50. Page Object模式 - 2 元素定位与用例分离

上例，以下两句放到类里面，还是无法给其它文件调用。
 news = (By.CSS_SELECTOR, 'a[href="http://news.baidu.com"]')
 button = (By.ID, 'su')

新建一个page文件夹，用于存放元素定位的内容，此时代码结构

project > page > page_baidu.py
project > PO > test_baidu.py
project > PO >  conftest.py

# project > page > page_baidu.py
from selenium import webdriver
from selenium.webdriver.common.by import By
from base.base_page import BasePage
from utils.log_util import logger


class PageBaidu(BasePage):
    # 新闻
    news = (By.CSS_SELECTOR, 'a[href="http://news.baidu.com"]')
    # 百度一下按钮
    button = (By.ID, 'su')
    # 百度输入框
    # input = (By.ID, 'kw')
    # # 帮助
    # help = (By.CSS_SELECTOR, 'a[href="//help.baidu.com"]')
    # # 更多
    # more = (By.XPATH, '//*[@id="s-top-left"]/div/a')
    #
    # def search_keyword(self, keyword):
    #     logger.info("查找元素并输入内容")
    #     self.driver.find_element(*self.input).send_keys(keyword)
    #     logger.info("点击按钮")
