@EnableBatchProcessing doesn't work with @DataJpaTest

[arthurc]

If I use @EnableBatchProcessing on a configuration class and then try to write a test with @DataJpaTest, the test blows up when EntityManager#flush() is invoked and throws the following error:

javax.persistence.TransactionRequiredException: no transaction is in progress

I have put up a minimal project that illustrates a the issue over at https://github.com/arthurc/spring-boot-datajpatest-and-batch. Notice that if @EnableBatchProcessing is removed from https://github.com/arthurc/spring-boot-datajpatest-and-batch/blob/master/src/main/java/com/example/jpaandbatch/JpaAndBatchApplication.java then test (PersonTest) works fine.

The issue is in 1.5.8 and I've managed to backtrack the issue as far back as Spring Boot 1.4.2.

I would suggest to move @EnableBatchProcessing to another class and keep clean your Application.java class. Remember that any class annotated by @Configuration is scanned automatically if they share the same root package.

Regarding your tests, I think you should create the right annotation to load batch infrastructure to work with jpa.

[arthurc]

Yes, moving the @EnableBatchProcessing annotation to a separate class and excluding that from the test works. But I expected @DataJpaTest not to include batch stuff much the same way it isn't affected by web stuff for instance. The exception that was thrown doesn't really indicate that it was the @EnableBatchProcessing annotation that was the issue :)

What do you mean by creating the right annotation to load batch infrastructure?

True but the thing that's missing there is that @DataJpaTest (and others) need a source context to start your application. According to the documentation the default behaviour is to find a @SpringBootConfiguration which, in most cases, will be your @SpringBootApplication itself.

So @DataJpaTest will indeed only load JPA-related stuff. If you hardcode something else in your main Spring Boot app and you don't provide an alternative source for the context (see @SpringBootConfiguration and the doc I've mentioned) we're going to process with the main class with no way to exclude that.

@arthurc I've created a separate issue to improve that section with what I've just explained.

[arthurc]

Ahh, I see. I'll make sure not to clutter my main application class with additional @Enable*annotations. Thanks! :)

Hello I am facing the same issue.

I would like to test my batch by populating data and next run the job using jobLauncherTestUtils.

I am using TestEntityManager persistAndFlush method to save my data. It is working only if I remove all stuff from SpringBatch however I get this error javax.persistence.TransactionRequiredException: no transaction is in progress

I"ve defined @DataJpaTest, @AutoConfigureTestEntityManager, @EnableBatchProcessing in other configuration classes with no luck.

So basically, is it possible to use @DataJpaTest with batch ? If yes how can it be done ?

Thanks by advance.

Regards, Damien

I had a hard time trying to make Spring Batch work with JPA and Junit. The issue javax.persistence.TransactionRequiredException: no transaction is in progress has been occuring all the time.

[wilkinsona]

@pawelwloch There was nothing to resolve in Spring Boot itself. The problem above was that @EnableBatchProcessing was on the main application class so it was always being enabled even when only the JPA slice of the application was being tested. The solution is to move @EnableBatchProcessing onto a separate, Batch-focused configuration class. A recommendation to do this was added to the documentation as a result of this issue.
