Provides Vue.js testing best practices, patterns, and solutions for common pitfalls using Vitest, Vue Test Utils, and Playwright.

Write behavior-focused React component tests with React Testing Library, Vitest/Jest, MSW for network mocking, and accessibility assertions using axe, while deciding when to use component tests versus Playwright/Cypress end-to-end tests.

Cypress E2E testing framework. Covers commands, assertions, and component testing. Use for end-to-end testing. USE WHEN: user mentions "cypress", "e2e test", "cy.get", "cy.visit", asks about "cypress intercept", "component testing", "cypress commands" DO NOT USE FOR: Unit tests - use `vitest` or `jest`; Multi-tab scenarios - Cypress doesn't support; Native mobile apps - use Appium; Performance testing - use dedicated tools

Write Jest or Vitest unit tests with React Testing Library and Playwright E2E tests for Next.js projects. Use when testing components with RTL, mocking APIs with MSW, or creating Playwright user flow tests.

Generates Angular code and provides architectural guidance for projects, components, services, and more, covering reactivity, forms, dependency injection, routing, accessibility, animations, styling, testing, and CLI tooling.

Jest testing framework. Covers unit tests, mocking, and snapshots. Use for testing React and Node.js projects. USE WHEN: user mentions "jest", "jest test", "snapshot test", asks about "jest.fn", "jest.mock", "toMatchSnapshot", "React testing" DO NOT USE FOR: E2E tests - use `playwright` or `cypress`; Vite projects - use `vitest` instead; React component testing alone - combine with `testing-library`

Generates unit tests, integration tests, and E2E tests for React/Next.js applications by scanning components, analyzing coverage reports, and scaffolding Playwright test files.

Write and review unit tests for Vue 3 + TypeScript + Vitest + Pinia codebases, covering components, composables, and stores with behavior-first assertions.

Converts Stitch designs into modular Vite and React components, or syncs existing components to match updated designs.

Converts Stitch designs into modular Vite and React components, using MCP networking and AST-based validation to ensure code quality.

Vitest testing framework. Covers unit tests, mocking, and coverage. Use for testing Vite-based and Node.js projects. USE WHEN: user mentions "vitest", "vite test", "unit test", asks about "vi.fn", "vi.mock", "test coverage", "mock functions", "test vite project" DO NOT USE FOR: E2E tests - use `playwright` instead; React component testing - combine with `testing-library`; Jest projects - use `jest` instead
