import static org.junit.Assert.*;

import org.junit.After;
import org.junit.AfterClass;
import org.junit.Before;
import org.junit.BeforeClass;
import org.junit.Test;

public class TriangleTest {

    @BeforeClass
    public static void setUpBeforeClass() throws Exception {
    }

    @AfterClass
    public static void tearDownAfterClass() throws Exception {
    }

    @Before

    }

    @After
    public void tearDown() throws Exception {
    }

    @Test
    public void testCheck() {

           assertEquals( Triangle.check(1,1,1) , 1 );


           assertEquals( Triangle.check(2,2,3) , 2 );


           assertEquals( Triangle.check(2,3,4) , 3 );


           assertEquals( Triangle.check(1,1,3) , -1 );
    }

}

 

二．实验过程

1．JUnit、Hamcrest的安装：

1)从网上下载junit-4.12.jar 和 hamcrest-all-1.3.jar文件。

 

2)在Eclipse中新建项目 （File - new - javaproject）

右键点击项目，选择Build Path - Configure Build Path

然后点击Libraries - Add External JARs，选择jar包打开，确认

 

2.Eclemma的安装：

在菜单栏选择Help - Eclipse Marketplace，搜索Eclemma，点击Install安装，重启Eclipse

 

 Triangle Problem

import java.util.Scanner;

public class  Triangle {

public static final int equilateral= 1;
public static final int isosceles= 2;
public static final int scalene= 3;


    public static int check(int a,int b,int c){


       if(a+b>c&&a+c>b&&b+c>a){

           if(a==b&&b==c) return equilateral;  //equilateral

           else if(a==b||b==c||a==c) return isosceles;  //isosceles

           else return scalene;  //scalene

       }

       else return -1;

    }

 

}

Junit test

import static org.junit.Assert.*;

import org.junit.After;
import org.junit.AfterClass;
import org.junit.Before;
import org.junit.BeforeClass;
import org.junit.Test;

public class TriangleTest {

    @BeforeClass
    public static void setUpBeforeClass() throws Exception {
    }

    @AfterClass
    public static void tearDownAfterClass() throws Exception {
    }

    @Before
    public void setUp() throws Exception {
    }

    @After
    public void tearDown() throws Exception {
    }

    @Test
    public void testCheck() {

           assertEquals( Triangle.check(1,1,1) , 1 );


           assertEquals( Triangle.check(2,2,3) , 2 );


           assertEquals( Triangle.check(2,3,4) , 3 );


           assertEquals( Triangle.check(1,1,3) , -1 );
    }

}
