運行下面的代碼時出現配置錯誤。因此，我無法做進一步的行動。有人可以幫助我運行腳本。通過TestNg運行代碼時出錯

你犯了一個錯誤。

WebDriver driver;是一個類變量，即類的任何方法都可以使用它。

在@BeforeMethod中，你寫了一行： WebDriver driver = new ChromeDriver（options）;。請將其替換爲 driver = new ChromeDriver（options）;

您正在創建Webdriver類型的單獨對象，類變量驅動程序的值仍爲「null」，因此您將得到Null指針異常。

你的回答與@vijayjawale不同嗎？謝謝 – DebanjanB

是的，你是對的。答案沒有什麼不同。當我開始寫答案時，它不在那裏。 – Monika

在你beforeMethod你有局部變量司機符合

webdriver的驅動程序=新ChromeDriver（選件）;

它必須是

driver = new ChromeDriver(options);

方法將是如下：

@BeforeMethod 
     public void beforeMethod() { 
    System.setProperty("webdriver.chrome.driver","C:\\Chrome\\chromedriver.exe"); 
      ChromeOptions options = new ChromeOptions(); 
      Map<String, Object> prefs = new HashMap<String, Object>(); 
      prefs.put("credentials_enable_service", false); 
      prefs.put("password_manager_enabled", false); 
      options.setExperimentalOption("prefs", prefs); 
      options.addArguments("start-maximized"); 
      options.addArguments("disable-infobars"); 
      driver = new ChromeDriver(options); 
     }
