expected by capturing an image of the application's output and comparing it with an expected result. With LambdaTest's screenshot comparison tool, you can capture screenshots in bulk through different desktops and mobile devices running on various OSs. This is made possible by instrumented UI test cases that help you see how your web app renders across various screen sizes using different browsers.
