# Test Strategy: Unified Task Reports by Type

## Overview
This feature implements a unified reporting center. Testing is split between Backend (Aggregation/Normalization) and Frontend (Unified UX/Type Profiles).

## Tiers & Fixtures
- **CRITICAL Modules**: `ReportsAggregationModule`, `ReportNormalizer`, `ReportsApiContract`, `UnifiedReportsPage`.
- **TEST_DATA**: Uses `mixed_task_reports` and `unknown_type_partial_payload` fixtures defined in `.ai/standards/semantics.md` (materialized in `backend/tests/fixtures/reports/fixtures_reports.json` and `frontend/src/lib/components/reports/__tests__/fixtures/reports.fixtures.js`).

## Test Suites

### Backend
1. **Contract Tests**: `backend/src/api/routes/__tests__/test_reports_api.py` (Pagination, Filters).
2. **Normalizer Tests**: `backend/src/services/reports/__tests__/test_report_normalizer.py` (Fallback logic).
3. **Detail Tests**: `backend/src/api/routes/__tests__/test_reports_detail_api.py`.
4. **Conformance**: `backend/src/api/routes/__tests__/test_reports_openapi_conformance.py`.

### Frontend
1. **UX Contract Tests**:
   - `frontend/src/lib/components/reports/__tests__/report_card.ux.test.js`
   - `frontend/src/lib/components/reports/__tests__/report_detail.ux.test.js`
2. **Integration Tests**:
   - `frontend/src/lib/components/reports/__tests__/reports_page.integration.test.js`
   - `frontend/src/lib/components/reports/__tests__/report_detail.integration.test.js`
3. **Unit Tests**:
   - `frontend/src/lib/components/reports/__tests__/report_type_profiles.test.js`
4. **Performance**:
   - `frontend/src/lib/components/reports/__tests__/reports_filter_performance.test.js`

## Execution
- Backend: `cd backend && .venv/bin/python3 -m pytest`
- Frontend: `cd frontend && npm test`
