coverage
[UDS] Analyze code-level test coverage across the eight-dimension framework and recommend which gaps to close. Use when: coverage percentages look healthy but defects still ship, judging test completeness beyond line percentage, setting coverage targets. Not for: requirement-level AC-to-test traceability — use /ac-coverage; writing the missing tests — use /tdd or /spec-derive. Keywords: test coverage, eight dimensions, line coverage, branch coverage, test quality, 測試覆蓋率, 八維度, 測試完整性.

# Test Coverage Assistant | 測試覆蓋率助手
Analyze test coverage across multiple dimensions and provide actionable recommendations.
多維度分析測試覆蓋率並提供可執行的建議。
> **Related**: For requirement-level coverage (which AC have tests?), use `/ac-coverage` instead. This skill (`/coverage`) focuses on code-level coverage (lines, branches, functions).
>
> **相關**：如需需求層級覆蓋率（哪些 AC 有對應測試？），請改用 `/ac-coverage`。此技能（`/coverage`）專注於程式碼層級覆蓋率。
## Coverage Dimensions | 覆蓋率維度
| Dimension | What it Measures | 測量內容 |
|-----------|------------------|----------|
| **Line** | Lines of code executed | 執行的程式碼行數 |
| **Branch** | Decision paths taken | 決策路徑覆蓋 |
| **Function** | Functions called | 呼叫的函數 |
| **Statement** | Statements executed | 執行的陳述式 |
## 8-Dimension Framework | 八維度框架
1. **Code Coverage** - Lines, branches, functions
2. **Requirement Coverage** - All requirements have tests
3. **Risk Coverage** - High-risk areas prioritized
4. **Integration Coverage** - Component interaction paths
5. **Edge Case Coverage** - Boundary conditions tested
6. **Error Coverage** - Error handling paths verified
7. **Permission Coverage** - Access control scenarios
8. **AI Generation Quality** - AI-generated test effectiveness
## Coverage Targets | 覆蓋率目標
| Level | Coverage | Use Case | 適用場景 |
|-------|----------|----------|----------|
| Minimum | 60% | Legacy code | 遺留程式碼 |
| Standard | 80% | Most projects | 大多數專案 |
| High | 90% | Critical systems | 關鍵系統 |
| Critical | 95%+ | Safety-critical | 安全關鍵 |
## Workflow | 工作流程
1. **Run coverage tool** - Generate coverage report | 產生覆蓋率報告
2. **Analyze gaps** - Identify untested areas | 識別未測試區域
3. **Prioritize** - Rank by risk and importance | 依風險排序
4. **Recommend tests** - Suggest specific tests to add | 建議新增測試
5. **Track progress** - Monitor coverage over time | 追蹤進度
## Usage | 使用方式
```
/coverage - Run full coverage analysis | 執行完整覆蓋率分析
/coverage src/auth - Analyze specific module | 分析特定模組
/coverage --recommend - Get test recommendations | 取得測試建議
```
## Next Steps Guidance | 下一步引導
After `/coverage` completes, the AI assistant should suggest:
> **覆蓋率分析完成。建議下一步 / Coverage analysis complete. Suggested next steps:**
> - 覆蓋率不足 → 執行 `/tdd` 補齊測試 — Coverage gaps → Run `/tdd` to add tests
> - 已達標 → 執行 `/checkin` 品質關卡 ⭐ **Recommended / 推薦** — Targets met → Run `/checkin` quality gates
> - 發現熱點 → 執行 `/refactor` 改善可測試性 — Hotspots found → Run `/refactor`
