Story 1.10: Test Flutter Service Layer

Status: ready-for-dev

Story

As a developer, I want unit tests for the untested Flutter service-layer classes, so that business logic in the mobile app is validated independently of UI, network, and platform dependencies.

Acceptance Criteria

  1. AC1: UserService tests — test/services/user_service_test.dart covers all 6 methods (getCurrentUserInfo, getProfile, refreshUserData, updateAccountSettings, resetUserData, deleteAccount) with success (200) and error (non-200) paths. CurrentUserApi is mocked via a fake class.

  2. AC2: NotificationService tests — test/services/notification_service_test.dart verifies show(), success(), error(), info(), warning() emit correct NotificationEvent types on the stream, and validates message content and duration.

  3. AC3: I18nService tests — test/services/i18n_service_test.dart covers translate() with nested key resolution, English fallback for missing keys, argument substitution ({key} replacement), changeLanguage() with valid/invalid/same-locale cases, isRtl for Arabic vs English, and supportedLanguages completeness.

  4. AC4: ConnectivityService tests — test/services/connectivity_service_test.dart covers isOnline getter (hardware + override logic), toggleUserOfflineMode(), setUserOfflineMode(), recheckConnectivity() with DNS fallback, and stream emission. Connectivity plugin and InternetAddress.lookup are mocked.

  5. AC5: GenieAiConfig tests — test/services/genie_ai_config_test.dart covers load() parsing JSON config (title + icon path), idempotent loading (_loaded guard), and default values when config is malformed. rootBundle is mocked via TestWidgetsFlutterBinding.

  6. AC6: Shared test fixtures — test/fixtures/tokens.dart exports JWT token fixture factories. test/fixtures/api_responses.dart exports mock API response factories for user profile, account settings, and common backend responses.

  7. AC7: CI compatibility — All tests pass flutter test, produce JUnit XML via tojunit, and pass flutter analyze without warnings. No new dependencies are added to pubspec.yaml.

  8. AC8: Test count — At least 40 new tests across all test files, covering happy paths, error paths, and edge cases.
