Requests outgoing not logging in logbook zalando

Question

Why requests outgoing not logging with logbook ?

I have a unit test:

@Test
public void logRequestBodyTest() {

    Logbook logbook = Logbook.builder()
            .sink(new DefaultSink(
                    new DefaultHttpLogFormatter(),
                    new DefaultHttpLogWriter()
            ))
            .build();

    final LogbookClientFilter filter = new LogbookClientFilter(logbook);
    final LogbookHttpRequestInterceptor interceptor = new LogbookHttpRequestInterceptor(logbook);
    final ResteasyClient client = new ResteasyClientBuilder().register(filter).build();

    final Response response = client.target("http://localhost:15555/test/management").request().get();

}

logs:
