Question

使用Selenium版本2.44和IE版本11.0.9600.17728

如果驱动程序构造函数因保护模式设置而失败，则EXE仍然在运行。

当一切正常时，似乎退出调用清理了事情，但由于驱动程序从未构建，因此无法使用。

当构造函数抛出异常时是否可以停止EXE？

import org.openqa.selenium.ie.InternetExplorerDriver;

public class SeleniumTest
{
    public static void main(String[] args)
    {
        System.setProperty("webdriver.ie.driver", "C:\\IEDriverServer_Win32_2.44.0.exe");

        try
        {
            InternetExplorerDriver driver = new InternetExplorerDriver();
            driver.get("http://www.google.com");
            Thread.sleep(10 * 1000);
            driver.quit();
        }
        catch (Exception e)
        {
            /*
             * To cause this, change the following IE settings:
             * 
             * On tab: Internet Options->Security
             * 
             * Make sure the four zones do not have the same value for "Enabled Protected Mode"
             */
            System.err.println("Failed making the driver");
            e.printStackTrace();
        }
        System.exit(0);
    }
}

运行上述代码时看到的输出：

Answer 1

即使测试捕获异常，驱动程序也会被实例化。当您尝试导航到url并且同时驱动程序已经实例化时，会发生异常。所以在catch块中调用quit，这将完成你想要的工作。

import org.openqa.selenium.ie.InternetExplorerDriver;

public class SeleniumTest
{
    public static void main(String[] args)
    {
        System.setProperty("webdriver.ie.driver", "C:\\IEDriverServer_Win32_2.44.0.exe");

        try
        {
            InternetExplorerDriver driver = new InternetExplorerDriver();
            driver.get("http://www.google.com");
            Thread.sleep(10 * 1000);
            driver.quit();
        }
        catch (Exception e)
        {
            /*
             * To cause this, change the following IE settings:
             * 
             * On tab: Internet Options->Security
             * 
             * Make sure the four zones do not have the same value for "Enabled Protected Mode"
             */
            driver.quit();
            System.err.println("Failed making the driver");
            e.printStackTrace();
        }
        System.exit(0);
    }
}

Answer 2

您可以将以下代码放入catch块中。

ThreadPool.QueueUserWorkItem

Selenium失败后，IEDriverServer可执行文件仍然存在
