Did you register |
How to register the AnnouncementBloc in the test? |
|
in your app you register AnnouncementBloc ? |
This is my simple test. Yes, I registered the block in my app void main() { testWidgets('Exist FloatingActionButton', (WidgetTester tester) async { }); |
|
you have to register your objects after the reset |
import 'package:flutter/material.dart'; void main() { }); Widget createWidgetForTesting({Widget child}) { testWidgets('Exist FloatingActionButton', (WidgetTester tester) async { }); and my error⬇ Testing started at 4:42 PM ... The relevant error-causing widget was: When the exception was thrown, this was the stack: ════════════════════════════════════════════════════════════════════════════════════════════════════ Test failed. See exception logs above. Please tell me how to register the object correctly in the test |

you have to do the reset and register inside your test like: |

Hello @escamoteur , More context:
Is it a bug or a feature? Why don't we leverage getIt in the main app? |

The problem is that the main app isn't executed inside of tests. What you can do is calling your registration function of tge main app in the setup function of the tests

… Hello @escamoteur ,
Why do we have to register dependencies again while we do this in the main app?
More context:
1. > main.dart
void main() { registerDependencies(); // Register dependency for GetIt runApp(MyApp()); }
2. > main_test.dart
`void main() {
testWidget('TEST', (tester) async {
await tester.pumpWidget(MyApp());
await tester.pumpAndSettle();
// We can not use GetIt to get this dependency value (we must re-register again before using it)
GetIt.I.get().value;
});
}`
Is it a bug or a feature? Why don't we leverage getIt in the main app?

Hello Mr, how about when we call the app main function inside testWidget? |

Hello Mr, how about when we call the app main function inside testWidget?
testWidget('TEST', (tester) async {
app.main(); // include register GetIt
// we still re-register GetIt.
});

You are right. It will work when I use app.main() instead of pumpWidget(MyApp()). |
You did not mention the widget test in the package description.
How can I solve my problem?
It displays this error when I run the widget test.
