无法单元测试角度控制器与服务模拟

问题描述：

我开始与AngularJs和我正在面临一个问题，当试图单元测试一个服务作为依赖项的控制器。该应用程序按预期工作，但不是单元测试。我与茉莉花测试以下错误：无法单元测试角度控制器与服务模拟

Error: [$injector:modulerr] Failed to instantiate module ghhweb.register due to: Error: [$injector:unpr] Unknown provider: $stateProvider

我的模块代码：

var registerModule = angular.module('ghhweb.register',[]); 

registerModule.config(function($stateProvider, $locationProvider){ 
    var registerState = { 
     name: 'register', 
     url: '/register', 
     controller: 'RegisterController', 
     templateUrl: 'modules/register/views/register.html' 
    }; 

    $stateProvider.state(registerState); 
});

我的控制器代码：

var registerController = angular.module('ghhweb.register.controller',[]); 

registerController.controller('RegisterController', ['$scope', 
    'userRestService', function($scope, userRestService){ 
    $scope.callCheckExistingMail = function(){ 
     $scope.userEmail = userRestService.checkExistingMail($scope.userEmail); 
    }; 
}]);

我的规格代码：

describe('controller register module unit tests', function(){ 
    describe('check user service implementation', function(){ 

     beforeEach(module('ghhweb.register')); 

     it('should call checkExistinMail in userRestService', inject(function(
       $rootScope, $controller){ 
      // make a userRestService 
      var userRestService = { 
       checkExistingMail: function() {} 
      }; 

      spyOn(userRestService, "checkExistingMail"); 

      controller('RegisterController', {$scope: scope, 
       userRestService: userRestService }); 

      expect(userRestService.checkExistingMail).toHaveBeenCalled(); 
     })); 

    }); 

});

我已经试过很多的教程和检查的几个职位像这样：

angular-unit-test-controllers-mocking-service-inside-controller
injecting-a-mock-into-an-angularjs-service

我想我有一个配置问题的地方，但我无法解决它。

有没有人有想法？

答

我怀疑我以前的测试代码不适用于我现有的库版本。我使用的是：

"devDependencies": { 
"bower": "^1.8.0", 
"http-server": "^0.9.0", 
"jasmine-core": "^2.4.1", 
"karma": "^1.3.0", 
"karma-chrome-launcher": "^2.0.0", 
"karma-firefox-launcher": "^1.0.0", 
"karma-jasmine": "^1.0.2", 
"phantomjs": "^2.1.7", 
"protractor": "^4.0.9"

经过进一步调查我改写了测试代码如下：

describe('controller register module unit tests implementation', function(){ 

    var $controller; 
    var $scope; 
    var userRestService; 

    beforeEach(module('ghhweb.register.controller', function($provide){ 
     userRestService = jasmine.createSpyObj('userRestService' 
      , ['checkExistingMail']); 

     userRestService.checkExistingMail.and.returnValue(0); 

     $provide.value('userRestService', userRestService); 
    })); 


    beforeEach(inject(function(_$controller_, $rootScope,_userRestService_){ 
     $scope = $rootScope.$new(); 
     userRestService = _userRestService_; 
     $controller = _$controller_('RegisterController', { 
      $scope: $scope, 
      userRestService: userRestService 
     }); 
     $scope.callCheckExistingMail(); 
    })); 

    it('should call userRestService', function(){ 
     expect(userRestService.checkExistingMail).toHaveBeenCalled(); 
    }); 
});

测试现在运行正常！
