package com.jmesa.test.dao; import java.util.List; import com.jmesa.test.common.EntityFilters; import com.jmesa.test.common.EntitySorts; import com.jmesa.test.model.Boy; public interface BoysDAO { /** * * @param boy * 域对象 */ public void save(Boy boy); /** * 更新boy数据 * * @param boy */ public void update(Boy boy); /** * 依据id值获得boy域对象 * * @param id * @return */ public Boy get(String id); /** * 获得所有boy域对象 * * @return */ public List<Boy> getAll(); /** * 依据boy 属性条件查询boy列表 * * @param phone * 空或者null值将不作为查询条件 * @param sex * 空或者null值将不作为查询条件 * @return */ public List<Boy> queryBoys(String phone, String sex); }
开始测试:
package com.jmesa.test.dao.hibernate; import java.sql.SQLException; import java.util.List; import org.hibernate.Criteria; import org.hibernate.HibernateException; import org.hibernate.Session; import org.hibernate.criterion.DetachedCriteria; import org.hibernate.criterion.Projections; import org.hibernate.criterion.Property; import org.springframework.orm.hibernate3.HibernateCallback; import org.springframework.orm.hibernate3.support.HibernateDaoSupport; import com.jmesa.test.dao.BoysDAO; import com.jmesa.test.model.Boy; public class BoysDAOImpl extends HibernateDaoSupport implements BoysDAO { public Boy get(String id) { return (Boy) this.getHibernateTemplate().load(Boy.class, id); } public List<Boy> getAll() { return queryBoys(null, null); } public List<Boy> queryBoys(String phone, String sex) { DetachedCriteria query = DetachedCriteria.forClass(Boy.class); if (phone != null && !phone.equals("")) { query.add(Property.forName("phone").eq(phone)); } if (sex != null && !sex.equals("")) { query.add(Property.forName("sex").eq(sex)); } return this.getHibernateTemplate().findByCriteria(query); } public void save(Boy boy) { this.getHibernateTemplate().save(boy); } public void update(Boy boy) { this.getHibernateTemplate().update(boy); } }
package com.jmesa.test.integrateTest; import org.springframework.test.AbstractTransactionalDataSourceSpringContextTests; public class BaseDataSourceSpringContextIntegrationTest extends AbstractTransactionalDataSourceSpringContextTests { //加载spring配置文件,其路径在classpath的根目录下 private static final String[] configFiles = new String[] { "applicationContext-resources.xml", "applicationContext-dao.xml" }; //设置dao类的注入方式,默认为类型注入,此处改为名称注入 public BaseDataSourceSpringContextIntegrationTest() { this.setAutowireMode(AUTOWIRE_BY_NAME); } //通过此方法提供spring配置文件 protected String[] getConfigLocations() { return configFiles; } }
BoysDAO的测试类:
package com.jmesa.test.integrateTest; import java.util.List; import org.junit.Assert; import org.junit.Test; import com.jmesa.test.common.EntityFilters; import com.jmesa.test.common.EntitySorts; import com.jmesa.test.dao.BoysDAO; import com.jmesa.test.model.Boy; /** * @author jack */ public class BoyDAOTest extends BaseDataSourceSpringContextIntegrationTest { private BoysDAO boysDAO; public BoyDAOTest(){ } /** * 必须要提供变量boysDAO的setter方法,这样注入才会成功 */ public void setBoysDAO(BoysDAO boysDAO) { this.boysDAO = boysDAO; } @before public void initialize(){ } @after public void destroy(){ } @Test public void testGetAll(){ int count = this.countRowsInTable("boys"); Assert.assertEquals(boysDAO.getAll().size(),count); } @Test public void testQueryBoys(){ Assert.assertEquals(0,boysDAO.queryBoys("www", "wwww").size()); Assert.assertEquals(1,boysDAO.queryBoys("eee", "33").size()); } @Test public void testSave(){ int boysCount = this.countRowsInTable("boys"); String phone ="13401108995"; String sex = "1"; String address = "南京路"; Boy boy = new Boy(); boy.setPhone(phone); boy.setSex(sex); boy.setAddress(address); boysDAO.save(boy); Assert.assertEquals(boysCount+1, this.countRowsInTable("boys")); } @Test public void testGetBoysCountWithFilter(){ EntityFilters entityFilters = new EntityFilters(); int count = boysDAO.getBoysCountWithFilter(entityFilters); Assert.assertEquals(20, count); EntityFilters entityFilters1 = new EntityFilters(); entityFilters1.addFilter("phone", "342432"); int size = entityFilters1.filterSize(); int count1 = boysDAO.getBoysCountWithFilter(entityFilters1); Assert.assertEquals(1, count1); } @Test public void testGetBoysWithFilterAndSort(){ EntityFilters entityFilters = new EntityFilters(); //entityFilters.addFilter("phone", "342432"); EntitySorts entitySorts = new EntitySorts(); entitySorts.addSort("phone", "desc"); List<Boy> boysList = boysDAO.getBoysWithFilterAndSort(entityFilters, entitySorts, 0, 10); Assert.assertEquals(10, boysList.size()); Boy boy = boysList.get(0); Assert.assertEquals("ww",boy.getPhone() ); } }
此处测试用到了 AbstractTransactionalDataSourceSpringContextTests 的四方面的功能:
1. 加载spring的资源配置文件
2. dao bean 引入测试类
3. 简便的函数使用,如:countRowsInTable
4. 事务自动回滚.
请注意此BoyDAOTest测试类中使用@before,@after修饰的方法在测试中没有被执行, 可能原因是BoyDAOTest 间接继承了TestCase类,要想执行此类方法,必须沿用以前版本的junit的setUp,tearDown
方法,然而AbstractTransactionalDataSourceSpringContextTests 类已经overide此方法,并且加了final修饰,其子类不可以在overide了. 所以加入类似before,after这样的方法,目前还没有想出比较好的办法? 还请大侠们赐教.
