It seems like the one of the contributer declared that he is not planning expose jsdom to global under the jest environment.

However, you could use Object.defineProperty(window, 'location', {value: '…'} API to approach it, like the developer in Facebook do. In your case it could be like:

    Object.defineProperty(window, 'location', {
      value: {
        search: ...
      },
    })

Good luck!
