SmartUI has introduced a feature that allows users to perform layout testing, which can help ensure web applications are free from layout inconsistencies. This feature uses the SmartUI SDK to capture and compare screenshots of web pages before and after code changes, highlighting pixel-level differences automatically. Layout testing in SmartUI focuses on testing the structure of web applications through DOM-based comparison, checking the DOM structure across different build versions to identify layout regressions. Unlike visual testing, layout testing analyzes the DOM structure and element relationships, ignoring content and style changes while focusing solely on structure, making it perfect for validating structural integrity and resilient to expected content variations.
