1.第一阶段目标 - 把计算的功能封装成类。
1 package GongNengpk; 2 3 public class HeXinCode { 4 5 int temp=0; 6 int answer=0; 7 public int JJCC(char op,int a,int b) 8 { 9 switch(op) 10 { 11 case '+': answer=a+b; break; 12 case '-': answer=a-b; break; 13 case '*': answer=a*b; break; 14 case '/': answer=a/b; break; 15 } 16 return answer; 17 } 18 public int JC(int c) 19 { 20 int jc=1; 21 for(int i=c;i>0;i--) 22 { 23 jc=jc*i; 24 } 25 answer=jc; 26 return answer; 27 } 28 29 }
简单的把加减乘除和阶乘算法封装成一个Class。
2.设计测试用例：用白盒与黑盒测试设计技术，为计算核心设计测试用例。
白盒测试:
黑盒测试：
3.在实验环境中（如MyEclipse集成开发环境+Junit测试框架）运行测试用例，分析测试结果，找出程序问题，给出改进前后的代码对照。
Junit测试
测试源代码：
1 package GongNengpkTest; 2 3 import static org.junit.Assert.*; 4 5 import org.junit.Test; 6 7 import GongNengpk.HeXinCode; 8 9 public class HeXinCodeTest { 10 11 @Test 12 public void testJJCC() { 13 HeXinCode hx=new HeXinCode(); 14 int num_1=hx.JJCC('+', 3, 6); 15 assertEquals(9,num_1); 16 int num_2=hx.JJCC('-', 3, 6); 17 assertEquals(-3,num_2); 18 int num_3=hx.JJCC('*', 3, 6); 19 assertEquals(18,num_3); 20 int num_4=hx.JJCC('/', 6, 3); 21 assertEquals(2,num_4); 22 23 } 24 25 @Test 26 public void testJC() { 27 HeXinCode hx=new HeXinCode(); 28 int num_5=hx.JC(3); 29 assertEquals(6,num_5); 30 } 31 32 }

总结：
本次作业按老师的要求换了队友（http://www.cnblogs.com/yuhancheng/）。这次作业真的是一个很大的挑战。挑战了之前一直没有做过了的东西。一开始，老师叫我做这个封装、黑盒、白盒测试我是拒绝的，因为不能叫我做我就做嘛，但是我真的不会做啊~~~上课时老师说这些内容是真的是听不懂，更不要说做了。可是通过向老师提问和学习网上的教程，然后就渐渐地明白了。我的理解是，白盒测试可以让我们更清晰这个程序的思维，黑盒测试是为了帮助我们发现程序中的bug，让我们加以改善。其实还是不够了解，哈哈。只能通过更多的方法去加深对单元测试的理解。
