Now that we are done with unit tests let’s explore widget testing. The main goal of widget testing is to test the application’s UI and check if it’s getting rendered as intended. The main difference between a Widget Test and an Integration Test is that in Widget Test, you are testing the application’s UI, and in Integration Test you are testing the UI and the functionality of the application.

void main() {

}
import 'package:flutter_test/flutter_test.dart';

void main() {

  testWidgets('Login Widget Test', (WidgetTester tester) async {

  });
}
testWidgets('Login Widget Test', (WidgetTester tester) async {
  await tester.pumpWidget(LoginScreen());
  expect(find.text('Login Screen'), findsOneWidget);
});
testWidgets('Login Widget Test', (WidgetTester tester) async {
  await tester.pumpWidget(MaterialApp(home: LoginScreen()));
  expect(find.text('Login Screen'), findsOneWidget);
});
 testWidgets('Login Widget Test', (WidgetTester tester) async {
    await tester.pumpWidget(
      ProviderScope(
        child: MaterialApp(
          home: LoginScreen(),
        ),
      ),
    );
    expect(find.text('Login Screen'), findsOneWidget);
  });
