### Question:
AccessOutputData extends BaseStepData implements StepDataInterface { void createDatabase( File databaseFile ) throws IOException { db = Database.create( databaseFile ); } AccessOutputData();  public Database db; public Table table; public List<Object[]> rows; public RowMetaInterface outputRowMeta; public boolean oneFileOpened; }### Answer:
@Test public void testCreateDatabase() throws IOException { assertNull( data.db ); data.createDatabase( mdbFile ); assertNotNull( data.db ); assertTrue( mdbFile.exists() ); assertNull( data.table ); data.truncateTable(); assertNull( data.table ); data.closeDatabase(); }
