Selenium webdriver退出,错误代码为135

Question

我是量角器的新手.尝试使用量角器运行Selenium测试时出现以下错误

我查看是否有其他进程正在侦听端口4444,但没有找到任何进程.我也用--standalone标志运行web驱动程序.

似乎selenium服务器没有运行http://127.0.0.1:4444/wd/hub.在运行量角器测试之前,必须使用以下命令启动selenium服务器.webdriver-manager start.启动服务器后,您的测试将执行而不会出现任何错误.

如果你不想手动启动selenium服务器,那么只需seleniumAddress:http://localhost:4444/wd/hub从你的conf.js中删除属性.
