selenium4.x 之POM概况

Page Object Mpde

一、基类

basePage

import logging
import time
from selenium import webdriver
from selenium.webdriver.common.by import By
from selenium.webdriver.support.wait import WebDriverWait
logger = logging.getLogger("PO")


class BasePage:
    """poge的基类"""

    def __init__(self, driver: webdriver.Chrome):
        self._driver = driver
        self._wait = WebDriverWait(driver, 10)   # 自动等待
        logger.info("PO实例化成功")

    def __getattr__(self, item):
        key = f"_loc_{item}"
        if hasattr(self, key):
            xpath = getattr(self, key)
            return self.get_element(xpath)
        raise AttributeError(f'元素不存在:{item}')

    def get_element(self, xpath):
        logger.info("正在进行元素定位")
        el = self._wait.until(lambda x: self._driver.find_element(By.XPATH, xpath))
        logger.info("元素定位成功")
        return el

    # alert弹窗
    def alert(self):
        time.sleep()

        # alert = driver.switch_to.alert
        def _a():
            return self._driver.switch_to.alert  # 可能会失败，可能会成功

        alert = self._wait.until(_a)
        alert.accept()
    
    # 系统信息
    def get_msg(self):
        time.sleep(0.5)  # 等待-0.5秒
        el = self._driver.find_element(By.XPATH, "//p[@class='prompt-msg']")
        return el.text

二、页面

page：可以讲属性和方法分开

属性（元素）和方法（元素的操作）

class LoginPage(BasePage):
    _loc_code = ('//div/ul/li[@class="account-tab-account"]')
    _loc_username = ('//input[@id="username"]')
    _loc_password = ('//input[@id="password"]')

    def login(self, username, password):
        self.code.click()
        self.username.send_keys(username)
        self.password.send_keys(password)

元素可单独封装

三、测试用例

def test_00():
    driver = get_webdriver()
    driver.get("https://accounts.douban.com/passport/login")
    page = LoginPage(driver)
    page.login("12255", "123456")
