使用茉莉花和业力测试打字稿角度时出现Angularjs错误

Question

我想用 Karma 和 Jasmine 测试我的基于 AngularJS 和 TypeScript 的应用程序。

我编辑的controllerSpecs.ts：

/// <reference path="../references.ts" />

describe('ConfigCtrl', () => {
var configCtrl, scope;

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

beforeEach(angular.mock.inject(($rootScope) => {
    scope = $rootScope.$new();
    configCtrl = new App.TestCtrl(scope);
}));

it('should be true', () => {
    expect(true).toBe(true);
});
});

我的app.ts：

module App {
import TypewritingCtrl = App.TypewritingCtrl;
import MenuCtrl = App.MenuCtrl;
var typescrip: ng.IModule;
var typewritingapp: ng.IModule = angular.module("typewritingApp", ["ngRoute", "ui.bootstrap", "LocalStorageModule", "ui.event", "timer"])
    .controller("TestCtrl", ["$scope", TestCtrl])

}

我的TestController.ts：

/// <reference path="../references.ts" />
module App {
export class TestCtrl {
    constructor($scope: ng.IRootScopeService) {

    }
}
}

当我尝试运行测试时，业力写给我的错误：

如果我从我的代码中删除注入部分，它会成功运行并且测试通过。谁能帮助我做错了什么？

我们应该请求服务 $rootScope 作为本地 $scope 生成器：

// beforeEach(angular.mock.inject(($scope) => {
beforeEach(angular.mock.inject(($rootScope) =>
{
    // HERE we do create a $scope from $rootScope
    scope = $rootScope.$new();
    configCtrl = new App.TestCtrl(scope);
}));
