DataJpaTest fails when updating to SpringBoot 1.5.5.RELEASE

I have a working test against an in-memory database with Spring Boot 1.5.4.RELEASE (or 2.0.0.M2) When I upgrade my project to 1.5.5.RELEASE (or 2.0.0.M3) the test fails because it cannot load the application context:

...

Basically, this is my test

@RunWith(SpringRunner.class)
@ContextConfiguration(classes = {SamePackageEntity.class})
@DataJpaTest
public class SamePackageEntityTest {

    @Autowired
    private SamePackageRepository samePackageRepository;

    @Test
    public void repositoryShouldHaveBeenInitialized() throws Exception {
        assertThat( samePackageRepository.count() ).isEqualTo( 0L );
    }

}

Is the problem in the update or in my Test?

I’ve added a pull request to spring-boot-issues that reproduces this problem

and: would you mind to reopen this issue, till it is fixed?

I still don’t believe there’s anything to fix here. Your application fits the description in this comment I made above. Specifically, there’s no class annotated with @EnableAutoConfiguration and you’re trying to use @DataJpaTest. That only worked previously due to a bug in 1.5.4 and earlier.

Replaced @SpringBootTest by @ContextConfiguration

That shouldn’t be necessary, and is rather odd as you’re referencing an entity in your @ContextConfiguration rather than a configuration class. Instead, you should add a main application class annotated with @SpringBootApplication (or @EnableAutoConfiguration) as shown in the following diff:

What would be your recommendation for auto configurations? Create my own one and exclude the other one e.g. JpaBaseConfiguration?

Upon closer inspection, I’ve just noticed that you’re subclassing JpaBaseConfiguration as you want to use Eclipse Link rather than Hibernate. For that purpose, it isn’t discouraged.

@wilkinsona Thanks for the tips! Replaced @SpringBootTest by @ContextConfiguration.
