Question

我正在尝试运行从Selenium IDE导出的Junit测试用例.我超越了异常.我正在使用Windows XP,Firefox 20.0.1,并使用selenium-server-standalone-2.28.0.jar.Upon运行,打开一个空白的Firefox窗口.当我关闭该窗口时,我在控制台中得到以下异常

Answer 1

您的Selenium版本可能与您的Firefox版本不兼容.尝试安装较旧的Firefox版本.

1. 在安装和旧版本之前,请进入Firefox并关闭自动更新选项.

   Firefox - >选项 - >选项 - >高级 - >更新 - >检查更新,但让我选择安装它们

2. 到这里安装和旧版本. https://ftp.mozilla.org/pub/mozilla.org/firefox/releases/

   您不必卸载Firefox,只需安装要安装的版本即可.在获得正确的版本之前,您可能需要尝试几个版本.
