'3.4.3'
使用火狐浏览器进行自动化测试，出现问题
from selenium import webdriver
brow = webdriver.Firefox()
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
File "C:\Users\whats\Anaconda2\lib\site-packages\selenium\webdriver\firefox\webdriver.py", line 144, in __init__
self.service.start()
File "C:\Users\whats\Anaconda2\lib\site-packages\selenium\webdriver\common\service.py", line 81, in start
os.path.basename(self.path), self.start_error_message)
selenium.common.exceptions.WebDriverException: Message: 'geckodriver' executable needs to be in PATH.
从错误信息知道需要安装’geckodriver’并且设置环境变量
下载geckodriver
http://download.csdn.net/detail/xiaojiawen/9772341
根据自己的电脑选择x86或者x64的进行解压
解压后得到geckodriver.exe，找到Python的安装目录，进入Scripts文件夹，将解压后的文件复制到Scripts文件夹
下一步进行系统环境变量的配置
->右键此电脑->属性->高级系统设置->环境变量
新建系统变量添加以下信息
变量名：geckodriver
输入以下代码进行测试，成功
from selenium import webdriver
from selenium.webdriver.common.keys import Keys
browser = webdriver.Firefox()
browser.get('http://www.baidu.com)
print browser.title #打印网页标题
browser.quit()
