Posted 2020-12-25 Owen_ET

问题描述：执行多个用例的时候，会抛出异常：

Traceback (most recent call last):
  File "F:DemopomGisStugis	est_casemodelsmytest.py", line 9, in setUp
    self.driver = browser()
  File "F:DemopomGisStugis	est_casemodelsdriver.py", line 4, in browser
    return webdriver.Chrome()
  File "F:软件python3.6.1libsite-packagesseleniumwebdriverchromewebdriver.py", line 61, in __init__
    self.service.start()

    res = inst._internal_poll(_deadstate=sys.maxsize)

    if _WaitForSingleObject(self._handle, 0) == _WAIT_OBJECT_0:
OSError: [WinError 6] 句柄无效。

问题分析：

经查询得知，是因为后台有多个chromedriver.exe被启动，应该关闭它，自测得知最多只能打开三个测试用例的的浏览器

解决办法：

利用quit（）方法关闭浏览器，不能使用close（）方法关闭。
