python3+selenium框架设计04-封装测试基类
在完成了日志类封装之后，那我们就要对测试基类进行实现，在其中对一些请求再次封装，在项目下新建一个framework文件夹，在文件夹下新建Base_Page.py文件，这是用来写测试基类的文件。在项目下新建screenshots文件件，用来存放截图。项目结构如下。
具体怎么封装还是要看被测试需要什么，只能提供一个大致思路，我项目能用的封装，你项目并不一定能用
测试基类的思路就是把所有能公用的方法全部封装，并加上日志输出。报错截图等。
看下Base_Page.py下具体代码
from Logs.log import log1
from selenium.common.exceptions import NoSuchElementException
import getcwd
import os
import time
class BasePage:
"""测试基类"""

self.driver = driver

time.sleep(secondes)
log1.info('暂停%d秒' % secondes)

"""截图"""
path = os.path.join(getcwd.get_cwd(), 'screenshots/') # 拼接截图保存路径
rq = time.strftime('%Y%m%d%H%M', time.localtime(time.time())) # 按格式获取当前时间
screen_name = path + rq + '.png' # 拼接截图文件名
# noinspection PyBroadException
try:
self.driver.get_screenshot_as_file(screen_name)
log1.info("截图保存成功")

def get_title(self):

log1.info('当前窗口的title是:%s' % title)
return title
def my_quit(self):

接下来测试一下封装的代码
在test_base.py写如下代码并运行
