### Question:
CpkCoreService { public RestRequestHandler getRequestHandler() { return Router.getBaseRouter(); } CpkCoreService( ICpkEnvironment environment ); CpkEngine getEngine(); CpkCoreService setEngine( CpkEngine engine ); void createContent( Map<String, Map<String, Object>> bloatedMap ); String getLocalizationResourceContent( String elementId, String resource ); void reload( OutputStream out, Map<String, Map<String, Object>> bloatedMap ); String reload( Map<String, Map<String, Object>> bloatedMap ); void refresh( OutputStream out, Map<String, Map<String, Object>> bloatedMap ); String refresh( Map<String, Map<String, Object>> bloatedMap ); void clearKettleResultsCache(); void status( OutputStream out, Map<String, Map<String, Object>> bloatedMap ); String status( Map<String, Map<String, Object>> bloatedMap ); void statusJson( OutputStream out, HttpServletResponse response ); String statusJson( HttpServletResponse response ); boolean hasElement( String elementId ); Collection<IElement> getElements(); void getElementsList( OutputStream out, Map<String, Map<String, Object>> bloatedMap ); String getElementsList(); IElement getDefaultElement(); RestRequestHandler getRequestHandler();  }### Answer:
@Test public void testGetRequestHandler() { RestRequestHandler requestHandler = cpkCore.getRequestHandler(); assertNotNull( requestHandler ); }
