- **Configurations:** Test minimum `SECRET_KEY` length validation to prevent weak JWT signing keys. Validate proper handling of secure defaults.
- **Permissions:** Add tests for inactive user blocking, API access control, and superuser privilege escalation across organizational roles.
- **Authentication:** Test logout safety, session revocation, token replay prevention, and defense against JWT algorithm confusion attacks.
- Include `# pragma: no cover` for unreachable defensive code in security-sensitive areas.
- Deleted `test_crud_base.py`, `test_crud_error_paths.py`, and `test_organization_async.py` due to the removal of corresponding deprecated CRUD implementations.
- Improved codebase maintainability and reduced test suite noise by eliminating obsolete test files.
- Updated `verify_password` and `get_password_hash` to their async counterparts to prevent event loop blocking.
- Replaced N+1 query patterns in `admin.py` and `session_async.py` with optimized bulk operations for improved performance.
- Enhanced `user_async.py` with bulk update and soft delete methods for efficient user management.
- Added eager loading support in CRUD operations to prevent N+1 query issues.
- Updated test cases with stronger password examples for better security representation.
- Deleted outdated backend test cases (`test_auth.py`, `test_rate_limiting.py`, `test_users.py`) to clean up deprecated test structure.
- These tests are now redundant with newer async test implementations and improved coverage.
- Refactored all `password reset` and `auth dependency` tests to utilize async patterns for compatibility with async database sessions.
- Enhanced test fixtures with `pytest-asyncio` to support asynchronous database operations.
- Improved user handling with async context management for `test_user` and `async_mock_user`.
- Introduced `await` syntax for route calls, token generation, and database transactions in test cases.
- Introduced session management endpoints to list, revoke, and cleanup sessions per user.
- Added cron-based job for periodic cleanup of expired sessions.
- Implemented `CRUDSession` for session-specific database operations.
- Integrated session cleanup startup and shutdown events in the application lifecycle.
- Enhanced CORS configuration to include `X-Device-Id` for session tracking.
- Added comprehensive integration tests for multi-device login, per-device logout, session listing, and cleanup logic.
- Introduced unit tests for `EmailService` covering `ConsoleEmailBackend` and `SMTPEmailBackend`.
- Added tests for password reset request and confirmation endpoints, including edge cases and error handling.
- Implemented soft delete CRUD tests to validate `deleted_at` behavior and data exclusion in queries.
- Enhanced API tests for email functionality and user management workflows.
This commit introduces a suite of tests for user models, schemas, CRUD operations, and authentication services. It also adds utilities for in-memory database setup to support these tests and updates environment settings for consistency.
