# samples样例默认不执行
本目录下的 ``*.py.sample`` **不会被** ``python tests/run_tests.py`` 收集。
复制为 ``tests/test_*.py``(去掉 ``.sample``)后,再按业务实现 service / golden 断言。

Service 层契约测试范式(示意)。
复制为真实技能后:
1. 将 ``from service.your_service import run`` 替换为实际模块与入口函数。
2. 用 ``FakeAdapter`` / 内存 stub 替代真实 ERP/TMS/WMS 等外呼。
3. 需要真实外网或真实 RPA 时,勿在本文件直接写死凭证;改用 ``tests/integration/*.sample`` + 环境开关。
