java - Transaction roll back is not working in test case in @Nested class of JUnit5

Question

I use spring-boot, JUnit5, Mybatis.

@SpringJUnitJupiterConfig(classes = {RepositoryTestConfig.class})
@MapperScan
@Rollback
@Transactional
public class TestClass {
    @Autowired
    private TestMapper testMapper;

    @BeforeEach
    void init() {
        User user = new User();
        testMapper.insert(user);    
    }

    @Test
    public void test1() {
        // (1) success rollback
    }

    @Nested
    class WhenExistData {
        @Test
        public void test2() {
            // (2) rollback not working
        }   
    }
}

(1) is working rollback. And the following log is output.

2017-05-26 22:21:29 [INFO ](TransactionContext.java:136) Rolled back transaction for test context ...

But, (2) is not working. I want to be able to roll back into @Nested.

Answer 1

This is to be expected: the Spring TestContext Framework has never supported "inheritance" for nested test classes.

Thus your "work around" is actually the correct way to achieve your goal at this point in time.

Note, however, that I may add support for "pseudo-inheritance" for nested test classes in conjunction with SPR-15366.
