1.安装 
pip install pythium

1.基础层

用来存放driver以及初始化

from selenium import webdriver
from webdriver_manager.chrome import ChromeDriverManager
from .login_page import LoginPage
# pip install webdriver_manager

class BasePage(object):

    def __init__(self):
        # self.driver = webdriver.chrome(ChromeDriverManager().install())
        self.driver = webdriver.Chrome()
        self.driver.maximize_window()

    def open_url(self, url: str) -> None:
        self.driver.get(url)

    def quit_browser(self) -> None:
        self.driver.quit()

    def get_loginpage(self) :
        return LoginPage(self.driver)

3.对象层
用于存放界面元素定位和控件操作

import time
from pythium import find_by, Page
from selenium.webdriver.remote.webelement import WebElement

class LoginPage(Page):

    @find_by(xpath='//*[@id="search"]/form/div[2]/input')
    def input_ele(self) -> WebElement: ...

    @find_by(xpath='//*[@id="search"]/form/div[3]/input')
    def search_ele(self) -> WebElement: ...

    def run(self):
        time.sleep(1)
        self.input_ele().send_keys("selenium")
        time.sleep(2)
        self.search_ele().click()
        time.sleep(5)

4.操作层
封装好的功能用例模块，即测试用例的步骤

import time
from .base_page import BasePage

class LoginAction(object):

    def login(self):
        base_page = BasePage()
        base_page.open_url("https://www.hao123.com/")
        time.sleep(5)
        base_page.get_loginpage().run()

5.业务层
测试类，添加测试用例

import unittest
from .login_action import LoginAction

class TestLogin(unittest.TestCase):

    def test_search(self):
        LoginAction().login()

if __name__ == '__main__':
    unittest.main()
