how can I compare two objects that have not been created?

I think I need to use the deep equality but how to compare when is not created yet

clone_spec.js
var expect = require('chai').expect

describe('clone', function () {
    var clone = require('./clone.js')
    it('should comparethe clone with the cloned object', function () {

        // YOUR CODE HERE
        expect(clone(objectForCloning)).to.deep.equal(objectForCloning);
    })
});
clone.js
function clone (objectForCloning) {
    return Object.assign({}, objectForCloning)
}

module.exports = clone

just create an object. You can declare some arbitrary object in the describe function and then pass it to the clone function and just check that the output of the clone is identical to the object you created.

describe('clone', function () {
    var clone = require('./clone.js')

    var obj = {something: true};

    it('should comparethe clone with the cloned object', function () {

        // YOUR CODE HERE
        expect(clone(obj)).to.have.keys("something");
    })
});
