SmartUI has introduced a new feature for PDF testing, enhancing the visual regression testing platform by enabling users to ensure the quality and accuracy of PDF documents. This feature allows for detailed comparison of text, layout, graphics, and other elements within PDFs, generating comprehensive reports for discrepancies. Users can convert PDF pages into images with high precision, highlight mismatches, and define threshold settings for detecting differences. The platform supports parallel file processing, effectively reducing test execution time, and offers integration with popular version control systems for managing different PDF versions. With these capabilities, SmartUI aims to streamline the PDF testing process, making it more efficient and accurate for users, while providing a user-friendly interface and customization options.
