### Question:
BaseConfiguration { public WorkerPool getWorkerPool(int workerPoolCoreSize, int workerPoolMaxSize, int workerThreadKeepaliveSec, int workerPoolQueuLen, String threadGroupName, String threadgroupID) { if (threadGroupName == null) { threadGroupName = PASSTHROUGH_THREAD_GROUP; } if (threadgroupID == null) { threadgroupID = PASSTHROUGH_THREAD_ID; } if (workerPoolCoreSize == 0) { workerPoolCoreSize = conf.getWorkerPoolCoreSize(); } if (workerPoolMaxSize == 0) { workerPoolMaxSize = conf.getWorkerPoolMaxSize(); } if (workerThreadKeepaliveSec == 0) { workerThreadKeepaliveSec = conf.getWorkerThreadKeepaliveSec(); } if (workerPoolQueuLen == 0) { workerPoolQueuLen = conf.getWorkerPoolQueueLen(); } return WorkerPoolFactory.getWorkerPool(workerPoolCoreSize, workerPoolMaxSize, workerThreadKeepaliveSec, workerPoolQueuLen, threadGroupName, threadgroupID); } 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 testGetWorkerPool() throws Exception { Assert.assertNotNull("Worker pool hasn't been initialized.", baseConfiguration.getWorkerPool()); }
@Test public void testDefaultWorkerPool() throws Exception { WorkerPool workerPool = baseConfiguration.getWorkerPool(0, 0, 0, 0, null, null); Assert.assertNotNull("Worker pool hasn't been initialized.", workerPool); }
