收集整理的這篇文章主要介紹了
5.1 实验五 四则运算单元测试
小編覺得挺不錯的,現在分享給大家,幫大家做個參考.
5.1 實驗五 四則運算單元測試
一、過程簡介：
工作人員：邵家文 ? ? ? 學號：201306114322
? ? ? ? ? ? ? 李泳江 ? ? ? 學號：201306114314 ? ? ? ? ?博客：http://www.cnblogs.com/mch-29-wamc/
?分工：邵家文：將代碼封裝成類，用數據做測試
? ? ? ? ?李泳江：記錄數據，分析錯誤的原因。
實驗環境：Eclipse集成開發環境+JUnit4測試框架+java
總結：這次跟泳江合作我感到很開心，泳江這次也幫了不少忙，解決了不少問題！
