使用茉莉花和业力测试工厂方法。得到错误：[$ injector：unpr]

Question

如何使用Jasmine和karma测试此工厂方法getItemList？

I am getting error: [$injector:unpr] http://errors.angularjs

这是我的代码。

(function() { 

    angular.module('riskCanvasApp').factory('itemsService', itemsService); 

    itemsService.$inject = [ '$http', '$q','$compile', 'UrlService', 
     'accountDetailsMainService', 'sharedService', 'authenticationSvc' ]; 

    function itemsService($http, $q, $compile, urlService, accountDetailsMainService, 
          sharedService, authenticationSvc) { 


     function getItemList() { 
      // Code here 

     } 

我的单元测试代码是

'use strict'; 
(function() { 

describe('itemsService Spec', function() { 

    var _authenticationSvc; 
    var _$http; 
    var _$q; 
    var _$compile; 
    var _urlService; 
    var myFactory; 

    beforeEach(module('riskCanvasApp')); 

    beforeEach(inject(function($http, $q, $compile, urlService, authenticationSvc) { 
     debugger 
     _$http = $http; 
     _$q = $q; 
     _$compile = $compile; 
     _urlService = urlService; 
     _authenticationSvc = authenticationSvc; 

     var $injector = angular.injector(['riskCanvasApp']); 
     myFactory = $injector.get('itemsService'); 

     var deferred = $q.defer(); 
    })); 

    it('should call AuthService', function() { 
     debugger 
     var data = myFactory.getItemList(); 
     // 
    }); 

}); 
}());

我得到了一个解决方案

'use strict'; 
    (function() { 
    //1. Describe the test 
    describe('myserv', function() { 
     var itemsService; 
     var authenticationSvc; 
     var urlService; 
     var $q; 
     var $scope; 
     var httpBackend; 

     //2. Load the module and inject dependencies 
     beforeEach(function() { 
      module('riskCanvasApp'); 
      inject(function($injector){ 
       itemsService = $injector.get('itemsService'); 
       authenticationSvc = $injector.get('authenticationSvc'); 
       urlService = $injector.get('UrlService'); 
       $q = $injector.get('$q'); 
       $scope = $injector.get('$rootScope').$new(); 
       httpBackend = $injector.get('$httpBackend'); 
      }); 
     }); 

     //3. make sure no expectations were missed in your tests. 
     afterEach(function() { 
      httpBackend.verifyNoOutstandingExpectation(); 
      httpBackend.verifyNoOutstandingRequest(); 
     }); 

     //4. write the test cases 
     it('ServiceTestSpec', function() { 
      // expect to make sure this is defined and valid function. 
      expect(itemsService.itemList).toBeDefined(); 
      expect(itemsService.itemList).toEqual(jasmine.any(Function)); // Service to get Account type, Account sub type, Risk lavels, Assignment status, Sub types, Due dates 

      // expect to make sure this is defined and valid function. 
      expect(itemsService.createFilter).toBeDefined(); 
      expect(itemsService.createFilter).toEqual(jasmine.any(Function)); // Create filter 

      // expect to make sure this is defined and valid function. 
      expect(itemsService.updateFilter).toBeDefined(); 
      expect(itemsService.updateFilter).toEqual(jasmine.any(Function)); // Edit filter 

      // expect to make sure this is defined and valid function. 
      expect(itemsService.setDefaultFilter).toBeDefined(); 
      expect(itemsService.setDefaultFilter).toEqual(jasmine.any(Function)); // Set default filter 

      // expect to make sure this is defined and valid function. 
      expect(itemsService.deleteFilter).toBeDefined(); 
      expect(itemsService.deleteFilter).toEqual(jasmine.any(Function)); // Delete filter 

      // expect to make sure this is defined and valid function. 
      expect(itemsService.getFilters).toBeDefined(); 
      expect(itemsService.getFilters).toEqual(jasmine.any(Function)); // List filter 

      // Handle error that requests logged in user 
      httpBackend.whenGET('app/login/LoginView.html').respond({}); 
      httpBackend.flush(); 

      // variable in this scope for you to test. 
      var returnData = {}; 

      // expectGET to make sure this is called once. 
      httpBackend.expectGET("sampleJson/itemsObject.json").respond(returnData); 

      // make the call. 
      var returnedPromise = itemsService.itemList(); 

      // set up a handler for the response, that will put the result into a variable in this scope for you to test. 
      var result; 
      returnedPromise.then(function (response) { 
       result = response.data; 
      }); 

      // flush the backend to "execute" the request to do the expectedGET assertion. 
      httpBackend.flush(); 

      // check the result. 
      expect(result).toEqual(returnData); 
     }); 

    }); 
}());
