### Question:
CombineNetworksOnly { public static SymMatrix combine(FeatureWeightMap weightMap, String namespace, long organismId, DataCache cache, ProgressReporter progress) throws ApplicationException { return combineWithAdder(weightMap, namespace, organismId, cache,progress); }  static SymMatrix combine(FeatureWeightMap weightMap, String namespace, long organismId, DataCache cache, ProgressReporter progress); static Logger logger; }### Answer:
@Test public void testCombineFeatures() throws ApplicationException { SymMatrix result = CombineNetworksOnly.combine(getFeatureWeightMap(getFeatures()), Data.CORE, config.getOrg1Id(), cacheBuilder.getCache(), NullProgressReporter.instance()); assertNotNull(result); }
