Testability + +**Domain services:** +- Tested in isolation +- No mocking required +- Fast, focused unit tests + +**BeerProvider:** +- Integration tests verify orchestration +- Services can be mocked if needed +- Tests focus on state management + +### 4. Reusability + +Domain services can be used: +- By BeerProvider (current usage) +- By widgets directly (future possibility) +- By other providers (if app grows) +- In background isolates (for heavy processing) + +## Benefits of Domain Layer + +### 1. Easier Testing + +**Before:** +```dart +// Had to mock entire provider to test filtering +test('filters by category', () { + final provider = BeerProvider( + apiService: mockApi, + festivalService: mockFestival, + analyticsService: mockAnalytics, + ); + await provider.initialize(); + // ... complex setup ... + provider.setCategory('beer'); + expect(provider.drinks.length, 2); +}); +``` + +**After:** +```dart +// Simple, focused unit test +test('filters by category', () { + final service = DrinkFilterService(); + final result = service.filterByCategory(testDrinks, 'beer'); + expect(result, hasLength(2)); +}); +``` + +### 2. Better Maintainability + +Changes to filtering logic: +- **Before:** Modify `BeerProvider._applyFiltersAndSort()` (63 lines) +- **After:** Modify `DrinkFilterService` (focused, single responsibility) + +### 3. Code Reuse + +Domain services are reusable: +```dart +// In a widget that needs custom filtering +final filterService = DrinkFilterService(); +final filtered = filterService.filterBySearch(drinks, userQuery); +``` + +### 4. Reduced Coupling + +- UI depends on BeerProvider (state management) +- BeerProvider depends on domain services (business logic) +- Domain services depend on nothing (pure logic) + +## When to Add New Domain Services + +Create a new domain service when: +1. **Business logic gets complex** (>20 lines) +2. **Logic is reused** in multiple places +3. **Logic is independent** of state management +4. **You want isolated testing** without mocking + +Examples of good candidates: +- `DrinkRecommendationService` - Personalized recommendations +- `DrinkStatisticsService` - Calculate stats (avg ABV, etc.) +- `DrinkValidationService` - Validate drink data + +## Testing Strategy + +### Unit Tests (Domain Services) + +**Focus:** Business logic correctness +**Location:** `test/domain/services/` +**Characteristics:** +- Fast execution (<1ms per test) +- No mocks required +- Test edge cases exhaustively + +### Integration Tests (BeerProvider) + +**Focus:** State management and orchestration +**Location:** `test/beer_provider_test.dart` +**Characteristics:** +- Test that services are called correctly +- Test state changes (loading, errors) +- Test that notifyListeners is called +- Can mock services if needed + +### Widget Tests (UI) + +**Focus:** User interactions +**Location:** `test/screens/`, `test/widgets/` +**Characteristics:** +- Test that UI responds to provider state +- Test user interactions trigger provider methods + +## Code Organization + +``` +lib/domain/ +└── services/ + ├── drink_filter_service.dart + ├── drink_sort_service.dart + └── services.dart # Barrel export + +test/domain/ +└── services/ + ├── drink_filter_service_test.dart + └── drink_sort_service_test.dart +``` + +## Future Enhancements + +Potential extensions to the domain layer: + +### 1.
