### Question:
OvsdbManagersRemovedCommand extends AbstractTransactionCommand { private boolean checkIfManagerPresentInUpdatedManagersList(Manager removedManager) { for (Map.Entry<UUID, Manager> updatedManager : updatedManagerRows.entrySet()) { if (updatedManager.getValue().getTargetColumn().getData() .equals(removedManager.getTargetColumn().getData())) { return true; } } return false; } OvsdbManagersRemovedCommand(OvsdbConnectionInstance key,
            TableUpdates updates, DatabaseSchema dbSchema); @Override void execute(ReadWriteTransaction transaction);  }### Answer:
@SuppressWarnings("unchecked") @Test public void testCheckIfManagerPresentInUpdatedManagersList() throws Exception { Manager updatedManager = mock(Manager.class); updatedManagerRows = new HashMap<>(); UUID uuid = mock(UUID.class); updatedManagerRows.put(uuid, updatedManager); MemberModifier.field(OvsdbManagersRemovedCommand.class, "updatedManagerRows").set(ovsdbManagersRemovedCommand, updatedManagerRows); Column<GenericTableSchema, String> column = mock(Column.class); Manager removedManager = mock(Manager.class); when(removedManager.getTargetColumn()).thenReturn(column); when(updatedManager.getTargetColumn()).thenReturn(column); when(column.getData()).thenReturn(TARGET_COLUMN_DATA); assertEquals(true, Whitebox.invokeMethod(ovsdbManagersRemovedCommand, "checkIfManagerPresentInUpdatedManagersList", removedManager)); }
