### Question:
VertxClientHttpRequest extends AbstractClientHttpRequest { @Override public DataBufferFactory bufferFactory() { return bufferConverter.getDataBufferFactory(); } VertxClientHttpRequest(HttpClientRequest delegate, BufferConverter bufferConverter); @Override HttpMethod getMethod(); @Override URI getURI(); @Override DataBufferFactory bufferFactory(); @Override Mono<Void> writeWith(Publisher<? extends DataBuffer> chunks); @Override Mono<Void> writeAndFlushWith(Publisher<? extends Publisher<? extends DataBuffer>> chunks); @Override Mono<Void> setComplete();  }### Answer:
@Test public void shouldGetBufferFactory() { DataBufferFactory dataBufferFactory = request.bufferFactory(); assertThat(dataBufferFactory).isEqualTo(bufferConverter.getDataBufferFactory()); }
