selenium+pthon之一----环境搭建与脚本实例
一、安装selenium的环境
1.如何安装
(1)在cmd窗口输入安装指令:pip install selenium,直到安装成功(安装目录在E:\python\Lib\site-packages 所有selenium开头的文件,python所有的第三方工具都是在这个目录里)。
(2)验证:
>python
>from selenium import webdriver
>webdriver.Firefox()
确保电脑上安装了Firefox浏览器,如果能正常启动Firefox则说明安装成功。
(3)下载相应的浏览器驱动放到python根目录
(4)查看selenium版本号:pip show selenium
2.执行了2个实例:
(1)打开某个网页并查找内容
from selenium import webdriver
from selenium.webdriver.common.keys import Keys
driver = webdriver.Firefox()
driver.get("http://www.python.org")
assert "Python" in driver.title
elem = driver.find_element_by_name("q")
print(elem)
elem.clear()
elem.send_keys("pycon")
elem.send_keys(Keys.RETURN)
assert "No results found." not in driver.page_source
driver.close()
(2)使用unittest框架执行用例
import unittest
from selenium import webdriver
from selenium.webdriver.common.keys import Keys
class PythonOrgSearch(unittest.TestCase):
def setUp(self):
self.driver = webdriver.Firefox()
def test_search_in_python_org(self):
driver = self.driver
driver.get("http://www.python.org")
self.assertIn("Python",driver.title)
elem = driver.find_element_by_name("q")
elem.send_keys("pycon")
elem.send_keys(Keys.RETURN)
assert "NO results found." not in driver.page_source
def tearDown(self):
self.driver.close()
if __name__ == "__main__":
unittest.main()
