如何用摩卡测试Angular 2？

这几天来我一直在拼命想这个问题，但我哪儿也去不了。。我正试图用Mocha测试我的Angular 2应用程序（如果有必要的话，基于SystemJS），但我不知道如何获取控制器实例

我正在尝试我能想到的最简单的案例

import {bootstrap} from 'angular2/platform/browser';
import {App} from '../app/app';
import {Type} from 'angular2/core';

describe('Login', () => {
    let app:App;

    beforeEach((done) => {
        console.log(bootstrap);
        bootstrap(<Type>App)
            .then(result => result.instance)
            .then(instance => {
                app = instance;
                done();
            });
    });

    it('Test for App to Exist', (done) => {
        console.log(app);
        done();
    });
});

---

如我所料，记录一个未定义的

。有没有人能让这样的东西发挥作用？这里的目标是对控制器进行单元测试，所以我非常努力地避免使用phantomJS/webdriver/等等。

我认为mocha不能直接使用，因为它只在节点上运行（在服务器端渲染HTML字符串时，可能使用Angular2 universal）。也就是说，你可以在背景中使用摩卡咖啡和browserify。我正在为该设置编写一个

然后，测试可以如下所示：

// import everything needed for to run Angular (we're running in PhantomJS by defualt but other browsers are possible too)
import "es6-shim";
import "es6-promise";
import "zone.js";
import "rxjs";
import "reflect-metadata";

import "../../typings/browser.d.ts";

import {Injector, enableProdMode} from "angular2/core";
import {HTTP_PROVIDERS} from "angular2/http";


// import stuff we need to instantiate component
import GithubComponent from "./gihub-component";
import GithubService from "./github-service";
import Config from "../config";

import * as sinon from "sinon";

enableProdMode();

describe("github-component", () => {

    let injector: Injector;
    let component: any;
    let service: any;

    beforeEach(() => {
        // instantiate Angular 2 DI context
        injector = Injector.resolveAndCreate([
            HTTP_PROVIDERS,
            GithubComponent,
            GithubService,
            Config
        ]);
        component = injector.get(GithubComponent);
        service = injector.get(GithubService);
        sinon.spy(service, "getRepos");
    });

    afterEach(() => {
        service.getRepos.restore();
    });

    it("searches for repository", () => {
        component.query.updateValue("test");

        return setTimeout(() => {
            sinon.assert.calledOnce(service.getRepos);
            sinon.assert.calledWith(service.getRepos, "test");
        }, 300);
    });

});
