       * *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
       * var newYearInBratislava = new TzDate(-1, '2009-12-31T23:00:00Z');
       * newYearInBratislava.getTimezoneOffset() => -60;
       * newYearInBratislava.getFullYear() => 2010;

       * @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 donâ€™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.
       *
       *

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

       *     <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 donâ€™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)
              }];
            });

           * Flushes pending requests using the trained responses. Requests are flushed in the order they
           * were made, but it is also possible to skip one or more requests (for example to have them
           * flushed later). This is useful for simulating scenarios where responses arrive from the server
           * in any order.
           *
           * If there are no pending requests to flush when the method is called, an exception is thrown (as
           * this is typically a sign of programming error).
           *
           * @param {number=} count - Number of responses to flush. If undefined/null, all pending requests
           *     (starting after `skip`) will be flushed.
           * @param {number=} [skip=0] - Number of pending requests to skip. For example, a value of `5`
           *     would skip the first 5 pending requests and start flushing from the 6th onwards.

       * The `ngMock` module provides support to inject and mock AngularJS services into unit tests.
       * In addition, ngMock also extends various core AngularJS services such that they can be
       * inspected and controlled in a synchronous manner within test code.
       *
       * @installation
       *
       *  First, download the file:
       *  * [Google CDN](https://developers.google.com/speed/libraries/devguide#angularjs) e.g.
       *    `"//ajax.googleapis.com/ajax/libs/angularjs/X.Y.Z/angular-mocks.js"`
       *  * [NPM](https://www.npmjs.com/) e.g. `npm install angular-mocks@X.Y.Z`
       *  * [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`.
       * This example uses <a href="http://karma-runner.github.io/">Karma</a>:
       *
       * ```

       *  are ready to go!

       * @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">

       *
       *     ctrl.phones = [];
       *     ctrl.newPhone = {
       *       name: ''
       *     };
       *
       *     ctrl.getPhones = function() {

           *
           * *NOTE*: This function is declared ONLY WHEN running tests with jasmine or mocha

           * This function ensures a single injector will be used for all tests in a given describe context.
           * This contrasts with the default behaviour where a new injector is created per test case.
           *
           * Use sharedInjector when you want to take advantage of Jasmine's `beforeAll()`, or mocha's
           * `before()` methods. Call `module.sharedInjector()` before you setup any other hooks that
           * will create (i.e call `module()`) or use (i.e call `inject()`) the injector.
           *
           * You cannot call `sharedInjector()` from within a context already using `sharedInjector()`.
           *
           * ## Example
           *
           * Typically beforeAll is used to make many assertions about a single operation. This can
           * cut down test run-time as the test setup doesn't need to be re-run, and enabling focussed
           * tests each with a single assertion.
           *
           * ```js
           * describe("Deep Thought", function() {
           *
           *   module.sharedInjector();

           *     // that was provided to the beforeAll() hook. Therefore we can test the generated answer

           * @name angular.mock.inject
           * @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.
