SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

Streamline Vitest adoption for Next.js and React projects by auto-detecting existing test setups and providing a guided, ready-to-run configuration and sample tests.

Core Features & Use Cases

  • Detects an existing test runner (Vitest or Jest) and adapts configuration and test templates accordingly.
  • Generates a minimal Vitest config (vitest.config.ts) and a setup file with Testing Library presets.
  • Provides ready-to-run example tests for components and utilities to accelerate onboarding and ensure test coverage.

Quick Start

Run this skill in your project root to scaffold Vitest setup and example tests.

Frequently Asked Questions about testing-vitest

High-intent search queries and answers about installing and using this skill.

FAQPage Schema
How do I set up Vitest in a Next.js or React project?

You can scaffold Vitest setup by running an automation tool in your project root that detects existing test runners and generates a compatible vitest.config.ts, setup files with Testing Library presets, and ready-to-run example tests.

Can I add Vitest to a project that already uses Jest?

Yes, you can add Vitest to a project already using Jest because the setup process detects existing test runners and adapts the generated Vitest configuration and test templates to ensure compatibility with your current setup.

What dependencies do I need to run Vitest tests with React Testing Library?

To run Vitest tests with React Testing Library, you need the vitest package and related testing libraries such as @testing-library/react installed in your project to execute the generated configuration and example tests.

Does Vitest auto-configure jsdom for Next.js component testing?

Yes, Vitest auto-configures jsdom for Next.js component testing by generating a minimal vitest.config.ts and a dedicated setup file that includes Testing Library presets required for rendering components in a simulated DOM environment.

What is the best way to scaffold unit tests for React components?

The best way to scaffold unit tests for React components is using an automation tool that generates ready-to-run example tests and a pre-configured setup file, accelerating onboarding and ensuring immediate test coverage.

Why does my Vitest setup fail to detect my existing test configuration?

Your Vitest setup might fail if the automation tool cannot properly detect your existing test runner configuration, requiring you to ensure your current test setup files are present in the expected project root location.
