1.介绍一下junit
   junit是一个用来单元测试的工具,它可以针对一�?多个�cȝ��单个或多个方法进行测�?�q�可以自动化套�g��试.��?a target="_blank">junit.jar包从www.junit.org.载下来放到eclipse ��目中的java build path�?
2.创徏一个TestCase
   File > New > JUnit Test Case 或者点�?strong>""来创��Z��个TestCase

   代码如下
   import junit.framework.TestCase;
   public class SampleTest extends TestCase {
     private java.util.List emptyList;
     /**
      * Sets up the test fixture.
      * (Called before every test case method.)
      */
     protected void setUp() {
          emptyList = new java.util.ArrayList();
     }
     /**
      * Tears down the test fixture.
      * (Called after every test case method.)
      */
     protected void tearDown() {
          emptyList = null;
     }
     public void testSomeBehavior() {
          assertEquals("Empty list should have 0 elements", 0, emptyList.size());
     }
     public void testForException() {
          try {
               Object o = emptyList.get(0);
               fail("Should raise an IndexOutOfBoundsException");
          }
          catch (IndexOutOfBoundsException success) {
          }
     }
}
�q�个例子有两个方法需要测�?�W�一个方法测试list中没有�Q何对�?�W�二个方法测试没有��用断�a�,它一定会成功

3.创徏一个TestSuite
   通过��试套�g可以�q�行多个��试用例
   (3.1)选择   File > New > Other... > Java > JUnit > JUnit Test Suite. 或�?img height="22" alt="newTestCase.gif" src="http://www.aygfsteel.com/images/blogjava_net/xzc520/newTestCase.gif" width="36" border="0" />Other... > Java > JUnit > JUnit Test Suite,
import junit.framework.Test;
import junit.framework.TestSuite;

public class AllTests {

    public static Test suite() {
        TestSuite suite = new TestSuite("Test for com.xu.Test");
        //$JUnit-BEGIN$
        suite.addTestSuite(SampleTest .class);
        //$JUnit-END$
        return suite;
    }

}
