 *
 * *NOTE*: this is not an injectable instance, just a globally available mock class of `Date`.
 *
 * Mock of the Date type which has its timezone specified via constructor arg.
 *
 * The main purpose is to create Date-like instances with timezone fixed to the specified timezone
 * offset, so that we can test code that depends on local timezone settings without dependency on
 * the time zone settings of the machine where the code is running.
 *
 * @param {number} offset Offset of the *desired* timezone in hours (fractions will be honored)
 * @param {(number|string)} timestamp Timestamp representing the desired time in *UTC*
 *
 * @example
 * !!!! WARNING !!!!!
 * This is not a complete Date object so only methods that were implemented can be called safely.
 * To make matters worse, TzDate instances inherit stuff from Date via a prototype.
 *
 * We do our best to intercept calls to "unimplemented" methods, but since the list of methods is
 * incomplete we might be missing some non-standard methods. This can result in errors like:
 * "Date.prototype.foo called on incompatible Object".
 *
 * ```js

 * @description
 * Fake HTTP backend implementation suitable for unit testing applications that use the
 * {@link ng.$http $http service}.
 *
 * <div class="alert alert-info">
 * **Note**: For fake HTTP backend implementation suitable for end-to-end testing or backend-less
 * development please see {@link ngMockE2E.$httpBackend e2e $httpBackend mock}.
 * </div>
 *
 * During unit testing, we want our unit tests to run quickly and have no external dependencies so
 * we don’t want to send [XHR](https://developer.mozilla.org/en/xmlhttprequest) or
 * [JSONP](http://en.wikipedia.org/wiki/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 $httpBackend) and use it to verify
 * the requests and respond with some testing data without sending a request to a real server.
 *
 * There are two ways to specify what test data should be returned as http responses by the mock
 * backend when the code under test makes http requests:
 *
 * - `$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 asynchronously. If we preserved
 * this behavior in unit testing, we'd have to create async unit tests, which are hard to write,
 * to follow and to maintain. But neither can the testing mock respond synchronously; 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. This preserves
 * 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 when unit testing a controller.
 * First we create the controller under test:
 *
  ```js
  // The module code
  angular
    .module('MyApp', [])
    .controller('MyController', MyController);

  // The controller code
  function MyController($scope, $http) {
    var authToken;

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

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

      $http.post('/add-msg.py', message, { headers: headers } ).then(function(response) {
        $scope.status = '';
      }).catch(function() {
        $scope.status = 'Failed...';
      });
    };
  }
  ```
 *
 * Now we setup the mock backend and create the test specs:
 *
  ```js
    // testing controller
    describe('MyController', function() {
       var $httpBackend, $rootScope, createController, authRequestHandler;

       // Set up the module
       beforeEach(module('MyApp'));

       beforeEach(inject(function($injector) {
         // Set up the mock http service responses
         $httpBackend = $injector.get('$httpBackend');
         // backend definition common for all tests
         authRequestHandler = $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 fail authentication', function() {

         // Notice how you can change the response even after it was set
         authRequestHandler.respond(401, '');

         $httpBackend.expectGET('/auth.py');
         var controller = createController();
         $httpBackend.flush();
         expect($rootScope.status).toBe('Failed...');
       });


       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 sent, 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();
       });
    });
  ```
 *
 * ## Dynamic responses
 *
 * You define a response to a request by chaining a call to `respond()` onto a definition or expectation.
 * If you provide a **callback** as the first parameter to `respond(callback)` then you can dynamically generate
 * a response based on the properties of the request.
 *
 * The `callback` function should be of the form `function(method, url, data, headers, params)`.
 *
 * ### Query parameters
 *
 * By default, query parameters on request URLs are parsed into the `params` object. So a request URL
 * of `/list?q=searchstr&orderby=-name` would set `params` to be `{q: 'searchstr', orderby: '-name'}`.
 *
 * ### Regex parameter matching
 *
 * If an expectation or definition uses a **regex** to match the URL, you can provide an array of **keys** via a
 * `params` argument. The index of each **key** in the array will match the index of a **group** in the
 * **regex**.
 *
 * The `params` object in the **callback** will now have properties with these keys, which hold the value of the
 * corresponding **group** in the **regex**.
 *
 * This also applies to the `when` and `expect` shortcut methods.
 *
 *
 * ```js
 *   $httpBackend.expect('GET', /\/user\/(.+)/, undefined, undefined, ['id'])
 *     .respond(function(method, url, data, headers, params) {
 *       // for requested url of '/user/1234' params is {id: '1234'}
 *     });
 *
 *   $httpBackend.whenPATCH(/\/user\/(.+)\/article\/(.+)/, undefined, undefined, ['user', 'article'])
 *     .respond(function(method, url, data, headers, params) {
 *       // for url of '/user/1234/article/567' params is {user: '1234', article: '567'}
 *     });
 * ```
 *
 * ## Matching route requests
 *
 * For extra convenience, `whenRoute` and `expectRoute` shortcuts are available. These methods offer colon
 * delimited matching of the url path, ignoring the query string. This allows declarations
 * similar to how application routes are configured with `$routeProvider`. Because these methods convert
 * the definition url to regex, declaration order is important. Combined with query parameter parsing,
 * the following is possible:
 *
  ```js
    $httpBackend.whenRoute('GET', '/users/:id')
      .respond(function(method, url, data, headers, params) {
        return [200, MockUserList[Number(params.id)]];
      });

