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。

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

• Code Coverage - Lines, branches, functions

• Requirement Coverage - All requirements have tests

• Risk Coverage - High-risk areas prioritized

• Integration Coverage - Component interaction paths

• Edge Case Coverage - Boundary conditions tested

• Error Coverage - Error handling paths verified

• Permission Coverage - Access control scenarios

• 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

• Run coverage tool - Generate coverage report | 產生覆蓋率報告

• Analyze gaps - Identify untested areas | 識別未測試區域

• Prioritize - Rank by risk and importance | 依風險排序

• Recommend tests - Suggest specific tests to add | 建議新增測試

• 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 — Targets met → Run /checkin quality gates

• 發現熱點 → 執行 /refactor 改善可測試性 — Hotspots found → Run /refactor
