我们先看一下在JUnit 3中我们是怎样写一个单元测试的。比如下面一个类：

public class AddOperation {
      public int add(int x,int y){
          return x+y;
      }
}

我们要测试add这个方法，我们写单元测试得这么写：

import junit.framework.TestCase;
import static org.junit.Assert.*;
public class AddOperationTest extends TestCase{

      public void setUp() throws Exception {
      }

      public void tearDown() throws Exception {
      }

      public void testAdd() {
          System.out.println(\"add\");
          int x = 0;
          int y = 0;
          AddOperation instance = new AddOperation();
          int expResult = 0;
          int result = instance.add(x, y);
          assertEquals(expResult, result);
      }
}

import junit.framework.TestCase;
import org.junit.After;
import org.junit.Before;
import org.junit.Test;
import static org.junit.Assert.*;

public class AddOperationTest extends TestCase{
   
      public AddOperationTest() {
      }

      @Before
      public void setUp() throws Exception {
      }

      @After
      public void tearDown() throws Exception {
      }

      @Test
      public void add() {
          System.out.println(\"add\");
          int x = 0;
          int y = 0;
          AddOperation instance = new AddOperation();
          int expResult = 0;
          int result = instance.add(x, y);
          assertEquals(expResult, result);
      }
   
}
