If you’ve encountered the “Error: Not implemented: window.scrollTo” in Jest, it indicates that Jest, a JavaScript testing framework, does not by default implement browser-specific methods like window.scrollTo. Here’s a quick fix:
// setup-jest.js
// Mock implementation of window.scrollTo
const windowMock = {
scrollTo: jest.fn(),
};
// Assign the mock to the global object
Object.assign(global, windowMock);
This code snippet creates a mock function for window.scrollTo and assigns it to the global object, effectively bypassing the error in Jest environments. Remember, Jest is designed for unit testing JavaScript code and lacks some browser-specific functionalities.
