Python+selenium 【第十一章】封装底层页面操作类
作者：互联网
本章题要:
本章节主要是封装底层操作类,将页面操作都封装到一个操作中,并结合我们之前的element_excel_utils中的部分信息结合使用
- 实现demo

import time
from selenium import webdriver
from selenium.webdriver.common.by import By
class DemoBasePage:
def __init__(self, driver):
self.driver = driver
def open_url(self, url):
self.driver.get(url)
def click(self, element_info):
＃＊号是解包
self.driver.find_element(*element_info).click()
def send_keys(self, element_info, text):
self.driver.find_element(*element_info).send_keys(text)
if __name__ == '__main__':
driver = webdriver.Chrome()
db = DemoBasePage(driver)
db.open_url("http://www.baidu.com")
driver.implicitly_wait(10)
db.send_keys((By.XPATH,'//*[@id="kw"]'),"测试一下")
time.sleep(2)
db.click((By.XPATH,'//*[@id="su"]'))
在此我们先了解一下匿名函数的用法,匿名函数有哪些优点?
- 不用取名称，因为给函数取名是比较头疼的一件事，特别是函数比较多的时候
- 可以直接在使用的地方定义，如果需要修改，直接找到修改即可，方便以后代码的维护工作
- 语法结构简单，不用使用def 函数名(参数名):这种方式定义，直接使用lambda 参数:返回值 定义即可
举例：比方说，我要写一个函数用于两个数相乘

- 在common文件夹下新建base_page.py 将写好的代码copy进去

基本上的封装方式就是这样的，大家可以自己根据项目的情况封装一些使用的方法
