// This is a basic Flutter widget test. // To perform an interaction with a widget in your test, use the WidgetTester utility that Flutter // provides. For example, you can send tap and scroll gestures. You can also use WidgetTester to // find child widgets in the widget tree, read text, and verify that the values of widget properties // are correct. import 'package:flutter/material.dart'; import 'package:flutter_test/flutter_test.dart'; import '../lib/main.dart'; void main() { testWidgets('Counter increments smoke test', (WidgetTester tester) async { // Build our app and trigger a frame. await tester.pumpWidget(MyApp()); // Verify that our counter starts at 0. expect(find.text('0'), findsOneWidget); expect(find.text('1'), findsNothing); // Tap the '+' icon and trigger a frame. await tester.tap(find.byIcon(Icons.add)); await tester.pump(); // Verify that our counter has incremented. expect(find.text('0'), findsNothing); expect(find.text('1'), findsOneWidget); }); }
