### Question:
TargetConfiguration extends BaseConfiguration { public void build() throws AxisFault { super.build(); maxConnections = conf.getIntProperty(PassThroughConfigPNames.MAX_CONNECTION_PER_HOST_PORT, Integer.MAX_VALUE); preserveUserAgentHeader = conf.isPreserveUserAgentHeader(); preserveServerHeader = conf.isPreserveServerHeader(); populatePreserveHttpHeaders(conf.getPreserveHttpHeaders()); } TargetConfiguration(ConfigurationContext configurationContext,
                               ParameterInclude parameters,
                               WorkerPool pool,
                               PassThroughTransportMetricsCollector metrics,
                               ProxyAuthenticator proxyAuthenticator); void build(); HttpParams getHttpParams(); IOReactorConfig getIOReactorConfig(); HttpProcessor getHttpProcessor(); ProxyAuthenticator getProxyAuthenticator(); int getMaxConnections(); TargetConnections getConnections(); void setConnections(TargetConnections connections);  }### Answer:
@Test public void testBuild() throws Exception { Assert.assertNotNull("Building base configuration isn't successful.", targetConfiguration); }
