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





.everyoneloves__top-leaderboard:empty,.everyoneloves__mid-leaderboard:empty,.everyoneloves__bot-mid-leaderboard:empty{ height:90px;width:728px;box-sizing:border-box;
}

Currently, I am implementing unit test for my project and there is a file that contained 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>)


I had tried some solutions but not resolve it. I need some hints to help me get out of this trouble. Plz help.

          You can try:



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


          Have a look at the Jest Issue for that problem:
