* {@link http://en.wikipedia.org/wiki/JSONP JSONP} requests to a real server. All we really need is
* to verify whether a certain request has been sent or not, or alternatively just let the
* application make requests, respond with pre-trained responses and assert that the end result is
* what we expect it to be.
*
* This mock implementation can be used to respond with static or dynamic responses via the
* `expect` and `when` apis and their shortcuts (`expectGET`, `whenPOST`, etc).
*
* When an Angular application needs some data from a server, it calls the $http service, which
* sends the request to a real server using $httpBackend service. With dependency injection, it is
* easy to inject $httpBackend mock (which has the same API as $httpBackend) and use it to verify
* the requests and respond with some testing data without sending a request to real server.
*
* There are two ways to specify what test data should be returned as http responses by the mock
* backend when the code under test makes http requests:
*
* - `$httpBackend.expect` - specifies a request expectation
* - `$httpBackend.when` - specifies a backend definition
*
*
* # Request Expectations vs Backend Definitions
*
* Request expectations provide a way to make assertions about requests made by the application and
* to define responses for those requests. The test will fail if the expected requests are not made
* or they are made in the wrong order.
*
* Backend definitions allow you to define a fake backend for your application which doesn't assert
* if a particular request was made or not, it just returns a trained response if a request is made.
* The test will pass whether or not the request gets made during testing.
*
*
* <table class="table">
*   <tr><th width="220px"></th><th>Request expectations</th><th>Backend definitions</th></tr>
*   <tr>
*     <th>Syntax</th>
*     <td>.expect(...).respond(...)</td>
*     <td>.when(...).respond(...)</td>
*   </tr>
*   <tr>
*     <th>Typical usage</th>
*     <td>strict unit tests</td>
*     <td>loose (black-box) unit testing</td>
*   </tr>
*   <tr>
*     <th>Fulfills multiple requests</th>
*     <td>NO</td>
*     <td>YES</td>
*   </tr>
*   <tr>
*     <th>Order of requests matters</th>
*     <td>YES</td>
*     <td>NO</td>
*   </tr>
*   <tr>
*     <th>Request required</th>
*     <td>YES</td>
*     <td>NO</td>
*   </tr>
*   <tr>
*     <th>Response required</th>
*     <td>optional (see below)</td>
*     <td>YES</td>
*   </tr>
* </table>
*
* In cases where both backend definitions and request expectations are specified during unit
* testing, the request expectations are evaluated first.
*
* If a request expectation has no response specified, the algorithm will search your backend
* definitions for an appropriate response.
*
* If a request didn't match any expectation or if the expectation doesn't have the response
* defined, the backend definitions are evaluated in sequential order to see if any of them match
* the request. The response from the first matched definition is returned.
*
*
* # Flushing HTTP requests
*
* The $httpBackend used in production, always responds to requests with responses asynchronously.
* If we preserved this behavior in unit testing, we'd have to create async unit tests, which are
* hard to write, follow and maintain. At the same time the testing mock, can't respond
* synchronously because that would change the execution of the code under test. For this reason the
* mock $httpBackend has a `flush()` method, which allows the test to explicitly flush pending
* requests and thus preserving the async api of the backend, while allowing the test to execute
* synchronously.
*
*
* # Unit testing with mock $httpBackend
* The following code shows how to setup and use the mock backend in unit testing a controller.
* First we create the controller under test
*
 <pre>
 // The controller code
 function MyController($scope, $http) {
   var authToken;

   $http.get('/auth.py').success(function(data, status, headers) {
     authToken = headers('A-Token');
     $scope.user = data;
   });

   $scope.saveMessage = function(message) {
     var headers = { 'Authorization': authToken };
     $scope.status = 'Saving...';

