## Main Test Scenario: Comparator Verification

**Goal:** Verify that searching for rates shows multiple companies with different prices.

**Test Route:** NLRTM (Rotterdam) → USNYC (New York)

**Search Parameters:**
- Volume: 25.5 CBM
- Weight: 3500 kg
- Pallets: 10
- Container Type: LCL

**Expected Results:**

| Rank | Company | Price (USD) | Transit | Notes |
|------|---------|-------------|---------|-------|
| 1️⃣ | **Test Maritime Express** | **$950** | 22 days | **BEST DEAL** ⭐ |
| 2️⃣ | SSC Consolidation | $1,100 | 22 days | Standard |
| 3️⃣ | TCC Logistics | $1,120 | 22 days | Mid-range |
| 4️⃣ | NVO Consolidation | $1,130 | 22 days | Standard |
| 5️⃣ | ECU Worldwide | $1,150 | 23 days | Slightly slower |

### ✅ Success Criteria

- [ ] All 5 companies appear in results
- [ ] Test Maritime Express shows lowest price (~10-20% cheaper)
- [ ] Each company has different pricing
- [ ] Prices are correctly calculated (freight class rule)
- [ ] Match scores are calculated (0-100%)
- [ ] Filters work correctly (company, price, transit, surcharges)
- [ ] Results can be sorted by price/transit/company/match score
- [ ] "All-in" badge appears for rates without surcharges

## Features to Test

### 1. Rate Search

**Endpoints:**
- POST `/api/v1/rates/search-csv`

**Test Cases:**
- ✅ Basic search returns results from multiple companies
- ✅ Results sorted by relevance (match score)
- ✅ Total price includes freight + surcharges
- ✅ Freight class pricing: max(volume × rate, weight × rate)

### 2. Advanced Filters

**12 Filter Types:**
1. Companies (multi-select)
2. Min volume CBM
3. Max volume CBM
4. Min weight KG
5. Max weight KG
6. Min price
7. Max price
8. Currency (USD/EUR)
9. Max transit days
10. Without surcharges (all-in only)
11. Container type (LCL)
12. Date range (validity)

**Test Cases:**
- ✅ Company filter returns only selected companies
- ✅ Price range filter works for USD and EUR
- ✅ Transit days filter excludes slow routes
- ✅ Surcharge filter returns only all-in prices
- ✅ Multiple filters work together (AND logic)

### 3. Comparator

**Goal:** Show multiple offers from different companies for same route

**Test Cases:**
- ✅ Same route returns results from 3+ companies
- ✅ Test Maritime Express appears with competitive pricing
- ✅ Price differences are clear (10-20% variation)
- ✅ Each company has distinct pricing
- ✅ User can compare transit times, prices, surcharges

### 4. CSV Configuration (Admin)

**Endpoints:**
- POST `/api/v1/admin/csv-rates/upload`
- GET `/api/v1/admin/csv-rates/config`
- DELETE `/api/v1/admin/csv-rates/config/:companyName`

**Test Cases:**
- ✅ Admin can upload new CSV files
- ✅ CSV validation catches errors (missing columns, invalid data)
- ✅ File size and type validation works
- ✅ Admin can view all configurations
- ✅ Admin can delete configurations

## Database Verification

After running migration, verify data in PostgreSQL:

```sql
-- Check CSV configurations
SELECT company_name, csv_file_path, is_active
FROM csv_rate_configs;

-- Expected: 5 rows
-- SSC Consolidation
-- ECU Worldwide
-- TCC Logistics
-- NVO Consolidation
-- Test Maritime Express
```

## CSV Files Location

All CSV files are in:
```
apps/backend/src/infrastructure/storage/csv-storage/rates/
├── ssc-consolidation.csv (25 rates)
├── ecu-worldwide.csv (26 rates)
├── tcc-logistics.csv (25 rates)
├── nvo-consolidation.csv (25 rates)
└── test-maritime-express.csv (25 rates) ⭐ FICTIONAL
```

## Price Calculation Logic

All prices follow the **freight class rule**:

```
freightPrice = max(volumeCBM × pricePerCBM, weightKG × pricePerKG)
totalPrice = freightPrice + surcharges
```

**Example:**
- Volume: 25 CBM × $35/CBM = $875
- Weight: 3500 kg × $2.10/kg = $7,350
- Freight: max($875, $7,350) = **$7,350**
- Surcharges: $0 (all-in price)
- **Total: $7,350**

## Match Scoring

Results are scored 0-100% based on:
1. **Exact port match** (50%): Origin and destination match exactly
2. **Volume match** (20%): Shipment volume within min/max range
3. **Weight match** (20%): Shipment weight within min/max range
4. **Pallet match** (10%): Pallet count supported

## Next Steps After Testing

1. ✅ **Verify all tests pass**
2. ✅ **Test frontend interface** (http://localhost:3000/rates/csv-search)
3. ✅ **Test admin interface** (http://localhost:3000/admin/csv-rates)
4. 📊 **Run load tests** (k6 scripts available)
5. 📝 **Update API documentation** (Swagger)
6. 🚀 **Deploy to staging** (Docker Compose)

## Known Limitations

- CSV files are static (no real-time updates from carriers)
- Test Maritime Express is fictional (for testing only)
- No caching implemented yet (planned: Redis 15min TTL)
- No audit logging for CSV uploads (planned)

## Support

If you encounter issues:

1. Check [MANUAL_TEST_INSTRUCTIONS.md](MANUAL_TEST_INSTRUCTIONS.md) for troubleshooting
2. Verify infrastructure is running: `docker ps`
3. Check API logs: `npm run dev` output
4. Verify migration ran: `npm run migration:run`

## Summary

🎯 **Status:** Ready for testing
📊 **Coverage:** 126 CSV rates across 5 companies
🧪 **Test Scripts:** 3 automated + 1 manual guide
⭐ **Test Data:** Fictional carrier with competitive pricing
✅ **Endpoints:** 8 API endpoints (3 public + 5 admin)

**Everything is implemented and ready to test!** 🚀

You can now:
1. Start the API server
2. Run the automated test scripts
3. Verify the comparator shows multiple companies
4. Confirm Test Maritime Express appears with cheaper rates
