Problema com redis no docker.

Estou tendo o seguinte problema: Quando rodo a aplicação localmente, tudo funciona. Porém, quando rodo o teste, os métodos que interagem com o redis não funcionam. parece que não estão conseguindo se comunicar com o container criado no teste. se eu deixo o redis que uso em desenvolvimento ativo, os métodos funcionam. o que pode ser? parece que não está trocando o endereço nas properties durante os testes.

Classe Rating Controller test:

@Testcontainers @SpringBootTest(webEnvironment = SpringBootTest.WebEnvironment.RANDOM_PORT) class RatingControllerTest : DatabaseContainerConfiguration() {

@Autowired
private lateinit var webApplicationContext: WebApplicationContext

private lateinit var mockMvc: MockMvc

private var token: String? = null

@Autowired
private lateinit var jwtUtil: JWTUtil

companion object {
    private const val END_POINT_RATING = "/rating"
    private const val END_POINT_RATING_ID = END_POINT_RATING.plus("/%s")
}

@BeforeEach
fun setup() {

    token = generateTokenForTest()

    mockMvc = MockMvcBuilders.webAppContextSetup(webApplicationContext)
        .apply<DefaultMockMvcBuilder?>(
            SecurityMockMvcConfigurers.springSecurity()
        ).build()
}

@Test
fun `should return code 200 when rating is found`() {
    mockMvc.get(END_POINT_RATING_ID.format(1)).andExpect { status { is2xxSuccessful() } }
}


@Test
fun `teste df fdsf `() {
    mockMvc.get(END_POINT_RATING).andExpect { status { is2xxSuccessful() } }
}


@Test
fun `should return code 400 when request without token`() {
    mockMvc.delete(END_POINT_RATING_ID.format(1)).andExpect { status { is4xxClientError() } }
}

@Test
fun `should return code 400 when rating not found`() {
    mockMvc.get(END_POINT_RATING_ID.format(99)).andExpect { status { is4xxClientError() } }
}


@Test
fun `should return code 200 when correct token`() {
    mockMvc.delete("/rating/1") {
        headers { token?.let { this.setBearerAuth(it) } }
    }.andExpect { status { is2xxSuccessful() } }
}


private fun generateTokenForTest(): String? {
    val authorities = mutableListOf(br.com.leonardo.dicionarioAPI.model.Role(id = 1, "READ_WRITE"))
    return jwtUtil.generateToken("leonardo_spring_boot@gmail.com", authorities = authorities)
}

}
