### Question:
BufferConverter { public NettyDataBufferFactory getDataBufferFactory() { return dataBufferFactory; } BufferConverter();  BufferConverter(NettyDataBufferFactory dataBufferFactory); NettyDataBufferFactory getDataBufferFactory(); DataBuffer toDataBuffer(Buffer buffer); Buffer toBuffer(DataBuffer dataBuffer);  }### Answer:
@Test public void shouldGetDataBufferFactory() { assertThat(converter.getDataBufferFactory()).isEqualTo(dataBufferFactory); }
