Test ran before ServerStartupEvent

[hantsy]

Expected Behavior

I tried to convert one of my micronaut project to use test-resource instead of the original test containers.

There is a simple integration test like this.

//  transactional = true will throw:
//  Transaction mode is not supported when the synchronous transaction manager is created using Reactive transaction manager!
@MicronautTest(application = Application.class, transactional = false)
@Slf4j
class ApplicationTest {

    @Inject
    EmbeddedApplication<?> application;

    @Inject
    @Client("/customers")
    ReactorHttpClient client;

    @Test
    void testItWorks() {
        Assertions.assertTrue(application.isRunning());
    }

    @Test
    public void getAllCustomers() {
        log.debug("get all customers...");
        var request = HttpRequest.GET("");
        client.exchange(request, Argument.listOf(Customer.class))
                .log()
                .as(StepVerifier::create)
                .consumeNextWith(res -> {
                    assertEquals(HttpStatus.OK, res.getStatus());
                    assertThat(res.body()).anyMatch(customer -> customer.name().equals("Jack"));
                })
                .verifyComplete();
    }

}

I use singleton bean to initialize some sample data,

@Singleton
@Requires(notEnv = "mock")
@RequiredArgsConstructor
@Slf4j
public class SampleDataInitializer {
    private final CustomerRepository customers;

    @EventListener()
    public void init(ServerStartupEvent event) {
        customers.deleteAll().then()
                .thenMany(customers.saveAll(
                                List.of(
                                        Customer.of("Jack", 20, Address.of("test", "NY", "210000")),
                                        Customer.of("Rose", 19, Address.of("test", "Boston", "210000"))
                                )
                        )
                )
                .subscribe(
                        data -> log.debug("saved data: {}", data),
                        error -> log.error("error: {}", error),
                        () -> log.debug("done initialization")
                );
    }
}

What I expected is initializing the sample and verify data in the it tests.

Actual Behaviour

Obviously, the tests ran before the ServerStartupEvent.
