Insert test record for Spring Batch integration test with #Transactional(propagation = NOT_SUPPORTED) does not roll back - spring-batch

Question

I would like to insert a test record while testing my Spring Batch job.
Normally I'd annotate the test class with #Transactional, but that does not work with a test class that is annotated with #SpringBatchTest.
#SpringBatchTest
#SpringBootTest
#Transactional
public class JobTest {
#Autowired
private JobLauncherTestUtils jobLauncherTestUtils;
#Autowired
private JdbcTemplate jdbcTemplate;
#Test
void someTest() throws Exception {
jdbcTemplate.update("insert into some_table (some_col1, some_col2) values ('foo', 'bar')");
jobLauncherTestUtils.launchJob();
}
}
Existing transaction detected in JobRepository. Please fix this and try again (e.g. remove #Transactional annotations from client).
java.lang.IllegalStateException: Existing transaction detected in JobRepository. Please fix this and try again (e.g. remove #Transactional annotations from client).
at org.springframework.batch.core.repository.support.AbstractJobRepositoryFactoryBean$1.invoke(AbstractJobRepositoryFactoryBean.java:177)
I have also tried #Transactional(propagation = NOT_SUPPORTED), but the record does not rollback. This was the suggestion in https://stackoverflow.com/a/46546171/10243546
I just want test records for the test, so I wasn't sure if this answer applies (https://stackoverflow.com/a/55001568/10243546) since this is just for a test.

Answer 1

You need to move test setup outside the test method, for example in a method annotated with #Before (JUnit 4) or #BeforeEach (JUnit 5). Something like:
#Before
public void initData() {
jdbcTemplate.update("insert into some_table (some_col1, some_col2) values ('foo', 'bar')");
}
#Test
void someTest() throws Exception {
jobLauncherTestUtils.launchJob();
}

Answer 2

I was able to get such a test running using TransactionTemplate in the test method:
#SpringBatchTest
class MyJobTest {
// [...]
#Autowired
PlatformTransactionManager txManager;
#Test
void some_test() {
// setup must be done in a custom transaction due too #SpringBatchTest
new TransactionTemplate(txManager).executeWithoutResult(t -> {
// use jdbcTemplate or entityManager to insert data
jdbcTemplate.update("insert into some_table (some_col1, some_col2) values ('foo', 'bar')");
});
jobLauncherTestUtils.launchJob();
}
}
