java测试注解(@RunWith(value = SpringJUnit4ClassRunner.class) )

转自：http://blog.csdn.net/generalyy0/article/details/6955752

知识点一：

@Transactional//默认只有runtime（运行时）异常回滚
@Transactional(rollbackFor = Exception.class)//表示抛出Exception异常后，回滚

 

知识点二：

在测试类里测试时需要用到的注解：

注：测试一定要保证：方法里的每一种情况到被测试到，也就是代码的覆盖率达到100%。

//测试时需要的

@RunWith(value = SpringJUnit4ClassRunner.class) //在使用所有注释前必须使用@RunWith(SpringJUnit4ClassRunner.class),让测试运行于spring测试环境
@ContextConfiguration(locations = {"classpath:/com/security/resource/spring/context/application/applicationContext.xml"} , loader = GenericXmlContextLoader.class)//【@ContextConfiguration 用来指定加载的Spring配置文件的位置,会加载默认配置文件,  

@ContextConfiguration 注解有以下两个常用的属性：locations：可以通过该属性手工指定 Spring 配置文件所在的位置，可以指定一个或多个 Spring 配置文件用，分开。如下所示： @ContextConfiguration(locations={“aa/aa.xml”,” aa/bb.xml”})

inheritLocations：是否要继承父测试用例类中的 Spring 配置文件，默认为 true。】

 

@DirtiesContext(classMode = ClassMode.AFTER_CLASS)  //@DirtiesContext 在测试方法上出现这个注解时，表明底层Spring容器在该方法的执行中被“污染”，从而必须在方法执行结束后重新创建（无论该测试是否通过）。

@TransactionConfiguration( transactionManager = "transactionManager" , defaultRollback = false) //【@TransactionConfiguration 为配置事务性测试定义了类级别的元数据。PlatformTransactionManager默认的实例叫transactionManager， 如果需要的PlatformTransactionManager不是“transactionManager”的话，那么可以显式配置驱动事务的PlatformTransactionManager的bean的名字。此外， 可以将defaultRollback标志改为false，表示不回滚。通常， @TransactionConfiguration与@ContextConfiguration搭配使用。

@ContextConfiguration
@TransactionConfiguration(transactionManager="transactionManager", defaultRollback=false)】

@Transactional //开启类级别的事物
public class TestSecurityPermissionService {

//注解生成SecurityPermissionI 的代理
 @Autowired
 SecurityPermissionI securityPermissionI;
