通过不同的浏览器来启动不同的线程.py

from threading import Threadfrom selenium import webdriverfrom time import ctime,sleep#测试用例def test_baidu(browser,search):    print("start:%s" % ctime())    print("browser:%s" % browser)    if browser == "ie":        driver = webdriver.Ie()    elif browser == "chrome":        driver = webdriver.Chrome()    elif browser == "ff":        driver = webdriver.Firefox()    else:        print("browser参数有误,只能为ie、ff、chrome")    driver.get("http://www.baidu.com")    driver.find_element_by_id("kw").send_keys(search)    driver.find_element_by_id("su").click()    sleep(2)    driver.quit()if __name__ == ‘__main__‘:    #启动参数：    lists = {"chrome":"threading","ie":"webdriver","ff":"python"}    threads = []    files = range(len(lists))    #创建线程    for browser,search in lists.items():        t = Thread(target=test_baidu,args=(browser,search))        threads.append(t)    #启动线程    for t in files:        threads[t].start()    for t in files:        threads[t].join()    print("end:%s" % ctime())
