spring boot Dao test

i have a test case for dao implementation.
Test Class Code -

@RunWith(SpringRunner.class)
@RestClientTest({XyzDaoImpl.class})
@TestPropertySource(locations = "classpath:application-test.properties")
public class XyzDaoTest {

    @Autowired
    XyzDaoImpl xyzDaoImpl;

    @Test
    public void testGetXyzDetails(){
        assertThat(xyzDaoImpl.getXyzDetails("123", null)).isNotNull();
    }
}

xyzDaoImpl.getXyzDetails method implementation calls a backend using RestTemplate.
This test works fine when my config class code contains -

@Bean
public RestTemplate restTemplate() {
    return new RestTemplate();
}

but if i create the rest template using builder to set timeout etc , Test fails -

@Bean
public RestTemplate restTemplate(RestTemplateBuilder restTemplateBuilder) {
    return restTemplateBuilder
            .setConnectTimeout(timeout)
            .build();
}

Tried creating Bean using @Profile("test") default and @Profile("!test") - custom setting, still test fails.
Error is -

 testException = java.lang.AssertionError: No further requests expected: HTTP POST http://... url.
