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

Currently, I am implementing unit tests for my project and there is a file that contains window.location.href.

I want to mock this to test and here is my sample code:

it("method A should work correctly", () => {
      const url = "http://dummy.com";
      Object.defineProperty(window.location, "href", {
        value: url,
        writable: true
      });
      const data = {
        id: "123",
        name: null
      };
      window.location.href = url;
      wrapper.vm.methodA(data);
      expect(window.location.href).toEqual(url);
    });

But I get this error:

TypeError: Cannot redefine property: href
        at Function.defineProperty (<anonymous>)

How should I resolve it?

You can try:

window = Object.create(window);
const url = "http://dummy.com";
Object.defineProperty(window, 'location', {
  value: {
    href: url
  },
  writable: true // possibility to override
});
expect(window.location.href).toEqual(url);  

Have a look at the Jest Issue for that problem:
