测试模块化AngularJS w / Jasmine&因果报应 [英] Testing modular AngularJS w/ Jasmine & Karma

问题描述

努力在Jasmine / Karma中设置单元测试。我有一个服务依赖的控制器，该服务有另一个服务依赖。我不是按类型（指令，服务等）组织我的模块，而是按功能（布局，摘要视图等）组织。

Struggling to get unit testing set up in Jasmine/Karma. I have a controller with a service dependency, and that service has another service dependency. I am not organizing my modules by type (Directives, Services, etc), but rather by feature (layout, summaryView, etc).

这是架构：

angular.module('myApp', ['ngResource', 'myApp.base', 'myApp.layout','myApp.common']);
angular.module('myApp.base', ['myApp.common']);
angular.module('myApp.common',[]);
angular.module('myApp.layout',['myApp.common']);

控制器：

angular.module('myApp.layout')
    .controller('LayoutCtrl', ['$scope', '$rootScope', '$timeout', 'layoutService', 'urlService', 'BaseService',
        function ($scope, $rootScope, $timeout, layoutService, urlService, BaseService) {
            //controller code here
    });

布局服务：

 angular.module('myApp.layout')
    .service('layoutService', ['$http', '$resource', '$rootScope', '$location', '$route', 'errorHandlingService', 'utilService',
        function ($http, $resource, $rootScope, $location, $route, errorHandlingService, utilService) {
            //service code here
    });

根据我的理解，如果我只是包含 beforeEach（module（'myApp） .layout'））; ，我应该可以访问布局模块中的控制器，服务，过滤器和指令。

From what I understand, if I simply include beforeEach(module('myApp.layout'));, I should have access to my controllers, services, filters, and directives in my layout module.

相反，以下代码失败：

describe('Layout Controller', function() {
  var ctrl, scope, service;

  beforeEach(module('myApp'));
  beforeEach(module('myApp.layout'));
  beforeEach(inject(function($controller, $rootScope, layoutService) {

      scope = $rootScope.$new();
      service = layoutService;
      //Create the controller with the new scope
      ctrl = $controller('LayoutCtrl', {$scope: scope, layoutService: service});
      dump(scope);
    }));
    it('should exist', function() {
        expect(ctrl).toBeDefined();
    });
});

出现此错误：

想法？

推荐答案

通常，未知提供程序错误来自未加载或以错误顺序加载的文件。在测试运行时检查哪些文件存在。

Often a Unknown Provider error comes from files not being loaded, or being loaded in the incorrect order. Check which files are present while your tests are running.
