Spring Boot 3 + Testcontainers: Integration tests are being ignored without explicit error

I'm running integration tests with MySQLContainer and @ServiceConnection, but JUnit just marks them as "ignored/skipped" and I don't know what to do.

IT Class:

@Testcontainers @SpringBootTest(webEnvironment = SpringBootTest.WebEnvironment.RANDOM_PORT) public class ArtistControllerIT { @Autowired private TestRestTemplate testRestTemplate; @Container @ServiceConnection private static final org.testcontainers.mysql.MySQLContainer container = new MySQLContainer("mysql:8.0"); @LocalServerPort private int port; @Autowired private ArtistRepository artistRepository; @Test @DisplayName("List returns list of artist inside page object when successful") void list_ReturnsListOfArtistInsidePageObjet_WhenSuccessful() { Artist saved = artistRepository.save(ArtistCreator.createArtistToBeSaved()); PageableResponse<Artist> artistPage = testRestTemplate.exchange("/artists/list-artists", HttpMethod.GET, null, new ParameterizedTypeReference<PageableResponse<Artist>>() { }).getBody(); org.assertj.core.api.Assertions.assertThat(artistPage).isNotNull(); org.assertj.core.api.Assertions.assertThat(artistPage.getContent()).hasSize(1); org.assertj.core.api.Assertions.assertThat(artistPage.getContent().get(0).getName()).isEqualTo(saved.getName()); } @Test @DisplayName("Should return an artist dto by id when found one") void shouldReturnAnArtist_WhenPassedId() { Artist saved = artistRepository.save(ArtistCreator.createValidArtist()); testRestTemplate.exchange("/artists", HttpMethod.GET, null, saved.getClass(), saved.getId()); org.junit.jupiter.api.Assertions.assertEquals(1L, saved.getId(), "ID SHOULD BE 1"); } }

application-test.yml:

spring: datasource: url: jdbc:tc:mysql:8.4:///testdb driver-class-name: org.testcontainers.jdbc.ContainerDatabaseDriver

When I run docker-compose up via terminal, it works. But the tests don't even start. In the logs, I see:
