### Question:
DataSet extends BaseModel { public String getConnectionId() { return connectionId; } DataSet();  DataSet(JSONObject jsonObject); String getBasePath(); String getViewId(); String getConnectionId(); String getDescription(); Dule getDule(); String getSchema(); JSONObject getObservableSchema(); List<SchemaField> getFields(); List<SchemaField> getFields(FieldsFrom fieldsFrom); List<SchemaField> getFields(boolean useFlatNamesForLeafNodes); List<SchemaField> getFields(boolean useFlatNamesForLeafNodes, FieldsFrom fieldsFrom); SchemaRef getSchemaRef(); List<SchemaField> getFlattenedSchemaFields(); List<SchemaField> getFlattenedSchemaFields(FieldsFrom fieldsFrom); void matchFlattenedSchemaFields(Map<String, String> sdkFields); void matchFlattenedSchemaFields(Map<String, String> sdkFields, FieldsFrom fieldsFrom); Boolean getIsDuleEnabled(); FileDescription getFileDescription(); @Override DataSet build(JSONObject obj); void setSchema(String schema); void setSchemaRef(JSONObject jsonObject); List<SchemaField> getSchemaFieldsFromSchemaRef();  }### Answer:
@Test public void testGetConnectionId() { assertTrue(ds.getConnectionId().equalsIgnoreCase("conId")); }
