ページオブジェクトモデルフレームワークでBrowserstackを使用

Question

こんにちは私は、自動化されたテストをブラウザスタックに統合しようとしています。残念ながら、POMフレームワークを使用するのに役立つオンラインのものはありません。

私はseen thisですが、これは便利ですが基本テンプレートであり、ドライバを渡すためにページオブジェクトモデルを使用していません。 「オブジェクト参照がオブジェクトのインスタンスに設定されていません」というエラーが発生し続ける

Answer 1

あなたの問題は、あなたが

public HomePage(IWebDriver driver) 
    { 
     Driver = driver; 
     Driver = (IWebDriver)ScenarioContext.Current["driver"]; 
     PageFactory.InitElements(Driver, this); 

     HeaderNavigation = new HeaderNavigation(Driver); 
     HomePageMenuBar = new HomePageMenuBar(Driver); 
    } 

私は

https://github.com/browserstack/specflow-browserstack/blob/master/SpecFlow-BrowserStack/BrowserStack.csを使用し、プライベートとしてIWebDriverを作るラインはあなたので、そこにある

に既存のドライバのインスタンスを渡すのではなく、新しいドライバ・インスタンスを作成することですそれを渡すことはできません。パブリックにして、それをページオブジェクトに渡します。

public MainPageObjects(BrowserStackDriver driver) 
    { 

     PageFactory.InitElements(driver.driver, this); 

    }
