Tasks:

1. Install Junit(4.12), Hamcrest(1.3) with Eclipse
2. Install Eclemma with Eclipse
3. Write a java program for the triangle problem and test the program with Junit.

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.

junit,hamcrest,eclemma安装描述

JUnit,Harmcrest在新建工程的时候导入或着直接在工程中导入，Harmcrest的jar包链接
在项目中找到Build Path。将jar包路径添加到classpath中。
Eclemma可以通过eclipse的market安装，搜索Eclemma，同意安装后重启。

软件结构如下：

triangle代码如下：

package ST;

public class triangle {

	public String triangle (int a, int b,int c)
	{
		String str;
		int d=a-b;
		int e=b-c;
		int f=a-c;
	    if( d*e*f==0){
			str="isoscele";
		    if( (a==b) && (b==c) )
		    	str="equilateral";
		}
		else
			str="scalene";
		return str;
		
	}

}

triangleTS代码如下：

package ST;

 

import org.junit.Test;
import org.junit.runners.Parameterized.Parameters;
import static org.junit.Assert.*;
import static org.junit.Assert.assertEquals;
import java.util.Arrays;
import java.util.Collection;
import org.junit.Test;
import org.junit.runner.RunWith;
import org.junit.runners.Parameterized;
import ST.triangle;

import static org.junit.Assert.*;




@RunWith(Parameterized.class)
public class triangleTS {
	private String type;
	private int a;
	private int b;
	private int c;
	
	public triangleTS(String type, int a, int b, int c){
		this.type = type;
		this.a = a;
		this.b = b;
		this.c = c;
	}
	@Parameters
	public static Collection prepareData(){
		Object[][] object = {
				{"isoscele",1,1,1},
				{"equilateral",2,2,3},
				{"equilateral",2,3,3},
				{"scalene",2,3,4}};
		return Arrays.asList(object);
	}
	@Test
	public void TestTypeOfTriangle() 
	{
		triangle calc = new triangle (); 
		assertEquals (type, calc.triangle(a,b,c)); 
	}

}

测试结果

四组样例全部通过，且代码全被覆盖
