1.开发环境---Eclipse，Eclipse-Junit4
2.人员---吕日荣（201306114315）、张梓锋（201306114318）
第一阶段---把计算核心算法封装成类
package sizeyunsuan; public class SiZeYunSuan { int ranswer=0; public int test1(char op,int a,int b){ switch(op) { case '+': ranswer=a+b;break; case '-': ranswer=a-b;break; case '*': ranswer=a*b;break; case '/': ranswer=a/b;break; } return ranswer; } public int test2(int c){ int jc=1; for(int i=c;i>0;i--) { jc=jc*i; } ranswer=jc; return ranswer; } }
第二阶段---对这个测试类进行单元测试
package sizeyunsuan; import static org.junit.Assert.*; import org.junit.Test; public class SiZeYunSuanTest { @Test public void testTest1() { SiZeYunSuan core=new SiZeYunSuan(); int a=core.test1('-',2,8); assertEquals(-6,a); } @Test public void testTest2() { SiZeYunSuan core=new SiZeYunSuan(); int a=core.test1('+',3,6); assertEquals(9,a); } @Test public void testTest3() { SiZeYunSuan core=new SiZeYunSuan(); int a=core.test1('*',2,9); assertEquals(18,a); } @Test public void testTest4() { SiZeYunSuan core=new SiZeYunSuan(); int a=core.test1('/',6,3); assertEquals(2,a); } @Test public void testTest5() { SiZeYunSuan core=new SiZeYunSuan(); int b=core.test2(3); assertEquals(6,b); } @Test public void testTest6() { SiZeYunSuan core=new SiZeYunSuan(); int b=core.test2(4); assertEquals(24,b); } }
第三阶段---白盒测试
| 编号 | 输入数据 | 预期输出数据（a或b的值） | 实际输出数据（a或b的值） | 正确与否 |
| 1 | （‘-’，2,8） |
-6 |
-6 | 正确 |
| 2 | （‘+’，3,6） | 9 | 9 | 正确 |
| 3 | （‘*’，2,9） | 18 | 18 | 正确 |
| 4 | （‘/’，6,3） | 2 | 2 | 正确 |
| 5 | （3） | 6 | 6 | 正确 |
| 6 | （4） | 24 | 24 | 正确 |
| 7 | （5） | 120 | 121 | 错误 |
第四阶段---黑盒测试
