七、common下的log_utils.py 封装

八、common下的config_utils.py的封装


配置文件的编写：

对配置文件的读取封装：

import configparser

current_path = os.path.dirname(__file__)
cfgpath = os.path.join(current_path, "../conf/local_config.ini")
print(cfgpath)


class ConfigUtils:
  def __init__(self,config_path=cfgpath):

    return report_file_path


if __name__=='__main__':
  report_path = RunCase().run()
  EmailUtils(open(report_path, 'rb').read(), report_path).send_mail()


十、common下的email_utils.py 封装


import os
import smtplib
from email.mime.text import MIMEText
from email.mime.multipart import MIMEMultipart
from common.config_utils import config

class EmailUtils():
  def __init__(self,smtp_body,smtp_attch_path=None):

if __name__=='__main__':
  html_path = os.path.dirname(__file__) + '/../test_reports/接口自动化测试报告V1.1/接口自动化测试报告V1.1.html'
  EmailUtils('<h3 align="center">自动化测试报告</h3>',html_path).send_mail()
