我得到这个常见错误错误：[$injector：unpr]未知提供者：$scopeProvider< - $scope with my test case.我知道这是一个常见的,并且很少有其他线程解释解决方案.但我真的无法找到我的问题的答案.谁能指出我正确的方向？ ViewMeetingCtrl,

(function () {
    'use strict';
    angular.module('MyApp').controller('ViewMeetingCtrl',ViewMeetingCtrl);

    ViewMeetingCtrl.$inject = ['$scope','$state','$http','$translate','notificationService','meetingService','$modal','meeting','attachmentService'];

    function ViewMeetingCtrl($scope,$state,$http,$translate,notificationService,meetingService,$modal,meeting,attachmentService) {
        $scope.meeting = meeting;
        $scope.test = "testvalue";
        if (meeting.Status == 'Cancelled')
        {
            $scope.actionButtons = false;
        }
        else
        {
            $scope.actionButtons = true;
        }

        //more code
    }
})();

MeetingCtrlSpec.js

describe('ViewMeetingCtrl',function () {
    var $rootScope,scope,$controller,meetingService;

    beforeEach(angular.mock.module('MyApp'));

    beforeEach(inject(function ($rootScope,meetingService) {
        scope = $rootScope.$new();
        $controller('ViewMeetingCtrl',{
            meetingService: meetingService,'$rootScope' : $rootScope,scope: scope
        });       

    }));

    it('should change greeting value if name value is changed',function () {
        //some assertion
    });
});

错误跟踪：

更换

$controller('ViewMeetingCtrl',{
        meetingService: meetingService,scope: scope
    });

通过

$controller('ViewMeetingCtrl',$scope: scope
    });

必须使用名为$scope的参数注入控制器,而不是作用域.并且$rootScope不是控制器注入的协作者的一部分.
