npm install mocha chai --save-dev

  same as
npm i -D mocha chai

create a test file src/index.test.js

 var expect = require('chai').expect;
 var starWars = require('./index');
 describe('starwars-names', function() {
   describe('all', function() {
     it('should be an array of strings', function() {
       expect(starWars.all).to.satisfy(isArrayOfStrings);
       function isArrayOfStrings(array) {
         return array.every(function(item) {
           return typeof item === 'string';
         });
       }
     });
     it('should contain `Luke Skywalker`', function() {
       expect(starWars.all).to.include('Luke Skywalker');
     });
   });
   describe('random', function() {
     it('should return a random item from the starWars.all', function() {
       var randomItem = starWars.random();
       expect(starWars.all).to.include(randomItem);
     });
   });
 });

change package.json to run tests (automatically on update -w)

 "scripts": {
   "test": "mocha src/index.test.js -w"
 },

 npm test
