用这个框架：
import junit.framework.*;
import org.junit.After;
import org.junit.AfterClass;
import org.junit.Before;
import org.junit.BeforeClass;
import org.junit.Test;
import static org.junit.Assert.*;
public class NewEmptyJUnitTest {
public NewEmptyJUnitTest() {
}
@BeforeClass
public static void setUpClass() throws Exception {
}
@AfterClass
public static void tearDownClass() throws Exception {
}
@Before
public void setUp() {
//进行测试前要跑的代码放这里
}
@After
public void tearDown() {
//进行测试后要跑的代码放这里
}
// The methods must be annotated with annotation @Test. For example:
//
// @Test
// public void hello() {}
}
在测试方法前加上@Test，在里头用断言方法进行测试。
另：
Junit java doc:
http://junit.org/junit/javadoc/4.5/
具体的断言方法都放在 junit.framework.Assert这个类里头，你可以参考一下。
用junit测试最好带上集成开发工具，因为集成开发工具里的测试运行都是自动的，你只要专注于你要跑的测试代码就行了。
常用的Java集成开发工具(都是免费的)：
NetBeans下载地址：NetBeans.org (我用的就是这个，有中文版)
eclipse下载地址：eclipse.org （3.4以下有中文版)
