   *
   * *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".

   * var newYearInBratislava = new TzDate(-1, '2009-12-31T23:00:00Z');

   * 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 AngularJS 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.
   *
   *

   *   <tr><th width="220px"></th><th>Request expectations</th><th>Backend definitions</th></tr>

   *     <th>Syntax</th>
   *     <td>.expect(...).respond(...)</td>
   *     <td>.when(...).respond(...)</td>
   *   </tr>
   *   <tr>
   *     <th>Typical usage</th>
   *     <td>strict unit tests</td>

   *     <td>NO</td>

   *     <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;
      }).catch(function() {
        $scope.status = 'Failed...';
      });
  
      $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'}
   *     });
   *
   *   $httpBackend.whenPATCH(/\/user\/(.+)\/article\/(.+)/, undefined, undefined, ['user', 'article'])
   *     .respond(function(method, url, data, headers, params) {
   *       // for url of '/user/1234/article/567' params is {user: '1234', article: '567'}
   *     });
   * ```
   *
   * ## Matching route requests
   *
   * For extra convenience, `whenRoute` and `expectRoute` shortcuts are available. These methods offer colon
   * delimited matching of the url path, ignoring the query string and trailing slashes. This allows declarations
   * similar to how application routes are configured with `$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)
          }];
        });
    ```

   *  First, download the file:

   *    `"//ajax.googleapis.com/ajax/libs/angularjs/X.Y.Z/angular-mocks.js"`

   *  * [Yarn](https://yarnpkg.com) e.g. `yarn add angular-mocks@X.Y.Z`
   *  * [Bower](http://bower.io) e.g. `bower install angular-mocks#X.Y.Z`
   *  * [code.angularjs.org](https://code.angularjs.org/) (discouraged for production use)  e.g.
   *    `"//code.angularjs.org/X.Y.Z/angular-mocks.js"`
   *
   * where X.Y.Z is the AngularJS version you are running.
   *
   * Then, configure your test runner to load `angular-mocks.js` after `angular.js`.

   * @ngdoc service
   * @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', []);

   * This method can be used to change which mocked responses `$httpBackend` returns, when defining

   * By default, `$httpBackend` returns the first definition that matches. When setting

   * one that was added last.
   *
   * ```js
   * hb.when('GET', '/url1').respond(200, 'content', {});
   * hb.when('GET', '/url1').respond(201, 'another', {});
   * hb('GET', '/url1'); // receives "content"

   * ```

     * @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}
     *
