/** * Mocks the window.matchMedia API for testing environments. * * This function creates a mock implementation of the window.matchMedia method that * is commonly used for responsive design and media queries. The mock always returns * a MediaQueryList-like object with standard methods and properties, but with default * values (matches set to false). * * This allows tests of components that use media queries to run without errors in * Jest's JSDOM environment, which doesn't implement matchMedia natively. * * Ideal for testing: * - Responsive components * - Components that adapt to screen size changes * - Components that use CSS media query matching in JavaScript * * @example * // In your jest setup file * import { setupMatchMediaMock } from '@trackunit/react-test-setup'; * * setupMatchMediaMock(); */ export declare const setupMatchMediaMock: () => void;
