InkWell tap 的 Flutter 小部件测试失败

Question

我有一个这样的小部件测试，我可以用 actionKey 找到小部件，但敲击测试失败且 tapped tester.tap(...) 之后的值为假，我的测试有什么问题？

testWidgets('some test', (WidgetTester tester) async {
  final UniqueKey actionKey = UniqueKey();
  bool tapped = false;

  await tester.pumpWidget(MaterialApp(
    home: Scaffold(
      body: SlidableListItem(
        child: const ListTile(title: Text('item')),
        actions: <Widget>[
          InkWell(
            key: actionKey,
            child: const Text('action'),
            onTap: () => tapped = true,
          ),
        ],
      ),
    ),
  ));

  await tester.tap(find.byKey(actionKey));
  await tester.pump();

  expect(find.byKey(actionKey), findsOneWidget);
  expect(tapped, isTrue); <- failes
});

The following TestFailure object was thrown running a test:
  Expected: true
  Actual: <false>

Answer 1

点击 2 秒后尝试等待。

      await tester.pump(Duration(seconds: 2));

我认为它应该有效，因为它对我有用。
