繼續 簡介 Cobertura 的說明,直接下 Cobertura 指令太過麻煩,可以使用Ant設定好相關資訊後,後續就交給Ant來處理,相關設定可以參考Cobertura官網的 Ant Task Reference。
例如,在簡介 Cobertura 的範例專案結構下,以下是個參考的範本,重要設定的部份以粗體表示:
<?xml version="1.0" encoding="UTF-8"?>

至於Maven 的結合,可以參考 http://cobertura.sourceforge.net/maven.html 的內容,最簡單的情況下,要產生測試覆蓋率報告,只要下 cobertura:cobertura。
