如何拋出異常，當我打開兩個或三個窗口

Question

我有兩個或三個打開（在不同情況下）窗口，並試圖拋出異常開始下一個測試。
當我寫：

throw new RuntimeException("anything"); 

新彈出的窗口中顯示的文字：「您正在查看正在試圖關閉窗口的網頁是否要關閉此窗口」和腳本停止。

瀏覽器：Internet Explorer 8
我知道，當我嘗試關閉窗口時，此窗口會顯示。

OK，添加我的代碼：

//my methods 
public static boolean switchToWindowAboutTitle(WebDriver driver, String title){ 
     String currentWindow = driver.getWindowHandle(); 
     Set<String> availableWindows = driver.getWindowHandles(); 
     try{ 
     if(!availableWindows.isEmpty()){ 
      for(String windowId : availableWindows){ 
       String switchedTitle = driver.switchTo().window(windowId).getTitle(); 
       if(switchedTitle.equals(title) || switchedTitle.contains(title)) 
        return true; 
       else{ 
        driver.switchTo().window(currentWindow); 
       } 
      } 
     } 
     }catch(NoSuchWindowException ignore){ 
      return false; 
     } 
     return false; 
    } 

//my code: 

//my main window -- window title: "Main" 
driver.switchTo().defaultContent(); 
driver.switchTo().frame("Main"); 

//click on button which open new window 
driver.findElement(byDetermineButton).click(); 

//window title: "Authorize" 
switchToWindowAboutTitle(driver, "Authorize"); 

new WebDriverWait(driver, 180).until(ExpectedConditions.elementToBeClickable(byProduct)); 
driver.findElement(byProduct).click(); 

try { 
           Thread.sleep(10000); 
          } catch (InterruptedException e) { 
           // TODO Auto-generated catch block 
           e.printStackTrace(); 
          } 
System.out.println(driver.getWindwHandles().size());  //show 3 
//after click when window size == 3 I'd like throw exception because this means that my product isn't available --> this third window show information about it. 
if(driver.getWindowHandles().size() == 3){ 
    throw new RuntimeException("test"); 
} 

當我執行代碼：拋出新的RuntimeException（ 「測試」）; Internet Explorer show alert： 「您正在查看的網頁正試圖關閉窗口。 要關閉此窗口嗎？」我有兩個選擇：是或否。

爲什麼我不能扔異常:(
