+"""全量路由回归测试：启动后遍历所有 API 路由发请求，抓 500/异常。
+
+用法（项目根目录）：
+    .venv/bin/python scripts/regression_test.py
+
+设计：
+  - 用 Flask test_client（不占用 18050，不影响运行中的服务）
+  - GET 路由全量请求（路径参数自动替换）；流式/二进制接口跳过
+  - 写操作（POST/PUT/DELETE）发空 body 探测：期望 400/403/404（参数校验），
+    返回 500 = 代码缺陷（import 遗漏/引用错误），立即报出
+  - 关键业务 POST 用真实参数验证（亮屏/剪贴板/测试步骤/设备池增删）
+  - 退出码：有失败返回 1（可接入检查流程）
+
+背景：web/ 蓝图拆分后多次出现 import 遗漏导致接口 500（ADB_PATH/_log/常量等），
+每次都是线上报错才暴露。此脚本让这类问题在改动后 30 秒内现形。
