HttpRunner3.X - .env环境变量文件的运用

一、前言

在自动化测试中，有时需要借助环境变量实现某些特定的目的，常见的场景包括：

• 切换测试环境
• 切换测试配置
• 存储敏感数据（从信息安全的角度出发）

二、.env文件设置环境变量

base_url=https://qa1-xxx.cn
host=qa1-api.xxng.cn
username=李白
password=123456

三、Pytest脚本引用变量案例

在 HttpRunner 3.x版本中内置了函数 ENV 函数读取环境变量的值，引用环境变量使用ENV函数 ${ENV(keyname)}

注：.env 文件必须放到项目根目录(debugtalk.py同一层级)
