Sauce Labs recently acquired Screener, a developer tool that helps teams create automated visual tests for their applications. Visual testing is crucial to catch unintended visual bugs when updating UI components and verifies that the UI appears correctly from the user's perspective. It differs from functional testing, which covers all workflows of the system by fully exercising the GUI itself. As development teams shift focus to automated testing, it's essential to include both functional and visual testing in their strategy to ensure a seamless user experience across various devices and screen resolutions. With numerous visual testing frameworks available, such as Applitools, DPXDT, and BackstopJS, teams can choose one that fits their needs to satisfy their missing visual test coverage.
