What is the correct way to frame this test spec?

So I get this to work in my editor but I keep getting the error saying it passes with a broken clone.js function that should fail. What am I doing wrong?

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

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


    it('should clone object', function () {
        let users = {id:93}
      let newU = clone(users);

      expect(clone(users)).to.eql({ id: 93 });
    });
});
clone.js 
function clone (objectForCloning) {
    return Object.assign({}, objectForCloning)
}

module.exports = clone

Hey Antony,

Did you try with

expect(newU).to.eql(users);

Thanks Jesus, However it does not work. I don't know why, but i had to use expect(clone(users)).to.deep.equal(users); . I was under the impression it was just a more verbose way of doing the same thing, but I guess not. Funny thing is I tried that first but was using "to.deep.equals" and moved on to other methods.

I was going to suggest you that but when I read the documentation it seemed the same to me
