It seems to be unable to mock navigator interactions when code in tests depends on types that are not publicly visible.
It's not uncommon that the Flutter SDK uses internal types that cannot be used outside the sdk. E.g. trying to test that DropdownButton pushes a dropdown menu will throw due to the when method generic type param that cannot be stubbed.
Attempting the above will fail with:
Exception has occurred.
TestFailure (No matching calls. All calls: MockNavigator.canPop(), MockNavigator.push<_DropdownRouteResult<String>>(_DropdownRoute<String>(RouteSettings(none, null), animation: null))
Mock navigator should expose a way of working around internal types (or maybe there already is one that I'm unaware of).
Describe the bug
When trying to use mockingjay on a brand new project, running on my Windows machine, I get fatal error.
To Reproduce
On a brand new Flutter project, create a widget test file with the code example that can be found on the mockingjay README:
import 'package:flutter/material.dart';
import 'package:flutter_test/flutter_test.dart';
import 'package:mockingjay/mockingjay.dart';
class MyHomePage extends StatelessWidget {
const MyHomePage({super.key});
@override
Widget build(BuildContext context) {
return Scaffold(
body: TextButton(
onPressed: () => Navigator.of(context).push(MySettingsPage.route()),
child: const Text('Navigate'),
),
);
}
}
class MySettingsPage extends StatelessWidget {
const MySettingsPage({super.key});
static Route<void> route() {
return MaterialPageRoute(
builder: (_) => const MySettingsPage(),
settings: const RouteSettings(name: '/settings'),
);
}
@override
Widget build(BuildContext context) {
return const Scaffold();
}
}
void main() {
testWidgets('pushes SettingsPage when TextButton is tapped', (tester) async {
final navigator = MockNavigator();
when(() => navigator.push<void>(any())).thenAnswer((_) async {});
await tester.pumpWidget(
MaterialApp(
home: MockNavigatorProvider(
navigator: navigator,
child: const MyHomePage(),
),
),
);
await tester.tap(find.byType(TextButton));
verify(
() => navigator.push<void>(
any(
that: isRoute<void>(
whereName: equals('/settings'),
),
),
),
).called(1);
});
}Then run the test and check that in fact it doesn't work with the following stack trace:
$ flutter test
00:05 +0: pushes SettingsPage when TextButton is tapped

00:05 +0 -1: pushes SettingsPage when TextButton is tapped [E]
Test failed. See exception logs above.
The test description was: pushes SettingsPage when TextButton is tapped
To run this test again: C:\Users\arthu\flutter\bin\cache\dart-sdk\bin\dart.exe test C:/Users/arthu/Documents/flutter/navalia/hello_world/test/widget_test.dart -p vm --plain-name "pushes SettingsPage when TextButton is tapped"
00:06 +0 -1: Some tests failed.Expected behavior
Expect the test case to run successfully.
Additional context
That problem was found on a much larger project with other developers that use a different OS other than Windows. Recently a new developer joined the team and is facing this issue with even simple "hello world" projects.
We have a missing Github release for the 0.4.0 version.
There's a new mocktail version out (yay!). Unfortunately I can't use it because mockingjay still has a dep on mocktail: ^0.3.0.
Can you please release a new version of mockingjay with updated deps?
Describe the bug
If a project has build_runner 2.3.2 (latest of writing), mockingjay 0.3.0 won't work
Expected behavior
flutter pub get should work
logs
The current Dart SDK version is 2.17.1.
Because test >=1.16.6 <1.17.10 depends on analyzer ^1.0.0 and test >=1.17.10 <1.20.0 depends on analyzer >=1.0.0 <3.0.0, test >=1.16.6 <1.20.0 requires analyzer >=1.0.0 <3.0.0.
And because test >=1.20.0 <1.21.0 depends on analyzer >=2.0.0 <4.0.0 and test >=1.21.5 requires SDK version >=2.18.0-146.0.dev <3.0.0, test >=1.16.6 <1.21.0-∞ or >=1.21.5 requires analyzer >=1.0.0 <4.0.0.
And because test >=1.21.4 <1.21.5 depends on test_core 0.4.16 and test >=1.21.3 <1.21.4 depends on test_core 0.4.15, test >=1.16.6 <1.21.0-∞ or >=1.21.3 requires analyzer >=1.0.0 <4.0.0 or test_core 0.4.15 or 0.4.16.
And because test >=1.21.2 <1.21.3 depends on test_core 0.4.14 and test >=1.21.0 <1.21.2 depends on test_core 0.4.13, test >=1.16.6 requires analyzer >=1.0.0 <4.0.0 or test_core 0.4.13 or 0.4.14 or 0.4.15 or 0.4.16.
And because build_runner >=2.2.1 depends on analyzer >=4.4.0 <6.0.0 and mockingjay >=0.2.0 depends on test ^1.17.0, if build_runner >=2.2.1 and mockingjay >=0.2.0 then test_core 0.4.13 or 0.4.14 or 0.4.15 or 0.4.16.
And because test_core >=0.3.23 <0.4.17 depends on frontend_server_client ^2.1.0 and build_runner >=2.3.1 depends on frontend_server_client ^3.0.0, build_runner >=2.3.1 is incompatible with mockingjay >=0.2.0.
So, because sofi_x_package depends on both build_runner ^2.3.2 and mockingjay ^0.3.0, version solving failed.
pub get failed (1; So, because sofi_x_package depends on both build_runner ^2.3.2 and mockingjay ^0.3.0, version solving failed.)
Additional context
Downgrading to build_runner 2.2.1 acts a workaround
Is your feature request related to a problem? Please describe.
This is not a feature request but please consider it as a question.
How to test the OpenContainer navigation using Mockingjay?
Describe the question
I have OpenContainer navigation in my project and I want to test this type of navigation. Can I use this package for testing this?
Hi,
It would be possible to make a version of the stable version (0.1.1) that updates the dependencies?
Hi, I'm using mockingjay in my project and using the Flutter 3.13.0 I have this problem below.
In the Flutter 3.10.0, my test run and work as expected.
This PR maybe can fix this:
thanks for the proposal, @erickzanardo. :)

