"""conftest — 模块化 API 接口测试共享 fixture。
|
||
|
||
提供:
|
||
- test_client: FastAPI TestClient 实例 (session 级复用)
|
||
- assert_route: 验证接口路由存在 (status_code != 404)
|
||
|
||
注意: 本 conftest 强制 DATABASE_TYPE=sqlite + mock Redis，仅作用于 backend/tests/ 目录。
|
||
backend/scripts/ 下的 test_bre_analysis_*_tc.py 是独立进程的真实 PG16+Redis 套件
|
||
（由 tests/test_stat_analysis_tc.py 以 subprocess 调用），此处用 collect_ignore_glob
|
||
排除，避免 pytest 收集时 import 它们污染 sqlite 环境。
