Challenge where you check a functions object against its properties for a match not passing.

I'm having trouble even in the documentation for which method would work to check an object that was cloned against its copy.

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

describe('clone', function () {
    var clone = require('./clone.js')
    it('checks clone object against all properties', function () {

        expect(clone(Object.assign).to.have.all.keys('object');

    })
})
clone.js 
function clone (objectForCloning) {
    return Object.assign({}, objectForCloning)
}

module.exports = clone

Hi Nadine,

There are several ways you could pass this challenge. Here are a couple to consider:

var object =  { prop1: 1, prop2: 2 };
expect(clone(object)).to.deep.equal(object);

This will test that the clone is exactly the same as the original object, including values.

var object = { prop1: 1, prop2: 2 };
expect(clone(object)).to.have.all.keys('prop1', 'prop2');

This one will test that the dummy object will have all of the keys passed in. Both of these examples should work.

Happy coding.
Leslie
