5.1-测试与封装

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);
}
}
