cannot get test to pass..read all suggested answers on community and still won't work....error message says expected test to fail but it passed....but still won't let me pass the challenge...??

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

describe('clone', function () {
    var clone = require('./clone.js')
    it('some description string', function () {

        // YOUR CODE HERE
      var obj1 = {foo: 1, bar: 2};

      expect(clone(obj1)).to.deep.equal(obj1);

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

module.exports = clone

Seems like this code challenge is expecting the use of Chai's include method.

var expect = require('chai').expect

describe('clone', function () {
    var clone = require('./clone.js')
    it('some description string', function () {
        var obj = { a: 1, b: 0 }
        expect(clone(obj)).to.include(obj)
    })
})

Certainly a bit confusing, because there are a number of ways you can assert varying degrees of sameness between two object literals with Chai.
