AngularJs單元測試茉莉花+卡姆拉+角模擬了getModules功能

Question

創建單元測試這是我的dashboardService，我想創建單元測試的getModules

============== ================================================== ================

(function (angular) { 
    'use strict'; 

    var __Name = "dashboardService";  
    var __Path = "components/dashboard";  

    angular 
    .module(window.__env.appName,[]) 
     .factory(__Name, serviceFunc); 

    serviceFunc.$inject = ['$cookies','$http']; 

    function serviceFunc($cookies,$http) {  
     return { 
         getmodules: function (cb) { 
          $http({ 
           method: 'GET', 
           url:'/home/modulesInfo' 

          }).then(function successCallback(response) { 
           cb(true, response); 
          }, function errorCallback(response) { 
           cb(false, response) 
          }); 
         } 

      } 
    } 

})(window.angular); 

=========================== =========================================

以下是我的說明文件（dashboardService.spec.js）

'use strict'; 
describe('getmodules', function() { 
    beforeEach(function() { module('ngMockE2E'); }); 
    var service, httpBackend, defaultAlertFactory; 
    beforeEach(function() { 
     debugger; 
     module('myApp'); 
     module(function ($provide) { 
      var dashboardService = { 
       getMegetmodules: function() { 
        // mocked method 
        return ['david', 'James', 'Sam']; 
       } 
      }; 

      $provide.service('defaultAlertFactoryA', dashboardService); 
     }); 
     angular.mock.inject(function ($injector) { 
      service = $injector.get('defaultAlertFactoryA'); 
      httpBackend = $injector.get('$httpBackend'); 

     }); 

    }); 

    //describe('getmodules', function() { 
    it("should return a list of getmodules", inject(function() { 
     debugger; 
     httpBackend.expectGET('/Home/modulesInfo').respond(['david', 'James', 'Sam']); 
     service.getmodules(function (result) { 
      expect(result).toEqual(["david", "James", "Sam"]); 
     }); 
     httpBackend.flush(); 
    })) 
    //}) 

}）;

謝謝！

看來你有一個錯字，你dashboardService是定義一個名爲getMegetmodules功能，並在測試功能，你打電話給service.getmodules，你應該這樣做：

module(function ($provide) { 
    var dashboardService = { 
     getModules: function() { 
      // mocked method 
      return ['david', 'James', 'Sam']; 
     } 
    }; 

    $provide.service('defaultAlertFactoryA', dashboardService); 
}); 

而在你的測試功能：

it("should return a list of getmodules", inject(function() { 
    debugger; 
    httpBackend.expectGET('/Home/modulesInfo').respond(['david', 'James', 'Sam']); 
    service.getModules(function (result) { 
     expect(result).toEqual(["david", "James", "Sam"]); 
    }); 
    httpBackend.flush(); 
})); 

希望有所幫助！ pd：我認爲你不需要那個httpBackend.flush（）
