在运行咕噜测试在约曼（1.0RC1）脚手架角（1.0.7）的应用程序，我得到了以下错误：

While running grunt test on a Yeoman (1.0RC1) scaffolded Angular (1.0.7) app, I'm getting the following error:

TypeError: 'undefined' is not a function (evaluating '$scope.$parent.userLoggedIn(true)')

userLoggedIn（）是父控制器内 index.js 。该函数本身运行的角度应用程序内的罚款。

userLoggedIn() is within a parent controller index.js. The function itself runs fine within the angular app.

不会出现在控制器我的其他 $范围。$父布尔或字符串变量这个错误，因此它直接关系到父之内调用函数。

This error doesn't occur on my other $scope.$parent boolean or strings variables in the controller, so it's related directly to calling functions within a parent.

我在想，我是不是使用 $范围。$父错误的方式或者说我需要定义我的 index.js 控制器的测试，但测试噶文档零星的，所以很难知道的。

I'm thinking that I'm either using $scope.$parent the wrong way or that I need to define my index.js controller in the test, but Karma testing documentation is sporadic, so it's hard to know.

编辑：这里是控制器：

'use strict';

angular.module('uiApp')
  .controller('LookupCtrl', ['$scope', function ($scope) {
    $scope.awesomeThings = [
      'HTML5 Boilerplate',
      'AngularJS',
      'Karma'
    ];

    $scope.$parent.userLoggedIn(true);

  }]);

下面是测试：

'use strict';

describe('Controller: LookupCtrl', function () {

  // load the controller's module
  beforeEach(module('uiApp'));

  var LookupCtrl,
    scope;

  // Initialize the controller and a mock scope
  beforeEach(inject(function ($controller, $rootScope) {
    scope = $rootScope.$new();
    LookupCtrl = $controller('LookupCtrl', {
      $scope: scope
    });
  }));

  it('should attach a list of awesomeThings to the scope', function () {
    expect(scope.awesomeThings.length).toBe(3);
  });

});

（是的，我知道，我只是使用默认的 awesomeThings 测试吧。我是新来的角测试）。

(Yes I know I'm just using the default awesomeThings test for now. I'm new to Angular testing).

推荐答案

您正在给一个控制器中的 rootScope ，它不具有 $父（这是根）。改变你的控制器code正确地调用它（使用原型链），你会被刚好路过罚款。{我：道具} 为对象

You're giving the controller a rootScope, which doesn't have $parent (it's the root). Change your controller code to call it correctly (using the prototype chain) and you'll be fine by just passing {my: props} as an object.
