# Test Coverage TODO
This document tracks test coverage improvements for DocuElevate. The goal is to improve overall coverage from 45% to 60%+, then iterate in 10% steps.
## Current Status
**Initial Coverage**: 45.09%
**Current Coverage**: 48.17%
**Progress**: +3.08%
**Target Coverage**: 60%+ (Phase 1), then 70%, 80%
**Remaining to target**: ~12%
## Completed Tests

10. **app/tasks/imap_tasks.py**: 0% → 15.35% (+15.35% from imports)
## Phase 2: Medium Priority (Target: 70%+)
### API Routes with Low Coverage

## Phase 3: Complex Integration Tests (Target: 80%+)
### Upload Task Modules (Currently 13-36%)
These require complex external service mocking:
- [ ] `app/tasks/upload_to_dropbox.py` (13.45%)
- [ ] `app/tasks/upload_to_google_drive.py` (36.00%)
- [ ] `app/tasks/upload_to_onedrive.py` (26.32%)
- [ ] `app/tasks/upload_to_nextcloud.py` (15.19%)
- [ ] `app/tasks/upload_to_paperless.py` (18.60%)
- [ ] `app/tasks/upload_to_email.py` (36.08%)
### Complex Background Tasks (0-36%)
- [ ] `app/tasks/check_credentials.py` (0%)
- Requires mocking multiple external services
- Test credential validation for each provider
- Test failure state management

### View Routes (25-61%)
- [ ] `app/views/status.py` (25.00%)

- [ ] `app/views/settings.py` (42.86%)
- [ ] `app/views/google_drive.py` (42.42%)
## Testing Strategy
### For Low-Hanging Fruits (Phase 1)
1. Focus on pure functions with minimal dependencies
2. Mock external services (OpenAI, Azure, cloud storage)
3. Test error paths and edge cases
4. Use pytest fixtures for common setup
### For Integration Tests (Phases 2-3)
1. Create comprehensive mocks for external services
2. Use pytest-mock for patching
3. Test async functions with pytest-asyncio
4. Use TestClient for API endpoint tests
5. Mock Redis, database, and Celery for task tests
## Coverage Goals by Phase
| Phase | Target Coverage | Status |
|-------|----------------|--------|
| Phase 1: Low-Hanging Fruits | 60% | In Progress |
| Phase 2: Medium Priority | 70% | Not Started |
| Phase 3: Complex Integration | 80% | Not Started |
## Notes
- Files with 100% coverage: Keep them at 100%
- Files with 90%+ coverage: Low priority for improvement
- Focus on business logic, not simple re-exports
- Mock external dependencies to avoid flaky tests
- All tests must pass CI/CD pipeline
- Maintain test execution time under 2 minutes for fast feedback
## Files Excluded from Coverage
These files are infrastructure/configuration and don't require high coverage:
- `migrations/*` - Database migrations (excluded in pytest.ini)
- `app/__init__.py` - Empty init files
- `app/*/__init__.py` - Package init files
## Running Tests
```bash
# Run all tests with coverage
pytest --cov=app --cov-report=term-missing
# Run tests for specific module
pytest tests/test_encryption.py -v
# Run tests with coverage report
pytest --cov=app --cov-report=html
open htmlcov/index.html
# Run only unit tests (fast)
pytest -m unit
# Run integration tests
pytest -m integration
```
## Contributing
When adding new code:
1. Write tests for new functionality
2. Aim for 80%+ coverage on new files
3. Update this TODO when completing test coverage work
4. Run coverage report before submitting PR
