# T045 — 搜尋目標與關聯性回歸
|
|||
|
|
|
|||
|
|
> Status: `done`
|
|||
|
|
> Milestone: `M4`
|
|||
|
|
> Est. change: `~200 test lines`
|
|||
|
|
|
|||
|
|
## Goal
|
|||
|
|
|
|||
|
|
完成後，搜尋補量、強關聯、去重、不足原因與 score 排序都有端到端 usecase 測試。
|
|||
|
|
|
|||
|
|
## Depends on
|
|||
|
|
|
|||
|
|
- T044
|
|||
|
|
|
|||
|
|
## Inputs
|
|||
|
|
|
|||
|
|
- 讀取 / 依賴：
|
|||
|
|
- 檔案：`apps/backend/internal/module/scout/usecase/testdata/topic_quality_cases.json`
|
|||
|
|
- 既有能力 / API：MemoryStore、fake Provider/Crawler、RunScan pipeline
|
|||
|
|
- Spec 段落：§9 #1–#11、§9 #17
|
|||
|
|
|
|||
|
|
## Outputs
|
|||
|
|
|
|||
|
|
### 程式變更（預期路徑）
|
|||
|
|
|
|||
|
|
| 路徑 | 動作 | 說明 |
|
|||
|
|
|------|------|------|
|
|||
|
|
| `apps/backend/internal/module/scout/usecase/search_quality_integration_test.go` | add | 覆蓋 target、shortfall、multi-source、history dedupe、time order。 |
|
|||
|
|
| `apps/backend/internal/module/scout/usecase/testdata/topic_quality_cases.json` | edit | 補齊關聯性案例與標註。 |
|
|||
|
|
|
|||
|
|
### 行為變更
|
|||
|
|
|
|||
|
|
- 無新增產品邏輯；固定 M4 完成行為。
|
|||
|
|
|
|||
|
|
### API / 契約（若有）
|
|||
|
|
|
|||
|
|
- 測試確認 eligible_count 等於公開 result total，shortfall reasons 非空且可解釋。
|
|||
|
|
|
|||
|
|
## Out of scope
|
|||
|
|
|
|||
|
|
- 不以真 provider、真 Mongo 或網路作成功條件。
|
|||
|
|
|
|||
|
|
## Acceptance
|
|||
|
|
|
|||
|
|
- [x] Spec #1–#11 對應案例全部通過，existing provider/demand 測試不回歸。
|
|||
|
|
- [x] 指令：
|
|||
|
|
|
|||
|
|
```bash
|
|||
|
|
cd apps/backend && go test ./internal/module/scout/... -count=1
|
|||
|
|
```
|
|||
|
|
|
|||
|
|
驗收結果：整合回歸涵蓋 fixtures、eligible-driven 補量與 320 cap、shortfall reason、historical canonical dedupe、run 原子 publish 及跨頁 score／同分時間排序；Scout module 全測試通過。
|
|||
|
