转载一篇文章，为Selenium/PhantomJS做准备

• PhantomJS 无浏览器操作
• Selenium启动浏览器操作

phantomjs使用

from selenium import webdriver
  driver = webdriver.PhantomJS()
  driver.get("http://www.baidu.com")
  data = driver.title
  print data

senelium 简单使用

Remote Selenium Server

from selenium import webdriver
from selenium.webdriver.common.desired_capabilities import DesiredCapabilities
driver = webdriver.Remote(
  command_executor='http://192.168.1.3:4444/wd/hub',
  desired_capabilities={'browserName': 'PhantomJS',
                                  'version': '2',
                                  'javascriptEnabled': True})
driver = webdriver.Remote(
   command_executor='http://192.168.1.3:4444/wd/hub',
   desired_capabilities=DesiredCapabilities.PHANTOMJS)
driver.get("http://www.baidu.com")
data = driver.title
print data

PhantomJS和Firefox速度对比：

import unittest
from selenium import webdriver
import time
class TestThree(unittest.TestCase):
 
    def setUp(self):
        self.startTime = time.time()
 
    def test_url_fire(self):
        self.driver = webdriver.Firefox()
        self.driver.get("http://www.qq.com")
        self.driver.quit()
 
    def test_url_phantom(self):
        self.driver = webdriver.PhantomJS()
        self.driver.get("http://www.qq.com")
        self.driver.quit()
 
    def tearDown(self):
        t = time.time() - self.startTime
        print "%s: %.3f" % (self.id(), t)
        self.driver.quit
 
if __name__ == '__main__':
    suite = unittest.TestLoader().loadTestsFromTestCase(TestThree)
    unittest.TextTestRunner(verbosity=0).run(suite)
