Testing an MEVN Application Chapter 9

Let's rerun mocha. This should again fail, because we haven't added a method to our

module. So, let's go ahead and do that. In add.js, let's add the following code:

var addUtility = {}

addUtility.sum = function () {

'use strict';

return true;

}

module.exports = addUtility;

Let's rerun mocha. The spec should pass now:

Now, let's add the functional part to the sum method. In add_spec.js, add the following

code:

var assert = require("assert")

var addUtility = require("./../add.js");

describe('Add', function(){

describe('addUtility', function(){

it('should have a sum method', function(){

assert.equal(typeof addUtility, 'object');

assert.equal(typeof addUtility.sum, 'function');

})

it('addUtility.sum(5, 4) should return 9', function(){

assert.deepEqual(addUtility.sum(5, 4), 9)
