    5.1 实验五 四则运算单元测试

    一、过程简介：

    工作人员：邵家文       学号：201306114322

                  李泳江       学号：201306114314          博客：http://www.cnblogs.com/mch-29-wamc/

     分工：邵家文：将代码封装成类，用数据做测试

             李泳江：记录数据，分析错误的原因。

    实验环境：Eclipse集成开发环境+JUnit4测试框架+java

    总结：这次跟泳江合作我感到很开心，泳江这次也帮了不少忙，解决了不少问题！

    二：代码简介(封装后的)

    4.修改后

    四：黑盒测试

    1.算法流程图与界面。

     

    2.根据以上流程图，与界面，覆盖用户操作的按钮，改变背景色的除外

     

    T1代表文本框

    B1代表"确定"

    B2代表"换题"

    T2代表文本框

    B3代表确定

    文本与按钮

    T1
