第八批模块单测 (零外部依赖, 不连库不触网)
|
||
==========================================
|
||
运行: 在 tradingSystem 仓库根目录执行 python scripts/test_batch8_units.py
|
||
覆盖: 上游榜单的版本比对 (app/core/plan_diff.py) —— 名册与指纹、三种比对语义、
|
||
进出榜的尾部闸、档位升降与券商覆盖翻转、名次跳变、持仓票视图。
|
||
|
||
这一批的重点不是"能不能算出差异", 而是**不报假变化**: 榜单是按 top 截断过的, 尾部的进出
|
||
是截断噪音而不是上游观点变化。假警报天天响, 提示就等于没有 —— 与 `_capped` 治的是同一个病。
