How to write integration test in provider

Question

Could not find appbar title "Exam Start"

await tester.pump(Duration(seconds: 1));
final titleFinder = find.text("Exam start");
expect(titleFinder, findsOneWidget);

my provider implementation is given below.

return MultiProvider(
      providers: [
        // Provider(create: (context) => RadioModel()),
        ChangeNotifierProvider(
          // Initialize the model in the builder. That way, Provider
          // can own Counter's lifecycle, making sure to call `dispose`
          // when not needed anymore.
          create: (context) => RadioModel(),
          //child: const MyApp(),
        ),
        ChangeNotifierProvider(
          // Initialize the model in the builder. That way, Provider
          // can own Counter's lifecycle, making sure to call `dispose`
          // when not needed anymore.
          create: (context) => CheckModel(),
          //child: const MyApp(),
        ),
       
      ],
  child: Scaffold(

`How can I get view(button image text or etc ) acccess from the inner of body container? I have a set of question and answer list in my widget, user have to select radiogroup/checkbutton/input test from multiple answer. If user finished one of them, he will get the access of the next question by pressing the next button. For integrating test first I have to find those answer view with title/id/key after that need to automically select one of them and press the next button. But unfortunately I couldn't get the view!!!
