selenium+python自动化测试（二）对浏览器的简单操作

1.最大化

maximize_window

 1 # coding = utf-8
 2 
 3 from selenium import webdriver
 4 chromedriver = "C:Program Files (x86)GoogleChromeApplicationchromedriver"
 5 browser = webdriver.Chrome(chromedriver)
 6 
 7 browser.get('http:\www.baidu.com')
 8 browser.maximize_window()
 9 browser.find_element_by_id('kw').send_keys('selenium')
10 browser.find_element_by_id('su').click()
11 
12 browser.quit()

发现运行时候报错了：

selenium.common.exceptions.WebDriverException: Message: disconnected: unable to connect to renderer
(Session info: chrome=62.0.3202.94)
(Driver info: chromedriver=2.30.477700 (0057494ad8732195794a7b32078424f92a5fce41),platform=Windows NT 6.1.7601 SP1 x86_64)

就是chrome和chromedriver版本不对应。关键词检索了下，发现的原因。然后下载了个更新的版本

http://chromedriver.storage.googleapis.com/index.html?path=2.34/

替换下就运行OK了

2.前进和后退

 1 rom selenium import webdriver
 2 import time
 3 chromedriver = "C:Program Files (x86)GoogleChromeApplicationchromedriver"
 4 browser = webdriver.Chrome(chromedriver)
 5 first_url = 'http:\www.baidu.com'
 6 second_url = 'http:\news.baidu.com'
 7 browser.get(first_url)
 8 browser.get(second_url)
 9 browser.back()
10 browser.maximize_window()
11 browser.forward()
12 browser.back()
13 time.sleep(5)
14 browser.set_window_size(480, 800)
15 browser.quit()