     $http.post('/add-msg.py', message, { headers: headers } ).success(function(response) {
       $scope.status = '';
     }).error(function() {
       $scope.status = 'ERROR!';
     });
   };
 }
 </pre>
*
* Now we setup the mock backend and create the test specs.
*
 <pre>
   // testing controller
   describe('MyController', function() {
      var $httpBackend, $rootScope, createController;

      beforeEach(inject(function($injector) {
        // Set up the mock http service responses
        $httpBackend = $injector.get('$httpBackend');
        // backend definition common for all tests
        $httpBackend.when('GET', '/auth.py').respond({userId: 'userX'}, {'A-Token': 'xxx'});

        // Get hold of a scope (i.e. the root scope)
        $rootScope = $injector.get('$rootScope');
        // The $controller service is used to create instances of controllers
        var $controller = $injector.get('$controller');

        createController = function() {
          return $controller('MyController', {'$scope' : $rootScope });
        };
      }));

      afterEach(function() {
        $httpBackend.verifyNoOutstandingExpectation();
        $httpBackend.verifyNoOutstandingRequest();
      });

      it('should fetch authentication token', function() {
        $httpBackend.expectGET('/auth.py');
        var controller = createController();
        $httpBackend.flush();
      });

      it('should send msg to server', function() {
        var controller = createController();
        $httpBackend.flush();

        // now you don’t care about the authentication, but
        // the controller will still send the request and
        // $httpBackend will respond without you having to
        // specify the expectation and response for this request

        $httpBackend.expectPOST('/add-msg.py', 'message content').respond(201, '');
        $rootScope.saveMessage('message content');
        expect($rootScope.status).toBe('Saving...');
        $httpBackend.flush();
        expect($rootScope.status).toBe('');
      });

      it('should send auth header', function() {
        var controller = createController();
        $httpBackend.flush();

        $httpBackend.expectPOST('/add-msg.py', undefined, function(headers) {
          // check if the header was send, if it wasn't the expectation won't
          // match the request and the test will fail
          return headers['Authorization'] == 'xxx';
        }).respond(201, '');

        $rootScope.saveMessage('whatever');
        $httpBackend.flush();

* @ngdoc object
* @name ngMockE2E.$httpBackend
* @description
* Fake HTTP backend implementation suitable for end-to-end testing or backend-less development of
* applications that use the {@link ng.$http $http service}.
*
* *Note*: For fake http backend implementation suitable for unit testing please see
* {@link ngMock.$httpBackend unit-testing $httpBackend mock}.
*
* This implementation can be used to respond with static or dynamic responses via the `when` api
* and its shortcuts (`whenGET`, `whenPOST`, etc) and optionally pass through requests to the
* real $httpBackend for specific requests (e.g. to interact with certain remote apis or to fetch
* templates from a webserver).
*
* As opposed to unit-testing, in an end-to-end testing scenario or in scenario when an application
* is being developed with the real backend api replaced with a mock, it is often desirable for
* certain category of requests to bypass the mock and issue a real http request (e.g. to fetch
* templates or static files from the webserver). To configure the backend with this behavior
* use the `passThrough` request handler of `when` instead of `respond`.
*
* Additionally, we don't want to manually have to flush mocked out requests like we do during unit
* testing. For this reason the e2e $httpBackend automatically flushes mocked out requests
* automatically, closely simulating the behavior of the XMLHttpRequest object.
*
* To setup the application to run with this http backend, you have to create a module that depends
* on the `ngMockE2E` and your application modules and defines the fake backend:
*
* <pre>
*   myAppDev = angular.module('myAppDev', ['myApp', 'ngMockE2E']);
*   myAppDev.run(function($httpBackend) {
*     phones = [{name: 'phone1'}, {name: 'phone2'}];
*
*     // returns the current list of phones
*     $httpBackend.whenGET('/phones').respond(phones);
*
*     // adds a new phone to the phones array
*     $httpBackend.whenPOST('/phones').respond(function(method, url, data) {
*       phones.push(angular.fromJson(data));
*     });
*     $httpBackend.whenGET(/^\/templates\//).passThrough();
*     //...
*   });
* </pre>
*
* Afterwards, bootstrap your app with this new module.
