How can I use @SpringBootTest(webEnvironment) with @DataJpaTest?

Question

I am trying to test a JAX-RS application but I'd rather not mock the data especially since there's a buildData method for an existing @DataJpaTest

Here's what I am trying so far:

@RunWith(SpringJUnit4ClassRunner.class)
@SpringBootTest(
    webEnvironment = SpringBootTest.WebEnvironment.RANDOM_PORT,
    classes = MyApp.class
)
@DirtiesContext
@DataJpaTest
public class MyResourceTest {

I get the following error

java.lang.IllegalStateException: Configuration error: found multiple declarations of @BootstrapWith for test class [app.MyResourceTest]: [@org.springframework.test.context.BootstrapWith(value=class org.springframework.boot.test.context.SpringBootTestContextBootstrapper), @org.springframework.test.context.BootstrapWith(value=class org.springframework.boot.test.autoconfigure.orm.jpa.DataJpaTestContextBootstrapper)]

The other ones I saw that are similar do not talk about the webEnvironment setting:

There is somewhat of a solution using @AutoConfigureTestDatabase but when I did that only the first one works because buildData is annotated with @Before (same as in @DataJpaTest) as I want the data to be pristine before each test so I can do failure scenarios.

Switching to @BeforeClass also won't work because I won't be able to use the @Autowire Repository objects.

The @DataJpaTest documentation states the following:

If you are looking to load your full application configuration, but use an embedded database, you should consider @SpringBootTest combined with @AutoConfigureTestDatabase rather than this annotation.

Keep in mind that @DataJpaTest is annotated with @Transactional and @DirtiesContext. So you may need those annotations along with @AutoConfigureTestDatabase.

Just updating my OP because I did what you had suggested already. – Archimedes Trajano Aug 22 '19 at 13:01

@ArchimedesTrajano I've just seen your update. I think `@Transactional` and `@DirtiesContext` should do the trick. – cassiomolin Aug 22 '19 at 13:04

Update your answer to say `@Transactional` and `@DirtiesContext` so I can accept it. – Archimedes Trajano Aug 22 '19 at 13:05
Actually there is one issue I found in that when I use restTemplate to get the data it seems there's nothing in the database, but that could be because I did buildData incorrectly. – Archimedes Trajano Aug 22 '19 at 13:22

Actually when doing the answer in https://stackoverflow.com/a/57609911/242042, it solves the immediate problem, but you won't be able to do any tests that involve the database using a REST client as @Transactional will prevent the data from being saved for the client to get.

To get this to work, @Transactional should not be used. Instead DirtiesContext.ClassMode.BEFORE_EACH_TEST_METHOD should be used instead. This dramatically slows down each test (as in 1 second to 10 seconds per test) but at least it works.

@RunWith(SpringJUnit4ClassRunner.class)
@SpringBootTest(
    webEnvironment = SpringBootTest.WebEnvironment.RANDOM_PORT,
    classes = MyApp.class
)
@DirtiesContext(classMode = DirtiesContext.ClassMode.BEFORE_EACH_TEST_METHOD)
@AutoConfigureTestDatabase
@AutoConfigureWebTestClient
public class MyResourceTest {

    @Autowired
    private TestRestTemplate restTemplate;

    ...

}

How can I use @SpringBootTest(webEnvironment) with @DataJpaTest?
