努力在 Jasmine/Karma 中设置单元测试。我有一个具有服务依赖关系的控制器，并且该服务具有另一个服务依赖关系。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）组织我的模块。

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
    });

排版服务：

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

据我了解，如果我只是简单地包含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：

未知提供程序错误通常来自未加载的文件，或以不正确的顺序加载。在测试运行时检查哪些文件存在。

此类错误主要是由于karma.config.js文件中的文件声明不正确造成的。对于karma-jasmine的设置， karma.config.jsfile:[]文件块中的所有文件应该按预期加载的顺序排列。主模块正在对任何自定义服务进行依赖注入，然后先加载该服务，然后再加载主模块。
