*
* *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');

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

/**
 * @ngdoc function
 * @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
