LambdaTest Visual Regression Testing is a SaaS platform that automates the process of detecting visual discrepancies in web and mobile applications. By comparing screenshots or DOM structures across builds, it ensures UI consistency and quickly highlights unintended changes. The platform leverages AI for smarter comparisons, supports integration with design tools like Figma, and enables visual validation for websites, apps, and PDFs. LambdaTest is designed for use by development and QA teams aiming to maintain a seamless user experience across different environments and releases.

Key Features

AI-Native Visual Comparison Automates detection of visual changes using advanced algorithms.

• Moves beyond basic pixel-to-pixel checks with AI-driven "Smart Ignore" to filter out layout noise and irrelevant shifts.
• Reduces false positives by ignoring dynamic or non-critical UI elements.

Cross-Platform and Multi-Device Support Validates UI consistency across browsers, devices, and platforms.

• Supports testing on real devices and browsers in the cloud.
• Enables bulk testing of static URLs and responsive layouts.

SmartUI Integration Directly compares design assets with live implementations.

• Figma-Web CLI allows side-by-side validation of Figma designs and live web pages.
• Supports configuration of specific Figma components for targeted validation.

PDF and App Visual Testing Ensures consistent rendering for non-web assets.

• Detects text, layout, and graphic differences in PDFs.
• Supports visual testing for mobile apps using real devices.

Advanced Region Selection and Annotation Focuses testing on critical UI areas.

• Annotate screenshots to define regions for inclusion or exclusion in comparisons.
• Bounding box support for targeted validation.

Baseline Management and Branching Manages visual baselines for different builds and branches.

• Smart Baseline Branching allows easy updates and comparisons across versions1.

Comprehensive Reporting and Integration Provides actionable insights and integrates with CI/CD pipelines.

• Generates detailed test reports and real-time notifications.
• Integrates with GitHub, Azure, Jenkins, and other tools for streamlined code reviews.
