spring3.0 单元测试

spring3.0.0之后的版本，官方极力推荐使用如下方式做单元测试。

 

跟junit的单测方式没有大的区别，但是对配置文件的加载，bean的注入灵活了许多。根据官方手册，简单记录下。

 

1. 配置文件加载

    方式一：

 

@RunWith(SpringJUnit4ClassRunner.class)
// ApplicationContext will be loaded from "/applicationContext.xml" and "/applicationContext-test.xml"
// in the root of the classpath
@ContextConfiguration({"/applicationContext.xml", "/applicationContext-test.xml"})
public class MyTest {
   // class body...
}

    方式二：

 

@RunWith(SpringJUnit4ClassRunner.class)
// ApplicationContext will be loaded from "/base-context.xml" in the root of the classpath
@ContextConfiguration("/base-context.xml")
public class BaseTest {
   // class body...
}
// ApplicationContext will be loaded from "/base-context.xml" and "/extended-context.xml"
// in the root of the classpath
@ContextConfiguration("/extended-context.xml")
public class ExtendedTest extends BaseTest {
   // class body...
}

 

2. spring bean的注入及使用

 

@RunWith(SpringJUnit4ClassRunner.class)
// specifies the Spring configuration to load for this test fixture
@ContextConfiguration("daos.xml")
public final class HibernateTitleDaoTests {
// this instance will be dependency injected by type
@Autowired
private HibernateTitleDao titleDao;
public void testLoadTitle() throws Exception {
   Title title = this.titleDao.loadTitle(new Long(10));
    assertNotNull(title);
}
}
