Unitils is an interesting new open source project trying to make unit testing as easy and maintainable as possible. Together with their 1.0 RC1 release the Unitils team have published Testing Spring - Hibernate applications with Unitils which illustrates using Unitils in a typical Spring/Hibernate application. The way Unitils integrates with DbUnit and automagically does test database maintenance is particularly interesting.
如何测试Spring - Hibernate , 首先是一个HibernatePhonebook 的类，继承了HibernateDaoSupport 从数据库读取Person信息
public class HibernatePhonebook extends HibernateDaoSupport implements Phonebook {
public List<Person> searchByLastName(String lastName) {
return (List<Person>) getHibernateTemplate().executeFind(new HibernateCallback() {
public Object doInHibernate(Session session) throws HibernateException, SQLException {
Criteria personCriteria = session.createCriteria(Person.class);
personCriteria.setResultTransformer(Criteria.DISTINCT_ROOT_ENTITY);
personCriteria.add(Restrictions.like("lastName", criteria.getLastName(), MatchMode.ANYWHERE));
return personCriteria.list();
}
});
}
}
public class HibernatePhonebook extends HibernateDaoSupport implements Phonebook {
public List<Person> searchByLastName(String lastName) {
return (List<Person>) getHibernateTemplate().executeFind(new HibernateCallback() {
public Object doInHibernate(Session session) throws HibernateException, SQLException {
Criteria personCriteria = session.createCriteria(Person.class);
personCriteria.setResultTransformer(Criteria.DISTINCT_ROOT_ENTITY);
personCriteria.add(Restrictions.like("lastName", criteria.getLastName(), MatchMode.ANYWHERE));
return personCriteria.list();
}
});
}
} 它的测试也非常的简单，如下 view plaincopy to clipboardprint?
@ApplicationContext({"classpath:services-config.xml", "classpath:test-ds-config.xml"})
public class UnitilsHibernatePhonebookTest extends UnitilsJUnit3 {
@SpringBeanByType
private Phonebook phonebook;
@DataSet
public void testSearchByLastName() {
List<Person> result = phonebook.searchByLastName("Doe"));
ReflectionAssert.assertPropertyLenEquals("firstName", Arrays.asList("John", "Jane"), result);
}
}
@ApplicationContext({"classpath:services-config.xml", "classpath:test-ds-config.xml"})
public class UnitilsHibernatePhonebookTest extends UnitilsJUnit3 {
@SpringBeanByType
private Phonebook phonebook;
@DataSet
public void testSearchByLastName() {
List<Person> result = phonebook.searchByLastName("Doe"));
ReflectionAssert.assertPropertyLenEquals("firstName", Arrays.asList("John", "Jane"), result);
}
} 首先要继承UnitilsJUnit3 view plaincopy to clipboardprint?
public class UnitilsHibernatePhonebookTest extends UnitilsJUnit3 {
public class UnitilsHibernatePhonebookTest extends UnitilsJUnit3 { 还要写annotation来读取入相应的spring配置 view plaincopy to clipboardprint?
@ApplicationContext({"classpath:services-config.xml", "classpath:test-ds-config.xml"})
@ApplicationContext({"classpath:services-config.xml", "classpath:test-ds-config.xml"}) 通过Bean的属性来get bean,相信应该也有 ByName的方法 view plaincopy to clipboardprint?
@SpringBeanByType
private Phonebook phonebook;
@SpringBeanByType
private Phonebook phonebook; 以下是Spring的配置文件 view plaincopy to clipboardprint?
<?xml version="1.0" encoding="UTF-8"?>
<beans>
<bean id="phonebook" class="org.unitils.sample.phonebook.impl.HibernatePhoneBook">
<property name="sessionFactory" ref="sessionFactoryBean"/>
</bean>
<bean id="sessionFactoryBean" class="org.springframework.orm.hibernate3.annotation.AnnotationSessionFactoryBean">
<property name="dataSource" ref="dataSource"/>
<property name="annotatedClasses">

<property name="hibernateProperties">

<?xml version="1.0" encoding="UTF-8"?>

<bean id="phonebook" class="org.unitils.sample.phonebook.impl.HibernatePhoneBook">
<property name="sessionFactory" ref="sessionFactoryBean"/>

<bean id="sessionFactoryBean" class="org.springframework.orm.hibernate3.annotation.AnnotationSessionFactoryBean">

</property>
<property name="hibernateProperties">
<value>
hibernate.dialect=org.hibernate.dialect.HSQLDialect
hibernate.show_sql=true
</value>
</property>
</bean>
</beans> 这里的datasource 在测试时暂时改为UnitilsDataSource view plaincopy to clipboardprint?
<?xml version="1.0" encoding="UTF-8"?>
<beans>
<bean id="dataSource" class="org.unitils.database.UnitilsDataSource" />
</beans>
<?xml version="1.0" encoding="UTF-8"?>
<beans>
<bean id="dataSource" class="org.unitils.database.UnitilsDataSource" />
</beans> @DataSet annotation 让方法从 中获取出测试模拟数据 view plaincopy to clipboardprint?
@DataSet
public void testSearch() {
@DataSet
public void testSearch() { view plaincopy to clipboardprint?
<?xml version='1.0' encoding='UTF-8'?>
<dataset>
<PERSON FIRSTNAME="John" LASTNAME="Doe" />
<PERSON FIRSTNAME="Jane" LASTNAME="Doe" />
<PERSON FIRSTNAME="Jim" LASTNAME="Smith" />
</dataset>
<?xml version='1.0' encoding='UTF-8'?>
<dataset>
<PERSON FIRSTNAME="John" LASTNAME="Doe" />
<PERSON FIRSTNAME="Jane" LASTNAME="Doe" />
<PERSON FIRSTNAME="Jim" LASTNAME="Smith" />
</dataset> 用java reflection来比较实际获得的值和期望值 view plaincopy to clipboardprint?
ReflectionAssert.assertRefEquals(new Person("John", "Doe"), result.get(0));
ReflectionAssert.assertPropertyRefEquals("firstName", Arrays.asList("John", "Jane"), result);
ReflectionAssert.assertRefEquals(new Person("John", "Doe"), result.get(0));
ReflectionAssert.assertPropertyRefEquals("firstName", Arrays.asList("John", "Jane"), result); 还附带一些其他的比较方式 view plaincopy to clipboardprint?
ReflectionAssert.assertLenEquals(new Person("John", null), result.get(0));
ReflectionAssert.assertPropertyLenEquals("firstName", Arrays.asList("John", "Jane"), result);
