Can't get past splash screen after integration_test migration

flutter integration-testing splash-screen

Solution 1

Is this working for you?

import 'dart:io';
import 'package:flutter/widgets.dart';
import 'package:flutter_test/flutter_test.dart';
import 'package:integration_test/integration_test.dart';
import '../lib/main.dart' as app;

void main() {
  // Changing the `utilityPolicy`. Credits to: https://stackoverflow.com/a/68099497/8358501
  final binding = IntegrationTestWidgetsFlutterBinding.ensureInitialized() as IntegrationTestWidgetsFlutterBinding;
  binding.framePolicy = LiveTestWidgetsFlutterBindingFramePolicy.fullyLive;

  testWidgets('verify users', (WidgetTester tester) async {
    app.main();

    sleep(const Duration(seconds: 10));

    await tester.pumpAndSettle();

    final Finder menuButtonFinder = find.byKey(const Key('kKeyButtonMenu'));

    expect(menuButtonFinder, findsOneWidget);
  });
}

Solution 2

Besides what Nils suggested, I also had to add pumpAndSettle(Duration(seconds: 3)) or just pump(Duration(seconds: 3)) after running app.main().

I thought pumpAndSettle(Duration) would be the same as sleep(Duration) plus pumpAndSettle(), but with the latter commands my app was getting stuck on the splash screen.

So, for me the working code is:

import 'dart:io';
import 'package:flutter/widgets.dart';
import 'package:flutter_test/flutter_test.dart';
import 'package:integration_test/integration_test.dart';
import '../lib/main.dart' as app;

void main() {
  final binding = IntegrationTestWidgetsFlutterBinding.ensureInitialized() as IntegrationTestWidgetsFlutterBinding;
  binding.framePolicy = LiveTestWidgetsFlutterBindingFramePolicy.fullyLive;

  testWidgets('verify users', (WidgetTester tester) async {
    app.main();
    await tester.pumpAndSettle(Duration(seconds: 3));

    final Finder menuButtonFinder = find.byKey(const Key('kKeyButtonMenu'));

    expect(menuButtonFinder, findsOneWidget);
  });
}

    My integration tests were working with flutter_driver but after migrating to integration_test following the docs I can't get past my splash screen.

    Below is a simple test. Without using sleep I never get past the Test starting... screen, as others found here. With the sleep the test gets past Test starting... but then gets stuck at my splash screen. Not sure if it's related, but my auth screen is after my splash screen.

    import 'dart:io';
import 'package:flutter/widgets.dart';
import 'package:flutter_test/flutter_test.dart';
import 'package:integration_test/integration_test.dart';
import '../lib/main.dart' as app;

void main() {
  IntegrationTestWidgetsFlutterBinding.ensureInitialized();

  testWidgets('verify users', (WidgetTester tester) async {
    app.main();

    sleep(const Duration(seconds: 10));

    await tester.pumpAndSettle();

    final Finder menuButtonFinder = find.byKey(const Key('kKeyButtonMenu'));

    expect(menuButtonFinder, findsOneWidget);
  });
}

    Below is the output showing the fail
