实验报告
a) The brief description that I install junit, hamcrest and eclemma.
Junit，hamcrest
上网下载junit,hamrest包，然后在项目中新建文件夹lib,复制包到其中，然后单击项目->build path -> configer build path,然后在把包加入，如图
Eclemma
解压 eclemma压缩包，将其复制于eclipse->dropins文件夹下。删除META-INF文件夹。
b） The test result and coverage report (print screen) of your tests on triangle problem.
代码：
package homeWork1;
public class Triangle {
public boolean lengthTest(int a , int b, int c){
if ( a + b > c && a + c > b && b + c > a){
return true;
}else{
return false;
}
}
public boolean isPositive(int a , int b , int c){
boolean ans = true;
if (a <= 0 || b <= 0 || c <=0 ){
ans = false;
//System.out.println("The number of edge must be a positive number");
}
return ans;
}
public boolean isTriangle(int a, int b , int c){
if(isPositive(a,b,c)){
if(lengthTest(a,b,c)){
return true;
}else{
//System.out.println("It can't be a triangle.");
return false;
}
}else{
return false;
}
}
public String function(int a, int b, int c){
if(isTriangle(a,b,c)){
if (a == b && b == c){
return "equilateral";
}else if(a == b || b == c || a == c){
return "isosceles";
}else{
return "scalene";
}
}else{
return "noTriangle";
}
}
}
测试代码;
package homeWork1;
import static org.junit.Assert.assertEquals;
import org.junit.After;
import org.junit.Before;
import org.junit.Test;
public class TriangleTest {
Triangle t1 = new Triangle();
public void test(){
assertEquals("noTriangle",t1.function(-1, 2, 3));
assertEquals("noTriangle",t1.function(1, 2, 3));
assertEquals("noTriangle",t1.function(8, 2, 3));
assertEquals("equilateral",t1.function(3, 3, 3));
assertEquals("isosceles",t1.function(3, 3, 2));
assertEquals("scalene",t1.function(3, 4, 2));
}
public static void main(String[] args) {
TriangleTest t2 = new TriangleTest();
t2.test();
}
}
覆盖结果：
