Mockito is calling real function instead of calling mocked function

[sbmvirdi]

I am trying to mock rest template function but its actually trying to call the actual endpoint instead of giving back mock response

@ExtendWith(SpringExtension.class)
@SpringBootTest(webEnvironment = SpringBootTest.WebEnvironment.RANDOM_PORT)
@activeprofiles("test")
@AutoConfigureMockMvc
@TestMethodOrder(MethodOrderer.OrderAnnotation.class)
@testcontainers

@MockBean
RestTemplate restTemplate;

        HttpHeaders headers = createHeader();
    String url = generateBaseUrlForUmsController(CREATE_USER, true);
    Mockito.when(restTemplate.postForEntity(
            eq(connectionConfig.getKeycloakTokenUrl()),
            any(HttpEntity.class),
            eq(AccessTokenResponse.class)
    )).thenReturn(ResponseEntity.ok().body(generateTokenResponse()));
    var request = CreateUserRequestDTO.builder()
            .firstName("John")
            .lastName("Doe")
            .teamId(UUID.fromString(teamId))
            .email("john@example.com")
            .build();
    var response = testRestTemplate.exchange(
            url,
            HttpMethod.POST,
            new HttpEntity<>(request, headers),
            UserResponseDTO.class
    );

    Assertions.assertEquals(HttpStatus.OK, response.getStatusCode());
    Assertions.assertNotNull(response.getBody());
    userId = response.getBody().getId().toString();
    
    Actual api called in my API
    
                ResponseEntity<AccessTokenResponse> response = restTemplate.postForEntity(apiUrl, entity, AccessTokenResponse.class);

Url i have verified that url passing to mockito and configured in API are same.
rest all params are also same.

getting exception
15:36:30.025 5b9d5379-9a6a-428a-82dd-37b254e2e925 [http-nio-auto-1-exec-9] ERROR c.l.ums.gateway.KeycloakService trace-id=5b9d5379-9a6a-428a-82dd-37b254e2e925 - Exception occurred due to: I/O error on POST request for "http://localhost:8080/realms/realm-name/protocol/openid-connect/token": Connection refused

I have configured localhost url in spring profile and it is trying to call the actual api so getting connection refused.
