I have issue with test cases on pinput widget

[yroza]

Describe the bug I implemented patrol(https://patrol.leancode.co/) package for perform the integration testing in my current project. when I write the test cases for test the Pinput widget so I am not able to enter text in Pinput widget.

Screenshots Here is my code for test the pinput widget

Pinput version: [e.g. 1.1.10]

Result of: flutter doctor --verbose

Hey @yroza @bartekpacia, can you confirm that this code snippet works for you as well?

import 'package:flutter/material.dart';
import 'package:flutter_test/flutter_test.dart';
import 'package:pinput/pinput.dart';

void main() {
  testWidgets('Can enter value', (WidgetTester tester) async {
    String? fieldValue;
    int called = 0;
    final controller = TextEditingController();
    final focusNode = FocusNode();

    await tester.pumpWidget(
      MaterialApp(
        home: Scaffold(
          body: Pinput(
            controller: controller,
            onChanged: (value) {
              fieldValue = value;
              called++;
            },
          ),
        ),
      ),
    );

    focusNode.requestFocus();
    await tester.pump();

    expect(fieldValue, isNull);
    expect(called, 0);

    await tester.enterText(find.byType(Pinput), '1111');
    await tester.testTextInput.receiveAction(TextInputAction.done);
    expect(fieldValue, equals('1111'));
    expect(called, 1);
  });
}

Thanks @Tkko, this code works in a widget test (when run with flutter test test/pinput_test.dart).

When I run it in a real app on the device (with flutter run test/pinput_test.dart), it also works:

pinput_test.dart.webm

I had to modify your test slightly to use setState(), so the changes made are visible:

Test code

```dart import 'package:flutter/material.dart'; import 'package:flutter_test/flutter_test.dart'; import 'package:pinput/pinput.dart'; void main() { testWidgets('Can enter value', (tester) async { String? fieldValue; var called = 0; final controller = TextEditingController(); final focusNode = FocusNode(); await tester.pumpWidget( MaterialApp( home: Scaffold( body: StatefulBuilder( builder: (context, setState) { return Pinput( controller: controller, onChanged: (value) { setState(() { fieldValue = value; called++; }); }, ); }, ), ), ), ); focusNode.requestFocus(); await tester.pump(); expect(fieldValue, isNull); expect(called, 0); await tester.enterText(find.byType(Pinput), '1111'); await tester.pumpAndSettle(Duration(seconds: 2)); await tester.testTextInput.receiveAction(TextInputAction.done); await tester.pumpAndSettle(Duration(seconds: 2)); expect(fieldValue, equals('1111')); expect(called, 1); }); } ```

@bartekpacia Perfect, I'm not sure how patrol works but Pinput uses an EditableText which is an underlying widget of TextField and CupertinoTextField so everything should work in the same way

[bartekpacia]

I'm curious whether you use a single EditableText for all of the number squares, or a single EditableText for each one of the number squares?

If you use a single EditableText for all, how does it work that you have a gap between the number squares?

[Tkko]

I use single EditableText Which is hidden under the boxes.

For any one facing the same issue: add one duration to pump method before calling await tester.enterText(find.byType(Pinput), '1111'); example: await tester.pump(Duration(milliseconds: 500));
