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);

               }

                     }
