End-to-end testing patterns with Playwright for full-stack Python/React applications. Use when writing E2E tests for complete user workflows (login, CRUD, navigation), critical path regression tests, or cross-browser validation. Covers test structure, page object model, selector strategy (data-testid > role > label), wait strategies, auth state reuse, test data management, and CI integration. Does NOT cover unit tests or component tests (use pytest-patterns or react-testing-patterns).
Generates consistent UI components, layouts, and design tokens following a design system. Enforces spacing, color, typography, and accessibility standards across React/TypeScript projects. Use when creating new UI components, building page layouts, choosing colors or typography, setting up design tokens, or reviewing UI code for design consistency. Covers 8pt spacing grid, Tailwind CSS token usage, shadcn/ui primitives, WCAG 2.1 AA compliance, responsive breakpoints, semantic HTML structure, and TypeScript component interfaces. Does NOT cover backend implementation (use python-backend-expert), testing (use react-testing-patterns), or deployment (use deployment-pipeline).
Test React components with Testing Library patterns. Covers queries (getBy/findBy/queryBy), user-event interactions, async testing (findBy vs waitFor), accessibility testing, and MSW integration for API mocking. Use when: testing React components, simulating user interactions, testing forms, mocking API calls with MSW, or writing accessible tests. Keywords: testing-library, react testing library, getByRole, user-event, waitFor, MSW, screen.
Expert in testing strategies for React, Next.js, and NestJS applications covering unit tests, integration tests, E2E tests, and testing best practices
Set up Vitest testing environment for Next.js projects
Comprehensive QA and testing skill for quality assurance, test automation, and testing strategies for ReactJS, NextJS, NodeJS applications. Includes test suite generation, coverage analysis, E2E testing setup, and quality metrics. Use when designing test strategies, writing test cases, implementing test automation, performing manual testing, or analyzing test coverage.
Use when feature flag tests fail, flags need updating, understanding @gate pragmas, debugging channel-specific test failures, or adding new flags to React.
This skill should be used when the user asks to "generate tests", "write unit tests", "analyze test coverage", "scaffold E2E tests", "set up Playwright", "configure Jest", "implement testing patterns", or "improve test quality". Use for React/Next.js testing with Jest, React Testing Library, and Playwright.
Jest with TypeScript - Industry standard testing framework with 70% market share, mature ecosystem, React Testing Library integration
