FAQPage Schema

How do I set up fast unit testing for TypeScript without complex configuration?▼

Vitest provides zero-config TypeScript testing with native ESM support and Jest-compatible API. It eliminates setup overhead while delivering instant watch mode and built-in coverage reporting through simple vitest.config.ts configuration.

Can I use Vitest to test tRPC procedures and Zod schemas?▼

Yes. Vitest is optimized for testing tRPC procedures, Zod schemas, utilities, and React components in Vite-based projects. It runs in Node or jsdom environments with full TypeScript integration and zero additional configuration needed.

What's the difference between Vitest and Jest for TypeScript projects?▼

Vitest uses ESM by default and integrates directly with Vite for instant test execution without transformation overhead. Jest requires additional TypeScript configuration and has slower startup; Vitest prioritizes speed and modern JavaScript standards.

How do I configure test coverage and environment setup with Vitest?▼

Vitest handles coverage and environment configuration through setupFiles, include patterns, and environment selection in vitest.config.ts. The @vitest/coverage-v8 dependency enables detailed coverage reports without extra tooling.

Does Vitest support mocking for unit tests?▼

Yes. The vitest-mock-extended dependency provides TypeScript-first mocking utilities for unit tests. Combined with Vitest's built-in mocking capabilities, it enables type-safe mock creation for complex dependencies.
