Python多线程应用于自动化测试操作示例

  driver.find_element_by_id("su").click()
  sleep(2)
  driver.quit()

  #定义字典存放test_baidu函数的参数

  #创建空列表存放线程

  file = range(len(dicts))
  #启动线程
  for i in file:

  #守护线程

'''
在不同主机、不同浏览器同时执行测试用例，多线程；
利用Selenium Girl提供分布式执行测试用例；
先启动Selenium server，这里分别在本地主机启动一个hub和一个node，在其他主机（虚拟机）启动一个node。
