Question

有没有办法查看是否所有浏览器窗口都已关闭？我看到如果你在WebDriver上调用driver.quit（）或driver.close（），sessionId就变为null。有没有办法检查？

我不想调用已关闭或退出的驱动程序，因为它会抛出WebDriverException。所以我想在继续之前检查浏览器的状态。

Answer 1

只需设置

driver=null;

每次退出浏览器而不是检查

if (browser!=null){
  //Attention: this comand is not supported
  //as far as i know ;)
  driver.doSomething();
}

或

try{


}catch (NullPointerException e)

    e.printStackTrace();
    System.err.print"DAMN";
}

或收到NullPointerException;）

public bool InstanceExist
    {
        get
        {
            if (Instance != null)
            {
                try
                {
                    return (Instance.WindowHandles != null); // allways returns true if browser instance exist or thrown error
                }
                catch (Exception e)
                {
                    return false;
                    // means that browser was closed by user
                }
            }
            return false; // means that it wasn't created yet or was closed by developer programmally
        }
    }

你需要检查3种情况：

驱动程序未创建
驱动程序已由开发人员关闭
浏览器已被用户关闭，但driwer实例仍然存在

使用此代码检查所有这些情况。

实际上，当浏览器窗口消失时调用getWindowHandles会引发＆＃34; UnreachableBrowserException＆＃34;。

您必须将调用放入try-catch块并处理该错误。实际上，这是捕获意外浏览器窗口关闭的唯一已知的WORKING workournd。我在配置类中有一个静态方法来处理我的驱动程序：我重启我的浏览器：

protected static void loadPages() {

    if (driver == null || driver.toString().contains("null"))  { //null refers to an missing session id

            driver = new FirefoxDriver();

        //load all my page objects like
        loginpage = new LoginPage(driver);
        //....
        //....

        }
try {
        if (driver.getWindowHandles() == null || driver.getWindowHandles().isEmpty()){ //will cause an UnreachableBrowserException if the browser really is not avalable. 
            try { //you actually dont need this try catch block 
                driver.quit();
            } catch (Exception e) {
                System.err.println("Quitting levtover driver did not work.");
            }
            driver = null; //you have to set the driver to null
            loadPages();
            }
    } catch (UnreachableBrowserException ube) {
        driver = null; //like above set to null to make sure no driver left
    }

}

现在，你的当前测试将失败，但你将能够继续其余的测试。

我认为检测所有窗户是否关闭的最简洁方法就像：

boolean allWindowsClosed = webDriver.getWindowHandles().isEmpty();

getWindowHandles为所有打开的窗口返回一组窗口句柄 - 请参阅http://selenium.googlecode.com/git/docs/api/java/org/openqa/selenium/WebDriver.html#getWindowHandles()

在 C# 中

Total_health = 0

class Rover:

    self.xray = xray

Rover = Rover(False, False, False, False, False, False, False, 100, False, False, False)
Rover.battery = 100

def lines():
  print("_____________________________________________")
