Selenium在一台计算机上发生"UnreachableBrowserException/Address已在使用中"

Question

我有一个java webdriver驱动的selenium执行,它在列表上循环,在文本框中输入不同的信息并使用FirefoxDriver发送它.

在一台计算机上,相当可重复,在第10次或第11次迭代之后,召唤 findElement(By.id("mi4"))一次UnreachableBrowserException.

没有第三方程序在任何端口上侦听.但是,我使用两个FirefoxDriver实例,这意味着两个Firefox实例/ Windows并行打开,在Win7机器上没有任何问题,所描述的问题发生在Windows XP机器上.

我使用Firefox 13和selenium 2.24.1.

听起来你正在耗尽短暂的端口,因为你一遍又一遍地迭代.在Windows XP中,默认最大临时TCP端口数为5000.尝试按照此处 Microsoft KB文章中的分辨率增加限制.重启机器.这个解决方案对我有用.
