Im trying to test if password its obscured, this is how far I go, but seems like flutter can read a text even if it is obscured.

 testWidgets('password must be hidden', (WidgetTester tester) async {
  await tester.pumpWidget(wrapWithMaterialApp(child: page));

  await tester.enterText(find.byKey(Key('pass')), '1234');
  final passFinder = find.text('1234');
  expect(passFinder, findsNothing);

});

the test actually find '1234' but im completely sure its obscured.

Regardless of obscureText flag, entered text is always stored in memory (this parameter affects only visual representation). In tests we can only check this property as follows:

  testWidgets('TextField', (WidgetTester tester) async {
    await tester.pumpWidget(MyApp());
    final finder = find.byKey(Key('pass'));
    final input = tester.firstWidget<TextField>(finder);
    expect(input.obscureText, true);
  });

Testing TextFormField requires additional effort (TextField is child of TextFormField):

  testWidgets('TextFormField', (WidgetTester tester) async {
    await tester.pumpWidget(MyApp());
    final finder = find.descendant(
      of: find.byKey(Key('pass')),
      matching: find.byType(TextField),
    );
    final field = tester.firstWidget<TextField>(finder);
    expect(field.obscureText, true);
  });

  • Can we achieve the same with TextFormField doesn't seem like there is "obscureText" accessible with tester.firstWidget – ahmetakil Mar 10 '23 at 13:50
  • @ahmetakil `TextFormField` encapsulates `TextField` as child component, hence we should use `find.descendant`. – Spatz Mar 12 '23 at 10:23
