本文详细介绍如何在Eclipse环境下配置JUnit4进行单元测试。包括环境搭建步骤、项目结构展示、具体代码示例及Ant构建脚本说明。

环境：win7+eclipse+jdk1.7+junit4

1.环境配置

项目下新建lib文件夹

将juint4.12 复制进lib目录下

右键--build path--config build path--libraries--add jars--junit-4.12.jar

2.项目结构

项目
    --src
        --package
            --class
        --testpackage
            --testclass
    --lib
        --junit4.12.jar
    --build.xml

3.代码

Sample.java

package testjunitsample;

public class Sample {

 public int add(int x,int y){
  return x+y;
 }
 
 public int sub(int x,int y){
  return x-y;
 }
}

TestSample.java

package testjunitsample;

import junit.framework.TestCase;
import org.junit.Assert;
import org.junit.Before;
import org.junit.Test;

public class TestSample extends TestCase {
 
 private Sample sp ;
 @Before
 public void setUp() throws Exception {
  sp = new Sample();
  System.out.println("init.....");
 }

 @Test
 public void testAdd(){
  int y = sp.add(1, 2);
  Assert.assertEquals(3, y);
 }
 
 @Test
 public void testSub(){
  int z= sp.sub(4, 2);
  Assert.assertEquals(2, z);
 }
}

build.xml

</project>
