测试积点老人

安装好了以后在命令行运行Python，引入selenium库，如果没有报错则安装成功，使用.__version__可以查看安装的版本

1. C:\Users\whats>python
   
2. Python 2.7.12 |Anaconda custom (64-bit)| (default, Jun 29 2016, 11:07:13) [MSC v.1500 64 bit (AMD64)] on win32
   
3. Type "help", "copyright", "credits" or "license" for more information.
   
4. Anaconda is brought to you by Continuum Analytics.
   
5. Please check out: http://continuum.io/thanks and https://anaconda.org
   
6. >>>import selenium

使用火狐浏览器进行自动化测试，出现问题

1. from selenium import webdriver
   
2. 
   
3. brow = webdriver.Firefox()
   
4. Traceback (most recent call last):
   
5. File "<stdin>", line 1, in <module>
   
6. File "C:\Users\whats\Anaconda2\lib\site-packages\selenium\webdriver\firefox\webdriver.py", line 144, in __init__
   
7. self.service.start()
   
8. File "C:\Users\whats\Anaconda2\lib\site-packages\selenium\webdriver\common\service.py", line 81, in start
   
9. os.path.basename(self.path), self.start_error_message)
   
10. 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

1. from selenium import webdriver
   
2. from selenium.webdriver.common.keys import Keys
   
3. 
   
4. browser = webdriver.Firefox()
   
5. browser.get('http://www.baidu.com)
   
6. print browser.title #打印网页标题
   
7. browser.quit()
