This commit introduces a suite of unit tests for the Vue.js frontend,
significantly improving code coverage and reliability.
Key areas covered:
- **Setup**: Configured Vitest and @vue/test-utils.
- **Core UI Components**: Added tests for SocialLoginButtons and NotificationDisplay.
- **Pinia Stores**: Implemented tests for auth, notifications, and offline stores,
including detailed testing of actions, getters, and state management.
Offline store tests were adapted to its event-driven design.
- **Services**:
- `api.ts`: Tested Axios client config, interceptors (auth token refresh),
and wrapper methods.
- `choreService.ts` & `groupService.ts`: Tested all existing service
functions for CRUD operations, mocking API interactions.
- **Pages**:
- `AccountPage.vue`: Tested rendering, data fetching, form submissions
(profile, password, preferences), and error handling.
- `ChoresPage.vue`: Tested rendering, chore display (personal & grouped),
CRUD modals, and state handling (loading, error, empty).
- `LoginPage.vue`: Verified existing comprehensive tests.
These tests provide a solid foundation for frontend testing. The next planned
step is to enhance E2E tests using Playwright.