Need to update to the latest versions of Flutter and Dart
The readme has install instructions for version 0.3.0.
Change it to instructions using dart pub add
Describe the bug
Mockingjay is dependent on mocktail 0.2.0 and cannot be used with 0.3.0
To Reproduce
Steps to reproduce the behavior:
Define dependencies:
dev_dependencies:
bloc_test: ^9.0.2
flutter_test:
sdk: flutter
mockingjay: ^0.2.0
mocktail: ^0.3.0See flutter packages get output:
Because app depends on mockingjay ^0.2.0 which depends on mocktail ^0.2.0, mocktail ^0.2.0 is required. So, because app depends on mocktail ^0.3.0, version solving failed.
Expected behavior
Packages should resolve successfully
I tried to use Mockingjay and used it according to the example, but all my tests failed. Well then, I copied the whole example into a new smalltest_test.dart file - but even the example fails.
I expected the example to be failsave... am I missing something?

Am I missing somethiing? If I change the example to not wrap the MaterialApp twice by just returning Builder widget I can than incorporate with using eBay's golden toolkit and possibly ebay's given when then.
Is there any desire reason to nestingMaterialApp twice?
Describe the bug
When I open a dialog with showDialog and I pop it, verify tells me it never called .pop while it did.
popping...
popped!

✓ MainApp can pop a normal widgetTo Reproduce
Reproducible example: https://github.com/egonm12/flutter_mockingjay/tree/main
void main() {
group(MainApp, () {
late MockNavigator mockNavigator;
setUp(() {
mockNavigator = MockNavigator();
when(() => mockNavigator.canPop()).thenReturn(true);

}Expected behavior
All tests pass
Is your feature request related to a problem? Please describe.
when writing code on IDE/code editor(VS Code or any other) for MockNavigatorProvider their suggestions or auto-completes with child as a first and navigator as a second but when user has sort_child_properties_last lint rule enabled then code editor hint lint problem and user needs to manually fix that every time after auto-completes or later.
Describe the solution you'd like
For MockNavigatorProvider - I would like to have navigator as a first and child as a last argument
Additional context
Is there any form to mock NavigatorState?
In my navigations tests with Navigator.of(context) the mock with mockingjay works fine, but some parts of my application uses NavigatorState and the mocks are not working as expected.
Future pushNamed(String routeName, {Object? arguments}) async => await _getCurrentState()!.pushNamed(routeName, arguments: arguments);
The _getCurrentState just return a NavigatorState.
When i run the test the behavior pushNamed are not overridden as expected.
var mockNavigator = MockNavigator();
when(() => mockNavigator.pushNamed(any())).thenAnswer((_) async => {});
v0.3.0-dev has been out for a month now, and it is looking stable so we can move that to stable release
