如何在服务层为@Transactional 时回滚单元测试
How to rollback unit test while service layer is @Transactional
我正在使用 Spring Boot 1.5.2.RELEASE 并且我的服务 classes 带有
注释
@Service
@Transactional(rollbackFor = Exception.class)
我的单元测试 class 注释为：
@RunWith(SpringRunner.class)
@SpringBootTest
我希望在测试完成后回滚通过单元测试方法在数据库中所做的更改。
建议的解决方案之一 是在测试 class 上添加 @Transactional 注释，我试过了但是这个解决方案产生了一些问题，是吗有时测试事务会在服务事务完成之前回滚（即使没有抛出任何异常！）。
回滚测试还有其他好的方案吗？
如果没有更改默认行为，所有更改都将回滚。而且你没有 类 / transaction propagation level = REQUIRES_NEW 的方法，因为它启动独立事务并且可以与外部事务独立提交或回滚
Transaction rollback and commit behavior
By default, test transactions will be automatically rolled back after
completion of the test; however, transactional commit and rollback
behavior can be configured declaratively via the @Commit and @Rollback
annotations.
@Rollback
@Rollback indicates whether the transaction for a transactional test
method should be rolled back after the test method has completed. If
true, the transaction is rolled back; otherwise, the transaction is
committed (see also @Commit). Rollback semantics for integration tests
in the Spring TestContext Framework default to true even if @Rollback
is not explicitly declared.
When declared as a class-level annotation, @Rollback defines the
default rollback semantics for all test methods within the test class
hierarchy. When declared as a method-level annotation, @Rollback
defines rollback semantics for the specific test method, potentially
overriding class-level @Rollback or @Commit semantics.
在测试 class 上带有 @Transactional 的解决方案是执行此操作的标准方法。 Spring Tx 不可能突然回滚事务，所以我建议仔细研究您遇到的问题，而不是发明其他解决方案。

您的评论：
sometimes the test transaction is rolled back (even without no
exceptions thrown !) before the service transaction is completed !
对我来说没有意义。回滚了怎么知道 txn 完成了没有？异常对于测试来说并不重要，正如我在上面引用的文档。
