JUnit测试工具在项目中的用法

0:33 2013/6/26三大框架整合时为什么要对项目进行junit测试:
|__目的是测试配置文件对不对,能跑通就可以进行开发了具体测试步骤:
|__1.对hibernate进行测试 配置hibernate.cfg.xml
public class TestHibernate {
@Test
public void save(){
Configuration configuration = new Configuration();
//加载类路径下的hibernate.cfg.xml
configuration.configure();
SessionFactory sf = configuration.buildSessionFactory();
Session s = sf.openSession();
Transaction tr = s.beginTransaction();
//操作对象，就是操作表的过程
ElecText elecText = new ElecText();
elecText.setTextName("测试Hibernate名称");
elecText.setTextDate(new Date());
elecText.setTextRemark("测试Hibernate备注");
s.save(elecText);
tr.commit();
s.close();
}
}
|__2.对dao进行测试 测试之前确保beans.xml文件已配置,数据源可以暂时先不引不用开Tomcat不需要jsp进行显示
public class TestDao {
/**保存*/
@Test
public void save(){
ApplicationContext ac = new ClassPathXmlApplicationContext("beans.xml");
IElecTextDao elecTextDao = (IElecTextDao) ac.getBean(IElecTextDao.SERVICE_NAME);
ElecText elecText = new ElecText();
elecText.setTextName("测试Dao名称");
elecText.setTextDate(new Date());
elecText.setTextRemark("测试DAO备注");
elecTextDao.save(elecText);
}
}
|__3.对service进行测试 测试之前确保beans.xml文件已配置,数据源可以暂时先不引不要开Tomcat不需要jsp进行显示
public class TestService {
@Test
public void saveElecText(){
ApplicationContext ac = new ClassPathXmlApplicationContext("beans.xml");
IElecTextService elecTextService = (IElecTextService) ac.getBean(IElecTextService.SERVICE_NAME);
ElecText elecText = new ElecText();
elecText.setTextName("测试Service名称");
elecText.setTextDate(new Date());
elecText.setTextRemark("测试Service备注");
elecTextService.saveElecText(elecText);
}
}
|__4.对二级缓存进行测试 配置hibernate.cfg.xml
public class TestHibernateCache {
/**测试类级别的缓存*/
@Test
public void classCache(){
Configuration configuration = new Configuration();
//加载类路径下的hibernate.cfg.xml
configuration.configure();
SessionFactory sf = configuration.buildSessionFactory();
/***************************************************************/ Session s = sf.openSession();
Transaction tr = s.beginTransaction(); ElecSystemDDL e1 = (ElecSystemDDL) s.get(ElecSystemDDL.class, 1);//产生select语句
ElecSystemDDL e2 = (ElecSystemDDL) s.get(ElecSystemDDL.class, 1);//不产生select语句,从一级缓存中读取 tr.commit();
s.close();//一级缓存关闭了 /********************************************************************/
s = sf.openSession();
tr = s.beginTransaction(); ElecSystemDDL e3 = (ElecSystemDDL) s.get(ElecSystemDDL.class, 1);//不产生select语句,从二级缓存中读取 tr.commit();
s.close();
}
}
|__5.对jbpm进行测试 测试之前确保beans.xml文件已配置,数据源可以暂时先不引不要开Tomcat不需要jsp进行显示
public class TestJbpm {
/**生成JBPM的18张表*/
@Test
public void createTable_18(){
ApplicationContext ac = new ClassPathXmlApplicationContext("beans.xml");
SessionFactory sf = (SessionFactory) ac.getBean("sessionFactory");
System.out.println("sf:"+sf);
} /**测试流程引擎对象*/
@Test
public void testProcessEngine(){
ApplicationContext ac = new ClassPathXmlApplicationContext("beans.xml");
ProcessEngine processEngine = (ProcessEngine) ac.getBean("processEngine");
System.out.println("processEngine:"+processEngine);
}
}
