Angularjs $scope在使用Karma进行测试时未定义

我是一个测试AngularJS的完全初学者，所以任何建议都非常感谢

当我尝试运行Karma Start时，我遇到了一个错误，看起来像这样

Chrome 54.0.2840 (Mac OS X 10.11.6) DashboardCtrl Should Exist FAILED
Error: [$injector:unpr] Unknown provider: $scopeProvider <- $scope <- DashboardCtrl

angular.module('myApp.controllers', [])
.controller('DashboardCtrl', function($rootScope, $scope, API, $ionicModal, $window, $ionicLoading) {

包含以下部分内容和所有必需的结束标记；）

我的测试代码如下所示

describe('DashboardCtrl', function(){
var $controller, DashboardCtrl;

beforeEach(angular.mock.module('ui.router'));
beforeEach(angular.mock.module('myApp.controllers'));

beforeEach(inject(function(_$controller_){
    $controller = _$controller_;
    DashboardCtrl = $controller('DashboardCtrl', {});
}));

it('Should Exist', function(){
    expect(DashboardCtrl).toBeDefined();
})
});

我已经看到了一些关于这个的其他帖子，但我就是不知道我错在哪里了，谢谢大家的帮助

您忘记了创建和注入

$scope

describe('DashboardCtrl', function(){
    var $scope,
        DashboardCtrl;

    beforeEach(angular.mock.module('ui.router'));
    beforeEach(angular.mock.module('myApp.controllers'));

    beforeEach(inject(function($rootScope, $controller){
        $scope = $rootScope.$new();

        DashboardCtrl = $controller('DashboardCtrl', {
            $scope: $scope
        });
    }));

    it('Should Exist', function(){
        expect(DashboardCtrl).toBeDefined();
    })
});

您必须将依赖项注入controllerThanks，这样就消除了错误，但是，它已经停止了我的$rootScope函数在控制器中的工作，只是想知道我是否也需要注入rootScope？如果是这样的话，是否会有不同的做法？如果（！$rootScope.isSessionActive（））{$window.location.href=（''）；}以上是失败的代码，这是在services.js$rootScope.isSessionActive=函数（）中定义的（{返回$window.localStorage.token&&$window.localStorage.username？true:false；}@BRollinson你试过我的解决方案吗？
