SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

This Skill guides frontend teams to implement robust testing practices across unit, component, and visual/E2E levels, reducing regressions and maintenance costs.

Core Features & Use Cases

  • Unit Tests: Create fast, isolated tests for hooks and utilities using Vitest.
  • Component Tests: Validate rendering and user interactions with React Testing Library.
  • Visual/E2E Tests: Automate browser-based checks with Playwright MCP, Storybook, and real user flows.

Quick Start

  1. Initialize test tooling in your project (Vitest, Testing Library, and Playwright MCP).
  2. Add tests for a hook, a component, and a page, then run the appropriate test commands.
  3. Review results and iterate to improve coverage.

FAQPage Schema
How do I automate frontend testing for React applications using Vitest and Playwright?▼

Automate frontend testing for React by defining patterns for unit, component, and visual E2E tests. You use Vitest for isolated hook tests, React Testing Library for component interactions, and Playwright MCP for browser-based user flows.

What is the best way to structure unit and component tests for React hooks?▼

Structure unit and component tests by creating fast, isolated tests for hooks and utilities using Vitest, then validating rendering and user interactions with React Testing Library to ensure deterministic results across development projects.

Do I need Playwright MCP configured to run visual and E2E tests?▼

Yes, you need Playwright MCP configured in your project to execute visual and E2E tests. The tooling requires Vitest, Testing Library, and Playwright MCP to be set up to generate reliable browser-based check results.

Can I use Vitest and React Testing Library for testing component rendering and interactions?▼

Yes, you can use Vitest alongside React Testing Library to validate component rendering and user interactions. This combination provides deterministic results for component testing across your React development projects.

How do I set up frontend test automation tooling in my project?▼

Set up frontend test automation by initializing Vitest, Testing Library, and Playwright MCP in your project. Add tests for a hook, a component, and a page, then run the appropriate test commands and iterate to improve coverage.

What are the limitations of using Playwright MCP for visual testing?▼

Playwright MCP for visual testing requires proper configuration in your project to execute tests and generate reliable results. Without initializing the tooling alongside Vitest and Testing Library, browser-based checks cannot run deterministically.
