No GoRouter found in context in widget tests - flutter

Question

I'm trying to mock go_router in my widget tests but keep getting this error:
══╡ EXCEPTION CAUGHT BY GESTURE ╞═══════════════════════════════════════════════════════════════════
The following assertion was thrown while handling a gesture:
No GoRouter found in context
'package:go_router/src/router.dart':
Failed assertion: line 300 pos 12: 'inherited != null'
When the exception was thrown, this was the stack:
#2 GoRouter.of (package:go_router/src/router.dart:300:12)
#3 GoRouterHelper.pushNamed (package:go_router/src/misc/extensions.dart:50:16)
#4 _ProfileEditWidgetState._getSubmitButton.<anonymous closure>.<anonymous closure> (package:app/widgets/profile/profile_edit_widget.dart:236:33)
I'm using go_router 6.0.0
Here's what I have in my test:
final router = MockGoRouter();
when(router.pushNamed(any)).thenReturn(null);
await tester.pumpWidget(
MultiProvider(
providers: [
BlocProvider<ProfileBloc>(create: (context) => profileBloc),
],
child: MaterialApp(
locale: const Locale("en"),
home: InheritedGoRouter(
goRouter: router,
child: ProfileEditWidget(),
),
),
),
);
await tester.pump();
await tester.tap(find.byKey(const Key('btnSubmit')));
await tester.pump();
In my profile edit widget in the submit button on pressed this is what I have:
context.pushNamed(
VERIFY_PHONE,
queryParams: {
'updatedPhone': phone
},
)
There also seems to be no documentation on go to handle testing with go router

Answer 1

Try to change the MaterialApp to MaterialApp.router
And use GoRouter() instead of MockGoRouter()
import 'package:go_router/go_router.dart';
// GoRouter configuration
final _router = GoRouter(
routes: [
GoRoute(
path: '/',
builder: (context, state) => HomeScreen(),
),
],
);
class MyApp extends StatelessWidget {
#override
Widget build(BuildContext context) {
return MaterialApp.router(
routerConfig: _router,
);
}
}
