AngularJS茉莉花测试：TypeError：'undefined'不是一个对象

新角和以下从我以前的帖子angularjs jasmine tests: Variable vm not found 我在我的角度测试有一个TypeError，并不知道什么问题是。下面是我的测试：AngularJS茉莉花测试：TypeError：'undefined'不是一个对象

(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); 
      }); 
     }); 
    }); 

    }); 

})();

我得到的错误如下：

你能显示控制器的代码？这将有助于更好地理解问题。看起来'DeliveriesController'不仅取决于'$ scope'，还取决于'DeliveriesService'。当你实例化控制器时，你应该提供它所有的依赖关系（无论是真实的还是模拟的）。 – Stubb0rn

你说得对。情况就是如此。我添加了DeliveriesService作为注入到测试中，它工作。谢谢你 – noobcoder

@ Stubb0rn请发表您的评论作为答案。它真的帮了我，但如果你把它作为评论，它不会很容易找到。 –

该解决方案适用于我，是解决方案。谢谢@StubbOrn

看起来你正在控制器中使用DeliveriesService。

无论何时使用服务，您都需要确保注入该服务或使用$ provider添加服务。

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) 
}));
