Selenium（Python web测试工具）基本用法详解

pip install selenium

from selenium.webdriver import Chrome
from selenium.webdriver.common.keys import Keys
# 创建Chrome WebDriver实例，此路径为驱动程序的路径
driver = Chrome("C:\Program Files (x86)\Google\Chrome\Application\chromedriver.exe")
# 加载URL网页
driver.get("http://www.baidu.com/")
# 判断标题中是否包含该字符串
assert "百度一下" in driver.title
# 查找id=kw的节点
element = driver.find_element_by_id("kw")
# 清空原有的输入，输入python进行搜索
element.clear()
element.send_keys("python")
element.send_keys(Keys.RETURN)
# 判断是否有结果返回
assert "No results found." not in driver.page_source
# 关闭当前标签，也可以使用quit()关闭浏览器
driver.close()

import unittest
from selenium.webdriver import Chrome
from selenium.webdriver.common.keys import Keys
# 继承至TestCase，表示这是一个测试用例类
class BaiduCase(unittest.TestCase):
  # 初始化的一部分
  def setUp(self):
    self.driver = Chrome("C:\Program Files (x86)\Google\Chrome\Application\chromedriver.exe")
  # 测试用例方法，名称可以自定义，方法名称始终以test开头
  def test_serch(self):
    self.driver.get("https://www.baidu.com/")
    assert "百度一下" in self.driver.title
    element = self.driver.find_element_by_id("kw")
    element.clear()
    element.send_keys("python")
    element.send_keys(Keys.RETURN)
    assert "No results found." not in self.driver.page_source
  # 在执行完各种测试用例方法之后会执行，为一个清理操作
  def tearDown(self):
    self.driver.close()
if __name__ == "__main__":
  unittest.main()
