       selenium是一个用于web应用程序测试的工具。selenium测试直接运行在浏览器中，就像真正的用户在操作一样。本文主要讲述的是web测试中selenium 3使用的问题集以及解决方案。

1. 无法启动FireFox--geckodriver

运行 driver=webdriver.Firefox()

运行报错：
Exception AttributeError: "'Service' object has no attribute 'process'" in d method Service.__del__ of t 0x028940B0>> ignored

selenium.common.exceptions.WebDriverException: Message: 'geckodriver' executabl needs to be in PATH.
