1.在eclipse新建一个java project

2.新建一个class: hello, package = example, 代码如下：

package  example;

public   class  hello
{
  public   int  abs( int  n)
 {
   return  n  >=   0   ?  n : ( - n);
 }
}

3.右键点击hello.java，选择：new - junit test case
setUp / tearDown打钩, 最下方click here点击，添加JUnit.jar文件 - next

4.选择abs()方法

5.修改Hellotest代码：

package  example;

import  junit.framework.TestCase;

public   class  helloTest  extends  TestCase
{
     private  hello _hello;

     protected   void  setUp()  throws  Exception
    {
         super .setUp();

        _hello  =   new  hello();
    }

     protected   void  tearDown()  throws  Exception
    {
         super .tearDown();
    }

     public   void  testAbs()
    {
        assertEquals(_hello.abs( 14 ),  14 );
        assertEquals(_hello.abs( - 5 ),  5 );
        assertEquals(_hello.abs( 0 ),  0 );
    }
}

6. 运行
