org.openqa.selenium.NoSuchWindowException：無法獲取瀏覽器

Question

我登錄到我的應用程序（IE瀏覽器）。在主頁上，它具有消費者鏈接。我點擊它..它會打開另一個窗口..輸入消費者ID（僅限必填字段）並保存。它正在得到保存。

現在如果我想查看保存的消費者。我需要關閉窗口並需要將控件傳輸到主頁。關閉窗口後我正在嘗試driver.switchTo.defaultContent()。但它不會改變控制。返回下面的錯誤..

異常：

Exception in thread "main" org.openqa.selenium.NoSuchWindowException: Unable to get browser (WARNING: The server did not provide any stacktrace information)

嘗試切換之前進行存儲處理程序名稱。

public static void main(String[] args) throws IOException, InterruptedException { 
     // TODO Auto-generated method stub 
     File file = new File("IEDriverServer.exe"); 
     System.setProperty("webdriver.ie.driver", file.getAbsolutePath()); 
     WebDriver driver = new InternetExplorerDriver();   
     driver.get("http://xx.xxx.xxx.xx/mysuite/Login.aspx"); 
     driver.findElement(By.id("txtUser")).sendKeys("administrator"); 
     driver.findElement(By.id("txtPwd")).sendKeys("password"); 
     driver.findElement(By.id("cmdLogin")).click();  
     //Click Add customer (customer child window opens) 
     driver.findElement(By.linkText("Add Customer")).click(); 

     //Store before switch  
     String mainHandle= driver.getWindowHandle(); 

     driver.switchTo().window("Customer"); 

     //Enter Customer ID and Save 
     driver.findElement(By.id("txtCode")).sendKeys("1234"); 
     driver.findElement(By.id("cmdPageSave")).click(); 
       //Close the child window 
     driver.findElement(By.id("cmdPageClose")).click(); 
     //swith back to parent window 

     driver.switchTo().window(mainHandle); 

     Thread.sleep(3000); 
     driver.findElement(By.linkText("All customers")).click(); 

    }
