### Question:
BaseConfiguration { public PassThroughTransportMetricsCollector getMetrics() { return metrics; } 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 testGetMetrics() throws Exception { Assert.assertNotNull("Metrics hasn't been initialized.", baseConfiguration.getMetrics()); }
