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

Solution 1:

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:

2020 Update

Basic

The URL object has a lot of the same functionality as the Location object. In other words, it includes properties such as pathname, search, hostname, etc. So for most cases, you can do the following:

delete window.location
window.location = new URL('https://www.example.com')

Advanced

You can also mock Location methods that you might need, which don't exist on the URL interface:

const location = new URL('https://www.example.com')
location.assign = jest.fn()
location.replace = jest.fn()
location.reload = jest.fn()

delete window.location
window.location = location

Solution 3:

I have resolved this issue by adding writable: true and move it to beforeEach

Here is my sample code:

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

Solution 4:

Solution for 2019 from GitHub:

delete global.window.location;
global.window = Object.create(window);
global.window.location = {
  port: '123',
  protocol: 'http:',
  hostname: 'localhost',
};

Solution 5:

The best is probably to create a new URL instance, so that it parses your string like location.href does, and so it updates all the properties of location like .hash, .search, .protocol etc.

it("method A should work correctly", () => {
  const url = "http://dummy.com/";
  Object.defineProperty(window, "location", {
    value: new URL(url)
  } );

  window.location.href = url;
  expect(window.location.href).toEqual(url);

  window.location.href += "#bar"
  expect(window.location.hash).toEqual("#bar");
});
