I'm working with flutter test
. I want to test something after tap a widget
but I don't know how to find the button. Because I custom it rather than use Icon
or iconButton
. Also, I can't find it according to its text
because another widget has the same name. And also two InkWell
widget as you can see. My basic test code is here.
import 'package:flutter/cupertino.dart';
import 'package:flutter/material.dart';
import 'package:flutter_test/flutter_test.dart';
import 'package:grpc/grpc.dart';
import 'package:project/page/login.dart';
void main() {
testWidgets('login page test', (WidgetTester tester) async {
// Build our app and trigger a frame
await tester.pumpWidget(Login());
expect(find.text('login'), findsNWidgets(2));
expect(find.text('ID'), findsOneWidget);
expect(find.text('password'), findsOneWidget);
expect(find.text('end'), findsOneWidget);
// how to find my custom button
await tester.tap((find.byElementType(InkWell))); <- my question here
// test other things after tapping the button.
});
}
Instead of find.byElementType() use find.byType() .
So your code will be like this:
await tester.tap((find.byType(InkWell)));
Like this you have to mention key (key: const Key("btnLogin"),)
ElevatedButton(
key: const Key("btnLogin"),
onPressed: () {
_decrementCounter();
},
child: const Text(
" Login ",
textAlign: TextAlign.center,
style: TextStyle(color: Colors.white),
),
),
in Widget test
await tester.tap(find.byKey(const Key('btnLogin')));
await tester.pump();
InkWell(
key: const Key("btnLogin"),
child: ElevatedButton(
onPressed: () {
_decrementCounter();
},
child: const Text(
" Login ",
textAlign: TextAlign.center,
style: TextStyle(color: Colors.white),
),
),
),
Like this also we can do
await tester.tap(find.byKey(const Key('btnLogin')));
await tester.pump();
give a key name to your inkwell button like this.
- in your login screen.
InkWell(
key: const Key("login"),
child: ElevatedButton(
onPressed: () {
},
child: const Text(
" Login ",
textAlign: TextAlign.center,
style: TextStyle(color: Colors.white),
),
),
),
**- in your testing file**
var loginButton = find.byKey(const Key('login'));
await tester.tap(login);
