Test Examples

// Unit Test Example
test('should return hotel list when search is successful', () async {
  // Arrange
  when(() => mockRepository.fetchHotels(params: any(named: 'params')))
      .thenAnswer((_) async => expectedResponse);
  
  // Act
  final result = await useCase.call(params: searchParams);
  
  // Assert
  expect(result.items, equals(expectedHotels));
});

// Widget Test Example
testWidgets('should display hotel name and description', (tester) async {
  await tester.pumpWidget(createTestApp(
    child: HotelCard(hotel: testHotel, isFavorite: false, onFavoriteChanged: (_) {}),
  ));
