### Question:
DataRegistryUtils { public DataModelCategory getMergeDataCategory(String layerId) { return mergeCat(layerId); } private  DataRegistryUtils(); static DataRegistryUtils getInstance(); DataModelCategory getMergeDataCategory(String layerId); static DataModelCategory mergeCat(String layerId); static void deposit(Toolbox tools, String layerId, List<MergedDataRow> data); static List<MergedDataRow> query(Toolbox tools, String layerId); static void delete(Toolbox tools, String layerId); static void deposit(Toolbox tools, DataModelCategory cat, PropertyDescriptor<R> prop, List<R> data); static List<R> query(Toolbox tools, DataModelCategory cat, PropertyDescriptor<R> prop); static void delete(Toolbox tools, DataModelCategory cat); static final PropertyDescriptor<MergedDataRow> MERGED_PROP_DESCRIPTOR; }### Answer:
@Test public void testGetMergeDataCategory() { DataModelCategory category = DataRegistryUtils.getInstance().getMergeDataCategory("iamunique"); assertEquals(new DataModelCategory("merged", "io.opensphere.merge.model.MergedDataRow", "iamunique"), category); }
