练习一下junit的用法，简单的引入junit jar包，然后导入就ok
package dxm.com.test;
import org.junit.Test;
public class TestJUnit {
@Test
public void Unites(){
System.out.println("c--------------");
}
@Test
public void A(){
System.out.println("a-----------------");
}
@Test(expected=ClassNotFoundException.class,timeout=1)
public void B(){
System.out.println("b-----------------");
}
}
