(a)
(b) when MAXPRIMES = 4, array will out of bound
(c) n = 1
(d) node coverage:
TR = {1,2,3,4,5,6,7,8,9,10,11,12,13,14,15,16}
Test Paths: [1,2,3,4,5,6,7,8,5,9,10,11,12,2,13,14,15,16]
edge coverage:
TR = {(1,2),(2,3),(3,4),(4,5),(5,6),(6,7),(6,8),(7,8),(8,5),(5,9),(9,10),(10,11),(11,12),(10,12),(12,2),(2,13),(13,14),(14,15),(15,14),(14,16)}
prime path coverage:
TR = {[1,2,13,14,16],[1,2,13,14,15],[1,2,3,4,5,6,7,8],[1,2,3,4,5,6,8],[1,2,3,4,5,9,10,11,12],[1,2,3,4,5,9,10,12]}
全路径覆盖的例子：
判断三角形是等边，等腰，还是普通三角形。
判断三角形代码：
public class triangle {
private static int result = -1;
public void triangle(int a,int b,int c)
{
if(a<=0 || b<=0 || c<=0)
{
result = -1;
}
else
{
if(((a+b)>c) && ((a+c)>b && (b+c)>a))
{
if((a == b) &&(a == c))
{
result = 3;
}
if((a==b && a!=c)||(a==c && a!=b)||(b==c && a!=b))
{
result = 2;
}
if(a!=b && a!=c && b!=c)
{
result = 1;
}
}
else
{
result = -1;
}
}
}
public int getResult(){
return result;
}
public void clear(){
result = -1;
}
}
测试代码：
import static org.junit.Assert.*;
import org.junit.Test;
public class test {
private static triangle cal = new triangle();
@Test
public void testTriangle(){
cal.triangle(3, 4, 5);
assertEquals(1, cal.getResult());
cal.triangle(3, 3, 5);
assertEquals(2, cal.getResult());
cal.triangle(6, 6, 6);
assertEquals(3, cal.getResult());
cal.triangle(10, 4, 4);
assertEquals(-1, cal.getResult());
cal.triangle(-1, 3, 4);
assertEquals(-1, cal.getResult());
}
}
这是代码的结构：
