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.
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;
...
}
