### Question:
BaseConfiguration { public BufferFactory getBufferFactory() { return bufferFactory; } BaseConfiguration(ConfigurationContext configurationContext,
                             ParameterInclude parameters,
                             WorkerPool workerPool,
                             PassThroughTransportMetricsCollector metrics); void build(); WorkerPool getWorkerPool(int workerPoolCoreSize, int workerPoolMaxSize,
                                    int workerThreadKeepaliveSec, int workerPoolQueuLen,
                                    String threadGroupName, String threadgroupID); int getIOBufferSize(); WorkerPool getWorkerPool(); ConfigurationContext getConfigurationContext(); BufferFactory getBufferFactory(); PassThroughTransportMetricsCollector getMetrics(); Boolean isCorrelationLoggingEnabled(); boolean isPreserveHttpHeader(String headerName); List<String> getPreserveHttpHeaders();  }### Answer:
@Test public void testGetBufferFactory() throws Exception { Assert.assertNotNull("BufferFactor is null.", baseConfiguration.getBufferFactory()); Assert.assertTrue("Buffer isn't an instance of ControlledByteBuffer.", baseConfiguration.getBufferFactory().getBuffer() instanceof ControlledByteBuffer); }