    $httpBackend.whenRoute('GET', '/users')
      .respond(function(method, url, data, headers, params) {
        var userList = angular.copy(MockUserList),
          defaultSort = 'lastName',
          count, pages, isPrevious, isNext;

        // paged api response '/v1/users?page=2'
        params.page = Number(params.page) || 1;

        // query for last names '/v1/users?q=Archer'
        if (params.q) {
          userList = $filter('filter')({lastName: params.q});
        }

        pages = Math.ceil(userList.length / pagingLength);
        isPrevious = params.page > 1;
        isNext = params.page < pages;

        return [200, {
          count:    userList.length,
          previous: isPrevious,
          next:     isNext,
          // sort field -> '/v1/users?sortBy=firstName'
          results:  $filter('orderBy')(userList, params.sortBy || defaultSort)
                      .splice((params.page - 1) * pagingLength, pagingLength)
        }];
      });

 * @name $httpBackend
 * @module ngMockE2E
 * @description
 * Fake HTTP backend implementation suitable for end-to-end testing or backend-less development of
 * applications that use the {@link ng.$http $http service}.
 *
 * <div class="alert alert-info">
 * **Note**: For fake http backend implementation suitable for unit testing please see
 * {@link ngMock.$httpBackend unit-testing $httpBackend mock}.
 * </div>
 *
 * 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 $httpBackend flushes mocked out requests
 * automatically, closely simulating the behavior of the XMLHttpRequest object.
 *
 * To setup the application to run with this http backend, you have to create a module that depends
 * on the `ngMockE2E` and your application modules and defines the fake backend:
 *
 * ```js
 *   var myAppDev = angular.module('myAppDev', ['myApp', 'ngMockE2E']);
 *   myAppDev.run(function($httpBackend) {
 *     var 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) {
 *       var phone = angular.fromJson(data);
 *       phones.push(phone);
 *       return [200, phone, {}];
 *     });
 *     $httpBackend.whenGET(/^\/templates\//).passThrough(); // Requests for templates are handled by the real server
 *     //...
 *   });
 * ```
 *
 * Afterwards, bootstrap your app with this new module.
 *
 * ## Example
 * <example name="httpbackend-e2e-testing" module="myAppE2E" deps="angular-mocks.js">
 * <file name="app.js">
 *   var myApp = angular.module('myApp', []);

   * Use sharedInjector when you want to take advantage of Jasmine's `beforeAll()`, or mocha's

  /**
   * @ngdoc function

   * @description
   *
   * *NOTE*: This function is also published on window for easy access.<br>
   * *NOTE*: This function is declared ONLY WHEN running tests with jasmine or mocha
   *
   * The inject function wraps a function into an injectable function. The inject() creates new
   * instance of {@link auto.$injector $injector} per test, which is then used for
   * resolving references.
   *
   *
   * ## Resolving References (Underscore Wrapping)
   * Often, we would like to inject a reference once, in a `beforeEach()` block and reuse this
   * in multiple `it()` clauses. To be able to do this we must assign the reference to a variable
   * that is declared in the scope of the `describe()` block. Since we would, most likely, want
   * the variable to have the same name of the reference we have a problem, since the parameter
   * to the `inject()` function would hide the outer variable.
   *
   * To help with this, the injected parameters can, optionally, be enclosed with underscores.
   * These are ignored by the injector when the reference name is resolved.
   *
   * For example, the parameter `_myService_` would be resolved as the reference `myService`.
   * Since it is available in the function body as _myService_, we can then assign it to a variable
   * defined in an outer scope.
   *
   * ```
   * // Defined out reference variable outside
   * var myService;
   *
   * // Wrap the parameter in underscores
   * beforeEach( inject( function(_myService_){
   *   myService = _myService_;
   * }));
   *
   * // Use myService in a series of tests.
   * it('makes use of myService', function() {
   *   myService.doStuff();
   * });
   *
   * ```
   *
   * See also {@link angular.mock.module angular.mock.module}
   *
   * ## Example
   * Example of what a typical jasmine tests looks like with the inject method.
   * ```js
   *
   *   angular.module('myApplicationModule', [])
   *       .value('mode', 'app')
   *       .value('version', 'v1.0.1');
   *
   *
   *   describe('MyApp', function() {
   *
   *     // You need to load modules that you want to test,
   *     // it loads only the "ng" module by default.
   *     beforeEach(module('myApplicationModule'));
   *
   *
   *     // inject() is used to inject arguments of all given functions
   *     it('should provide a version', inject(function(mode, version) {
   *       expect(version).toEqual('v1.0.1');
   *       expect(mode).toEqual('app');
   *     }));
   *
   *
   *     // The inject and module method can also be used inside of the it or beforeEach
   *     it('should override a version and test the new version is injected', function() {
   *       // module() takes functions or strings (module aliases)
   *       module(function($provide) {
   *         $provide.value('version', 'overridden'); // override version here
   *       });
   *
   *       inject(function(version) {
   *         expect(version).toEqual('overridden');
   *       });
   *     });
   *   });
   *
   * ```
   *
   * @param {...Function} fns any number of functions which will be injected using the injector.
