SwipeTestHarness class

Wraps a SwipeActionCell with all required test ancestors.

Use this in widget tests instead of MaterialApp to avoid the overhead of full Material routing while still providing Directionality, MediaQuery, Localizations, and Material:

testWidgets('delete fires after undo window', (tester) async {
  bool deleted = false;
  await tester.pumpWidget(SwipeTestHarness(
    child: SwipeActionCell.delete(
      onDeleted: () => deleted = true,
      child: const ListTile(title: Text('Item')),
    ),
  ));
  await SwipeTester.swipeLeft(tester, find.byType(SwipeActionCell));
  // undo window: advance clock
  await tester.pump(const Duration(seconds: 6));
  expect(deleted, isTrue);
});
