mannual和adhoc模式比較

Manual vs. Adhoc

In the script above, we start the ChromeDriver server process when we create the WebDriver object and it is terminated when we call quit(). For a one-off script, that isn’t a problem, but this can waste a nontrivial amount of time for a large test suite that creates a ChromeDriver instance for each test. Luckily, we can manually start and stop the server ourselves, and it only requires a few changes to the script above.

說的在使用selenium+chromeheadless做自動化測試時候，如果測試用例數量大，給每個測試用例啟動一個瀏覽器要話費更多的時間。

#coding=utf8
import os,traceback
from selenium import webdriver
from selenium.webdriver.common.keys import Keys
from selenium.webdriver.chrome.options import Options

service = webdriver.chrome.service.Service('/home/xxxx/Downloads/phantomjs-2.1.1-linux-x86_64/bin/chromedriver')
service.start()
class ChromeHeadless(object):

def __init__(self):

chrome_options = Options()
chrome_options.add_argument("--headless")
chrome_options.add_argument('--disable-gpu')
chrome_options.add_argument('--disable-images')
chrome_options.add_argument('--disable-plugins')
chrome_options.binary_location = '/opt/google/chrome/chrome'
#prefs = {"profile.managed_default_content_settings.images": 2} # 關圖片
#chrome_options.add_experimental_option("prefs", prefs)
self.chrome_options=chrome_options
self.driver = webdriver.Remote(service.service_url,desired_capabilities=self.chrome_options.to_capabilities())
self.driver.set_page_load_timeout(120)

def fun(self,url):

try:
proxy_http_list = list(r.smembers('kuaidaili:http')) + list(r.smembers('zhima'))
pr=random.choice(proxy_http_list)
self.chrome_options.add_argument('--proxy-server=%s'%pr) #設置代理
self.driver.start_session(self.chrome_options.to_capabilities())
#print self.driver.session_id
self.driver.get(url)

except Exception,e:

print '\033[7;32;0m%s\033[0m' %traceback.format_exc()
