几种PC端driver的效率比较：
from selenium import webdriver import time drivers = ['HtmlUnit', 'PhantomJS', 'Chrome', 'FF', 'IE'] dervers_time = { 'HtmlUnit' : 0, 'PhantomJS' : 0, 'Chrome' : 0, 'FF' : 0, 'IE' : 0, } times = 50 def run_with_Chrome(): common_step(webdriver.Chrome()) def run_with_FF(): common_step(webdriver.Firefox()) def run_with_IE(): common_step(webdriver.Ie()) def run_with_PhantomJS(): common_step(webdriver.PhantomJS(executable_path=r'C:\Python27\Scripts\phantomjs.exe')) def run_with_HtmlUnit(): driver = webdriver.Remote("http://localhost:4444/wd/hub", desired_capabilities=webdriver.DesiredCapabilities.HTMLUNIT) common_step(driver) def common_step(driver): driver.get('http://www.baidu.com') ele = driver.find_element_by_id('su') print ele.get_attribute('value') driver.quit() for i in range(times): print '=============Times %s============' % i for driver in drivers: start = time.time() print start eval('run_with_%s()'%driver) end = time.time() print end elapse_time = end-start dervers_time[driver] += elapse_time print 'elapse for %s:%s' % (driver, elapse_time) for k,v in dervers_time.items(): print 'avg elapse for %s in %s times:%s' % (k, times, v/times) |
得出的结果：
最快的依次是htmlunit、PhantomJS、chrome、ie、ff
