AngularJS茉莉花測試：TypeError：'undefined'不是一個對象

新角和以下從我以前的帖子angularjs jasmine tests: Variable vm not found 我在我的角度測試有一個TypeError，並不知道什麼問題是。下面是我的測試：AngularJS茉莉花測試：TypeError：'undefined'不是一個對象

(function(){ 
'use strict'; 
describe('Testing DeliveriesController', function() { 

    beforeEach(module('app.deliveries')); 

    describe('Testing deliveries controller', function(){ 
     var vm, controller; 

     beforeEach(inject(function($controller, $rootScope){ 
      vm = $rootScope.$new(); 
      controller = $controller('DeliveriesController', {$scope:vm}); 
     })); 

     afterEach(function() { 
      vm = undefined; 
      controller = undefined; 
     }); 

     describe('priorities length', function(){ 
      it('it should test priority length', function() { 
       expect(vm.priorities.length).toBe(0); 
      }); 
     }); 
    }); 

    }); 

})();

我得到的錯誤如下：

你能顯示控制器的代碼？這將有助於更好地理解問題。看起來'DeliveriesController'不僅取決於'$ scope'，還取決於'DeliveriesService'。當你實例化控制器時，你應該提供它所有的依賴關係（無論是真實的還是模擬的）。 – Stubb0rn

你說得對。情況就是如此。我添加了DeliveriesService作爲注入到測試中，它工作。謝謝你 – noobcoder

@ Stubb0rn請發表您的評論作爲答案。它真的幫了我，但如果你把它作爲評論，它不會很容易找到。 –

禮貌：從@StubbbOrn評論：

該解決方案適用於我，是解決方案。謝謝@StubbOrn

看起來你正在控制器中使用DeliveriesService。

無論何時使用服務，您都需要確保注入該服務或使用$ provider添加服務。

beforeEach(inject(function($controller, $rootScope, _DeliveriesService_){ 
      vm = $rootScope.$new(); 
      DeliveriesSrvc = _DeliveriesService_; 
      controller = $controller('DeliveriesController', {$scope:vm}); 
     }));

或

beforeEach(module(function ($provide) { 
    mockObj = { 
     functionName: jasmine.createSpy('functionName') 
    } 
    $provide.value('DeliveriesService',mockObj) 
}));
