第四天: Python接口测试框架
什么是框架
目前主流接口测试方案
框架类型
框架的分层与规划
框架分层
- 表示层: (用户界面)
- 业务逻辑层: (读取数据,配置并组装发送请求)+执行控制层(pytest)
- 数据层: (配置读取/数据读取/数据库连接/其他(log/email)
框架规划
- case: 测试用例目录
- user: (用户模块)
- case.py: 用例公共方法
- data: 数据文件目录
- test_user_data.xlsx: 测试用例数据文件
- conf: 配置文件目录
- report: pytest生成的报告保存路径
- log: log保存路径,按天生成log
- common: 公共方法目录
- config.py: 配置文件读取
- data.py: 数据文件读取
- db.py: 数据库连接
- log.py: 日志配置
- send_email.py: 发送邮件配置
框架实现
