Unit testing for a Vite project uses Vitest to provide a Jest-compatible API with native ESM and TypeScript support. You can validate client and server codebases immediately by installing Vitest and running tests with built-in watch mode.
Mocking modules in native ESM unit tests is handled natively by Vitest. It provides built-in mocking support alongside fixtures and snapshots, enabling robust test-driven development without requiring additional external mocking libraries.
Yes, you can use a Jest-compatible API for testing Vite-powered applications because Vitest is specifically designed to provide this compatibility. It integrates directly with Vite to offer fast, incremental tests while maintaining familiar Jest syntax.
Vitest fully supports multi-project configurations and concurrent tests within Vite-based setups. It provides config-driven test environments that satisfy type safety and tooling integration across both client and server codebases.
You generate code coverage for TypeScript and JSX in Vite using Vitest's built-in coverage tools. It automatically handles TypeScript and JSX transpilation across client and server code, providing coverage reports without needing separate instrumentation plugins.
