AngularJS and $httpBackend

I was helping out someone with their first attempt at an AngularJS website and they sent me the html and javascript file. The problem was that they used a web service to which I don’t have access so I needed a way to simulate that web service. I thought about writing my own version of the MVC web service but that seemed like overkill for what should just be a quick project. What I did find was $httpBackend which you can use to mock $http call with, the documentation for $httpBackend is here

The code is also on JSFiddle

//You need to inject the ngMockE2E module into your application's module
var myModule = angular.module('myModule', [ 'ngMockE2E']);
 
//Adding a global variable that can be injected into controllers and services
myModule.value('globalBaseUri', '/myService');
 
myModule.run(['$httpBackend', 'globalBaseUri', function($httpBackend,globalBaseUri) {
 
	//I wrapped the data to mimic how the Service is returning the data
