/**
* @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.
*
*
*
* Request expectations Backend definitions
* Syntax
* .expect(...).respond(...)
* .when(...).respond(...)
*
*
* Typical usage
* strict unit tests
* loose (black-box) unit testing
*
*
* Fulfills multiple requests
* NO
* YES
*
*
* Order of requests matters
* YES
* NO
*
*
* Request required
* YES
* NO
*
*
* Response required
* optional (see below)
* YES
*
*
*
* 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').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!';
});
};
}
```
*
* 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 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 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 $http service}.
*
* *Note*: For fake http backend implementation suitable for unit testing please see
* {@link ngMock.$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.
* *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.
