使用spring模拟rails的fixture来构建测试数据

 

 首先定义模型, User和Article为一对多的双向关联。

 

@Entity
public class User {
	@Id
	@GeneratedValue
	private int id;
	private String name;
	@OneToMany(mappedBy = "user", cascade = CascadeType.ALL)

 

@Entity
public class Article {
	@Id
	@GeneratedValue
	private int id;
	private String title;
	@ManyToOne
	private User user;

 

然后将fixture定义在spring的context中,如下:

 

<bean id="me" class="com.springfixture.domain.User">
	<property name="name" value="admin"/>
	<property name="articles">
	   	<set>
			<ref bean="article"/>
			 <ref bean="aboutTest"/>
		</set>
	</property>
</bean>
<bean id="article" class="com.springfixture.domain.Article">
	<property name="title" value="spring fixtures guide"/>
	<property name="user" ref="me"/>
</bean>
<bean id="aboutTest" parent="article">
	<property name="title" value="How to test"></property>
</bean>

 然后在测试类中:

 

//加载数据
@Before
public void loadData(){
	new SpringFixture(this.sessionFactory).loadData(this);
}

//注入单个测试对象, “me”为bean的名称
@Fixture("me")
private User user;

//也可以直接作为变量名
@Fixture
private User me;

//注入多个对象
@Fixture(type=Article.class)
private List<Article> articles;

 

最后请看看源代码,有什么好的建议一起研究研究,谢谢!
