软件测试 实验一

一、junit、hamcrest和eclemma的安装。

1.junit和hamcrest在新建了junitHw1工程后在build path里通过add external jars添加junit－4.12.jar和hamcrest－all－1.3.jar。

2.eclemma在eclipse下点击help－eclipse marketplace－find－eclemma安装。

二、编写Triangle以及TestTriangle1。

1.Triangle－判断三角形类型

public class Triangle {
	 int[] data; 
	 Triangle(){
		 data = new int[3];
	 }
	 public void setData(int[] number){
		 for(int i = 0;i < data.length;i++){
			 data[i] = number[i];
		 }
	 }
     public String checkTriangle(){
    	 for(int i = 0;i < data.length;i++){
    	  if(data[i]<=0)
    		  return "Illegal";
    	 }
    	 if(data[0]+data[1]<=data[2]||data[0]+data[2]<=data[1]||data[1]+data[2]<=data[0]){
    		 return "Not triangle";
    	 }
    	 else if(data[0]==data[1]&&data[0]==data[2]){
    		 return "Equilateral";
    	 }
    	 else if(data[0]==data[1]||data[0]==data[2]||data[1]==data[2]){
    		 return "Isosceles";
    	 }
    	 else
    		 return "Scalene";
     }
}

 2.TriangleTest

import static org.junit.Assert.*;

import java.util.Arrays;
import java.util.Collection;

import org.junit.Test;
import org.junit.runner.RunWith;
import org.junit.runners.Parameterized;
import org.junit.runners.Parameterized.Parameters;

@RunWith(Parameterized.class)
public class TriangleTest{
	
	@Parameters
	public static Collection prepareData(){
	return Arrays.asList(new Object[][]{{1,3,5,"Not triangle"},{1,2,-3,"Illegal"},{3,4,5,"Scalene"},
			{2,2,2,"Equilateral"},{2,3,3,"Isosceles"}});
	}
	public TriangleTest(int param1,int param2,int param3,String result){
	this.param1 = param1;
	this.param2 = param2;
	this.param3 = param3;
	this.result = result;
	}
	@Test
	public void Test(){
	triangle.setData(new int[]{param1,param2,param3});
	assertEquals(result, triangle.checkTriangle());
	}
	private int param1,param2,param3;
	private String result;
	private static Triangle triangle = new Triangle();
}

 三、测试结果
