Phase 5 Sprint 5.0-5.1 Callback Dispatcher 單元測試
|
||
======================================================
|
||
建立: 2026-04-14 台北深夜 Claude Sonnet 4.6
|
||
|
||
覆蓋:
|
||
- callback_action_spec.yaml 載入正確性
|
||
- 24 個 action 都能解析
|
||
- 模板變數替換（_resolve_template）
|
||
- Context lookup（labels.instance / signals[0].alert_name）
|
||
- dispatch_action 骨架（Sprint 5.0 階段返回 stub）
|
||
|
||
🔴 遵循「禁止 Mock 測試鐵律」: 用真實 spec registry，不 mock。
