E2E-Test fehlgeschlagen

Question

Ich versuche, eine Beispielanwendung in Angular 2 einzurichten, gerade versuche ich, den e2e-Testteil zu testen. Ich habe wenig Wissen über das Jasmine-Framework oder die Winkelmesser-Bibliothek, die Angular 2 verwendet.

Also ich bin nicht sicher, warum ich immer diese Fehlermeldung, wenn ich ng e2e laufen (I Angular CLI bin mit)

Der Fehler erhalte ich:

[09:41:10] I/direct - Using ChromeDriver directly... 
[09:41:10] I/launcher - Running 1 instances of WebDriver 
[09:41:12] E/launcher - Error: TSError: ? Unable to compile TypeScript 
e2e\app.e2e-spec.ts (16,4): Cannot find name 'browser'. (2304) 
e2e\app.e2e-spec.ts (17,19): Cannot find name 'element'. (2304)

e2e\app.e2e-spec.ts (18,5): Supplied parameters do not match any signature of ca 
ll target. (2346) 

Mein Testfall (app.e2e- spec.ts)

import { WebPage } from './app.po'; 

describe('web App', function() { 
    let page: WebPage; 

    beforeEach(() => { 
    page = new WebPage(); 
    }); 

    it('should display message saying app works',() => { 
    page.navigateTo(); 
    expect(page.getParagraphText()).toEqual('Hello World'); 
    }); 

    it('Has a greeting', function() { 
    browser.get('/index.html'); 
    var greeting = element(by.id('h2Id')); 
    expect().getText(greeting).toEqual('Hello, World!'); 
    }); 


});

};

app.e2e-spec.ts:

expect(). GetText (Begrüßung) .toEqual ('Hallo, Welt!');

=> expect(greeting.getText()).toEqual('Hello, World!');
