### Question:
CgmesDLModel { public PropertyBags getBusesDiagramData() { LOG.info("Querying triple store for buses diagram data"); return queryTripleStore(BUS_DIAGRAM_DATA_QUERY_KEY); } CgmesDLModel(TripleStore tripleStore);  CgmesDLModel(TripleStore tripleStore, QueryCatalog queryCatalog); PropertyBags getTerminalsDiagramData(); PropertyBags getBusesDiagramData(); PropertyBags getBusbarsDiagramData(); PropertyBags getLinesDiagramData(); PropertyBags getGeneratorsDiagramData(); PropertyBags getLoadsDiagramData(); PropertyBags getShuntsDiagramData(); PropertyBags getSwitchesDiagramData(); PropertyBags getTransformersDiagramData(); PropertyBags getHvdcLinesDiagramData(); PropertyBags getSvcsDiagramData(); PropertyBags getTerminals(); PropertyBags getBusbarNodes(); PropertyBags getVoltageLevelDiagramData(); Map<String, Set<String>> findCgmesConnectivityNodesSwitchesForks(); static final String TERMINAL_DIAGRAM_DATA_QUERY_KEY; static final String BUS_DIAGRAM_DATA_QUERY_KEY; static final String BUSBAR_DIAGRAM_DATA_QUERY_KEY; static final String LINE_DIAGRAM_DATA_QUERY_KEY; static final String GENERATOR_DIAGRAM_DATA_QUERY_KEY; static final String LOAD_DIAGRAM_DATA_QUERY_KEY; static final String SHUNT_DIAGRAM_DATA_QUERY_KEY; static final String SWITCH_DIAGRAM_DATA_QUERY_KEY; static final String TRANSFORMER_DIAGRAM_DATA_QUERY_KEY; static final String HVDC_LINE_DIAGRAM_DATA_QUERY_KEY; static final String SVC_DIAGRAM_DATA_QUERY_KEY; static final String TERMINALS_QUERY_KEY; static final String BUSBAR_NODES_QUERY_KEY; static final String FORK_CONNECTIVITY_NODES_QUERY_KEY; static final String VOLTAGELEVEL_DIAGRAM_DATA_QUERY_KEY; static final String VOLTAGELEVEL_NO_SWITCHES_DIAGRAM_DATA_QUERY_KEY; static final String MODEL_DESCRIPTION; static final String MODEL_DEPENDENT_ON; static final String MODEL_VERSION; static final String MODEL_PROFILE; static final String MODEL_CREATED; static final String MODEL_SCENARIO_TIME; static final String IDENTIFIED_OBJECT_NAME; static final String ORIENTATION; static final String IDENTIFIED_OBJECT; static final String DIAGRAM; static final String DIAGRAM_OBJECT_STYLE; static final String DIAGRAM_OBJECT; static final String DIAGRAM_NAME; }### Answer:
@Test public void getBusesDiagramData() { assertEquals(busesPropertyBags, cgmesDLModel.getBusesDiagramData()); removeQueryCatalogKey(CgmesDLModel.BUS_DIAGRAM_DATA_QUERY_KEY); assertEquals(new PropertyBags(), cgmesDLModel.getBusesDiagramData()); }
