小编Riv*_*Riv的帖子

嘿伙计们当我在java中编写webdriver测试时,我试图从textarea读取文本,并且出于某种原因,当我使用.getAttribute()时,我得到null

     WebElement text = wd.findElement(By.id("edit-pi-sample-geo-id"));

     String textagain = text.getAttribute("aaaa");

我想知道如何解决这个问题？

我试图在jenkins上将windows slave连接到linux master,我总是看到下面的错误.我已经尝试过以下链接提到的所有内容,但我仍然看到同样的错误.
