孩子,你還得練,還得練! 記錄生活點點滴滴 讓程式更精彩

Cobertura是一個基於jcoverage的免費Java工具,它能夠顯示哪一部分程式碼被你的測試所覆蓋,並可生成HTML或XML 報告.
cobertura 的大概基本工作思路:
1.對已經編譯好的class 檔案新增標記
2. 對新增好標記的程式碼進行單元測試
3. 輸出覆蓋率統計報告
在ant 中使用cobertura 的基本步驟:
1. 編譯程式碼
2. 定義cobertura 的ant task
3. 用nstrument 命令為編譯好的程式碼新增標記
4. 用junit 命令對新增好標記的程式碼進行單元測試
5. 用cobertura-report 命令輸出報告
