　　Selenium WebDriver is often used as a basis for testing web applications. Here is a simple example uisng Python’s standard unittest library:

import unittest
from selenium import webdriver
from selenium.webdriver.common.keys import Keys

#该测试类继承自 unittest.TestCase
class PythonOrgSearch(unittest.TestCase):

    def setUp(self):
        self.driver = webdriver.Chrome()

    def test_search(self):
        driver = self.driver
        driver.get("http://www.taobao.com")
        elem = driver.find_element_by_id("q")
        elem.send_keys("python")
        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()
