Detect unintended visual changes in UI by comparing screenshots across versions. Use for visual regression, screenshot diff, Percy, Chromatic, UI testing, and visual validation.
Implements visual regression testing with screenshot comparison, diff detection, and CI integration using Playwright or Chromatic. Use when users request "visual testing", "screenshot testing", "UI regression", "visual diff", or "Chromatic setup".
Canvas/DOM parity testing for the foreignObject serializer. Use when comparing the SVG foreignObject render path against the native Blink canvas path, writing pixel-diff tests, or hunting canvas vs DOM rendering inconsistencies.
Rigorous visual validation expert specializing in UI testing, design system compliance, and accessibility verification. Masters screenshot analysis, visual regression testing, and component validation. Use PROACTIVELY to verify UI modifications have achieved their intended goals through comprehensive visual analysis.
Playwright E2E testing expert for browser automation, cross-browser testing, visual regression, network interception, and CI integration. Use for E2E test setup, flaky tests, or browser automation challenges.
Sets up Storybook for component documentation with controls, actions, accessibility testing, and visual regression. Use when users request "Storybook setup", "component documentation", "UI library", "component stories", or "design system docs".
Storybook UI component development and testing. Use for component testing.
Plan and build comprehensive Playwright E2E test suites with Page Object Model, authentication state persistence, custom fixtures, visual regression, and CI integration. Uses interview-driven planning to clarify critical user flows, auth strategy, test data approach, and parallelization before writing any tests.
Figma-to-code design handoff patterns including Figma Variables to design tokens pipeline, component spec extraction, Dev Mode inspection, Auto Layout to CSS Flexbox/Grid mapping, and visual regression with Applitools. Use when converting Figma designs to code, documenting component specs, setting up design-dev workflows, or comparing production UI against Figma designs.
Expert in designing robust test frameworks using Playwright, Cypress, and AI-driven testing tools.
Design and implement visual regression testing for UI changes. Defines screenshot coverage, rendering stabilization, baseline management, and CI integration (e.g., Playwright screenshots, Percy/Chromatic). Use when UI/styling/layout changes need protection against regressions, or when adding screenshot-based tests to a web/WASM/desktop UI.
Expert in end-to-end testing with Playwright, the modern cross-browser testing framework. Specializes in test generation, page object patterns, visual regression testing, and CI/CD integration. Handles complex testing scenarios including authentication flows, API mocking, and mobile emulation.
