1. Install Junit(4.12), Hamcrest(1.3) with Eclipse

下载junit,hamcrest

在工程下面新建文件lib，将junit,hamcrest copy到文件夹中，然后右键点击Build Path-Add Extend Archives

2. Install Eclemma with Eclipse

将eclemma压缩包下载下来后解压到Eclipse本地目录的dropins下，重启Eclipse即可：

重启后，eclipse上面出现如下标志，则插件安装成功

3.  Write a java program for the triangle problem and test the program with Junit.

a) Description of triangle problem:

Function triangle takes three integers a,b,c which are length of triangle sides; calculates whether the triangle is equilateral, isosceles, or scalene.

triangle.java

package cn.tju.scs;

public class triangle {
    public triangle(){}
    public String triangles(int a, int b, int c) {
        if(a + b > c && a + c > b && b + c > a)    
        {
            if(a == b && b == c)
                return "equilateral";
            else if(a == b || b == c || a == c)
                return "isosceles";
            else {
                return "scalene";
            }
        }
        else {
            return "Non-triangular";
        }
    }

}

testtriangle.java

package cn.tju.scs;

import static org.junit.Assert.*;
import static org.hamcrest.Matchers.*;
import org.junit.Before;
import org.junit.Test;

public class testtriangle {
    public triangle tr = new triangle();
    @Before
    public void setUp() throws Exception {
    }

    @Test
    public void testTrangle() {
        assertEquals("equilateral", tr.triangles(3, 3, 3));
        assertEquals("isosceles", tr.triangles(3, 2, 2));
        assertEquals("scalene", tr.triangles(3, 4, 2));
        assertEquals("Non-triangular", tr.triangles(2, 2, 4));
    }


}

结果如下：
