SmartUI: Visual Testing for Web and Mobile UIs

A visual testing tool captures and compares screenshots of your application's user interface against approved baselines to detect unintended visual changes. It identifies layout shifts, color mismatches, font inconsistencies, missing elements, and other visual defects that functional tests miss because the page technically works but looks wrong. Traditional visual testing tools use pixel-level comparison, which generates heavy false-positive noise from anti-aliasing and rendering differences. AI-native visual testing tools like SmartUI filter this noise automatically, surfacing only the changes that impact users.

Functional tests verify whether elements exist and behave correctly, but they do not validate how the UI actually looks. A button can pass every functional test while being completely hidden behind another element, and a CSS update can fix spacing on one viewport while breaking layout on three others. Visual testing tools catch these issues automatically by comparing screenshots across browsers, devices, and screen sizes. Without one, teams rely on manual screenshot comparison, which is slow, error-prone, and impractical at modern release velocity.

SmartUI captures baseline screenshots of your UI in its approved state. After code changes, it captures new screenshots and compares them with its Visual AI engine, which filters rendering noise, anti-aliasing artifacts, and dynamic content to flag only meaningful differences. Smart Ignore suppresses position shifts and dynamic regions, while Smart RCA pinpoints the root cause of each failure. Teams review highlighted changes in the SmartUI dashboard with side-by-side and overlay views, approve intentional changes as new baselines, and send regressions to developers. SmartUI integrates with Selenium, Cypress, Playwright, and Puppeteer for web, plus Appium, XCUITest, and Espresso for native mobile, and plugs into CI/CD pipelines to run visual tests automatically.

SmartUI detects layout shifts and broken alignments, CSS regressions like incorrect colors, fonts, padding, and margins, missing or overlapping elements, responsive design breakages across viewport sizes, cross-browser rendering inconsistencies between Chrome, Firefox, Edge, and Safari, image rendering issues, z-index and layering problems, text overflow or truncation, design drift from Figma specifications, and content changes in generated PDFs. Its Visual AI engine categorizes each change by severity from critical to low, helping teams prioritize fixes.

Yes. SmartUI supports automated PDF visual testing for generated invoices, contracts, reports, statements, and forms. The same AI engine that compares web pages detects text, layout, font substitution, and graphic differences across PDF versions, which is useful for teams in finance, insurance, and healthcare where document accuracy is critical.
