测试模块AngularJS与/ Jasmine＆Karma

Question

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）组织模块。

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'));，我应该可以访问我的布局模块中的控制器，服务，过滤器和指令。

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：

思考？

Answer 1

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

Answer 2

这种错误主要是由于karma.config.js文件中的文件声明不正确而引起的。对于karma-jasmine的设置，karma.config.js文件的file:[]块内的所有文件都应按顺序加载。主模块具有依赖注入任何自定义服务，然后首先加载该服务，然后加载主模块。
