Yes, Vitest supports TypeScript natively. You can configure your testing environment using a vitest.config.ts or vite.config.ts file to define settings like coverage thresholds and test execution rules.

You can mock functions and modules in Vite tests using the built-in vi.fn and vi.mock methods. These Jest-compatible mocking utilities allow you to isolate components and control dependencies during unit testing.

Yes, Vitest supports component testing for Vue, React, and Svelte applications. It leverages Vite-native test execution to provide fast feedback while running your UI component test suites.

Migrating to Vitest is the best way to achieve a Vite-native testing setup because it offers a Jest-compatible API surface with familiar describe and it blocks, allowing you to transition your test suites without rewriting assertions.

You can configure coverage thresholds for your test suite by defining the settings in your vitest.config.ts or vite.config.ts file. Vitest allows you to customize these limits to enforce code coverage standards in your CI pipeline.
