I’m attempting to use the latest best practices for Spring Boot 3.x and TestContainers to integration test a MongoDB Repository. From a post on the Spring.io blog:

Under the covers, @ServiceConnection discovers the type of container that is annotated and creates a ConnectionDetails bean for it.
This replaces the need for the @DynamicPropertySource code, so you can just remove it.

Because I have several MongoDb integration tests, I setup an Abstract test class that creates a static MongoDb container under the hood:

@SpringBootTest
@Testcontainers(disabledWithoutDocker = true)
public abstract class MongoContainerTest {

    @Container
    @ServiceConnection
    static MongoDBContainer mongoDBContainer = new MongoDBContainer("mongo:7.0.9-rc1");
}

and then my test class extends it:

class RoleRepositoryTest extends MongoContainerTest {
    @Autowired
    RoleRepository roleRepository;

    private Role expectedRole;

    @BeforeEach
    void setUp() {
        roleRepository.deleteAll();
    }
    @Test
    void testFind() {...}

}

Run individually, these tests work just fine. However, when I attempt to run them all as part of a test suite from maven or Intellij, only the first MongoContainerTest child works, while the rest give an error:

I tried different things to get this configuration working. Such as setting the .withReuse(true) flag on. But I keep getting the same issue. I am guessing that after the first test runs the docker container shuts down and the next test is unable to open one. Any ideas here?
