测试用例从文件中导入数据：

 

设置文件信息包含webinfo和usrinfo、设计接口包括get_webinfo(路径名)和get_userinfo(配置文件路径名)
那么ele_dict = get_webinfo(path)、user_list = get_userinfo(path)

webinfo文件的：

url=https://www.baidu.com/
text_id=登录
userid=TANGRAM__PSP_10__userName
pwdid=TANGRAM__PSP_10__password
loginid=TANGRAM__PSP_10__submit
errorid=用户名或密码错误！

userinfo文件的：

uname=你的百度云账号 pwd=你的百度云密码
