jest-preview is a debugging tool for Jest that opens a browser preview of rendered test output. It helps developers inspect the DOM produced during component and UI tests, making visual verification easier while tests run locally. The project is commonly used with Jest and Testing Library workflows in React, Vue, and other frontend applications that render HTML interfaces.
