Vue.js - How to mock window.location.href with Jest + Vuejs?

To mock window.location.href in Jest tests for Vue.js components, you can use jest.spyOn to create a spy on Object.defineProperty and then set window.location.href to a mock value. Here's how you can do it:

// YourComponent.spec.js import { mount } from '@vue/test-utils'; import YourComponent from '@/components/YourComponent.vue'; describe('YourComponent', () => { it('should redirect to a new URL when button is clicked', () => { const mockHref = 'http://example.com'; const spy = jest.spyOn(window, 'Object.defineProperty').mockImplementation(() => {}); const wrapper = mount(YourComponent); wrapper.find('button').trigger('click'); expect(spy).toHaveBeenCalledWith(window, 'location.href', { value: mockHref }); spy.mockRestore(); }); });

This code sets up a spy on Object.defineProperty, which is used internally by Vue.js to set properties on the window object. It then mocks window.location.href to a mock URL value when a button in the component is clicked. Finally, it asserts that Object.defineProperty was called with the correct arguments.

Make sure to replace '@/components/YourComponent.vue' with the correct path to your component.

This approach allows you to mock window.location.href in Jest tests for Vue.js components. However, keep in mind that window.location.href is read-only, so you may need to adjust your code accordingly if you have logic that directly assigns to window.location.href.
