RSS基于Spring2.5 Annotation的JUnit单元测试总结
Apr 14
敏捷开发强调测试先行。基于TDD(Test Driven Develop)的测试流程大体上分为：
* 编写测试代码
* 运行测试
* 完善(重构)代码
* 再测试
* 最终测试通过
基于Spring2.5 Annotation的单元测试还是比较简单的。这里要用到的JUnit4.4及以上版本的某些功能，大多数MyEclipse（如6.0/6.5/7）自带了JUnit3.8和JUnit4.3版本。所有为了能用Spring2.5提供的新功能，请重新下载JUnit并在MyEclipse中你的项目类路径中导入jar包，最新版本的JUnit4.5可以点击这里下载（下载的zip包可以解压出jar文件）
下面是一个完整的单元测试代码其中用到了很多Spring的Annotation功能。可以参看一下，对于某些暂时不想实现的功能，可以在方法上加@Ignore 标注
/**
*
* Description:
*
* @RunWith - JUnit annotation that specifies that the Spring class runner
* should be used for running the test.
* @ContextConfiguration - Specifies the location of your Spring application
* context xml file(s). This gets inherited by subclasses,
* so you can use it in a base class to configure all of
* the tests in your application.
* @Test - Indicates that the method should be run as a test. Note that although
* I used the pre JUnit 4 naming conventions (class names postfixed with
* "Test" and method names prefixed with "test"), this is not a
* requirement.
* @Ignore - When this annotation is added, the associated test method will not
* be run. This is a great alternative to commenting out the methods
* which was required prior to JUnit 4. In this case, the test would
* fail if the
* @Ignore annotation wasn't used because objectUnderTest.getSomethingFalse()
* does not equal true.
* @Autowired - Indicates that Spring should "wire" this dependency when
* initializing the test. In this case, a Spring bean named
* objectUnderTest will be provided.
*
*
* 要创建一个基于Spring2.5的JUnit4.4测试用例其实相当简单，主要进行以下几步的工作：
* (1)创建一个扩展自AbstractTransactionalJUnit4SpringContextTests的类，该基类是Spring2.5为方便在JUnit4环境进行事务测试的类，它还提供了一个simpleJdbcTemplate属性让你可以方便地操控数据库表，便于对测试数据进行有效的操作；
* (2)用@ContextLocation注解指定你要加载的Spring配置信息所在的位置；（默认的加载文件信息请参阅Spring
* Documentation）；
* (3)用@Autowired或@Resource注解注入你的Service接口，@Autowrired是指按类型将Spring
* Bean注入；而@Resource则按名称将Spring Bean注入。
* (4)用@Before准备待测试的数据，如果我们的数据库表结构没有任何数据，则可以在这里预先插入记录，以便进行单元测试，当整个测试完成后，这些数据都不会被保留在数据库中。
* (5)在需要进行测试的方法上使用JUnit4.4提供的@Test注解进行标示；
*
*
* Test类可以选择继承 extends AbstractTransactionalJUnit4SpringContextTests

@RunWith(SpringJUnit4ClassRunner.class)
// applicationContext*.xml这种匹配写法，是不支持的，有多少个配置文件，就引入多少个。
@ContextConfiguration(locations = { "classpath:/applicationContext.xml" })
// @TestExecutionListeners({DependencyInjectionTestExecutionListener.class})
public class ApartmentDAOImplTest {
private static Logger log = Logger.getLogger(ApartmentDAOImplTest.class);
@Autowired
private ApartmentDAOImpl apartmentDAOImpl;
// ApplicationContext ac = null;
//
// @Before
// public void setup() {
// ac = new ClassPathXmlApplicationContext("applicationContext.xml");
// }
@SuppressWarnings("unchecked")
@Test
public void testListAllApartment() {
//
List lst = apartmentDAOImpl.listAllApartment();
log.info(lst.size());
}
@Test
@Ignore
public void testFindApartmentByName() {
fail("Not yet implemented");
}
public ApartmentDAOImpl getApartmentDAOImpl() {
return apartmentDAOImpl;
}
public void setApartmentDAOImpl(ApartmentDAOImpl apartmentDAOImpl) {
this.apartmentDAOImpl = apartmentDAOImpl;
}
}
请在项目中增加Spring-test.jar, apache的commons-下的包最好都加上。(项目中你基本都能用上)
还要注意你的配置文件路径。
