What This Skill Does

Generates SmartUI visual regression test configurations that capture page screenshots and compare them against baselines on LambdaTest's cloud. Works with Playwright, Selenium, Cypress, and Puppeteer. Diffs show up in the SmartUI dashboard for review and approval.

Instead of eyeballing pages after every deploy, screenshots are compared pixel-by-pixel across browsers and viewports automatically, and flagged diffs go to a dashboard for review.

When to use it

  • Catching CSS regressions after a redesign by comparing page screenshots
  • Running screenshot comparisons across Chrome, Firefox, and Safari viewports
  • Adding visual baseline checks to an existing Playwright or Cypress test suite
  • Comparing Storybook component renders between PR branches
  • Checking responsive layouts at multiple breakpoints against stored baselines
