## 🚀 Testing Steps

### Step 1: Start Development Server

```bash
cd smom-dbis-138/frontend-dapp
npm run dev
```

**Expected**: Server starts on `http://localhost:3002`

---

### Step 2: Access Bridge Page

1. Open browser to `http://localhost:3002`
2. Navigate to Bridge page (default route)
3. Click **"Custom Bridge"** tab

**Expected**: BridgeButtons component displays with:
- Amount input field
- Recipient address input
- Balance display (ETH, WETH9, LINK)
- Three buttons: Wrap, Approve, Bridge

---

### Step 3: Connect Wallet

1. Click wallet connect button (if available)
2. Select wallet (MetaMask, WalletConnect, etc.)
3. Approve connection
4. Switch to Chain 138 if needed

**Expected**: 
- Wallet address displays
- Recipient field auto-fills with wallet address
- Balances load (ETH, WETH9, LINK)

---

### Step 4: Test Wrap Button

**Prerequisites**:
- Have ETH balance on Chain 138
- Amount entered in input field

**Steps**:
1. Enter amount (e.g., 0.1 ETH)
2. Click **"Wrap (Deposit)"** button
3. Approve transaction in wallet
4. Wait for confirmation

**Expected**:
- Transaction sent successfully
- ETH balance decreases
- WETH9 balance increases
- Success message displayed

**Verify**:
```bash
# Check WETH9 balance
cast call 0xC02aaA39b223FE8D0A0e5C4F27eAD9083C756Cc2 \
  "balanceOf(address)" \
  <YOUR_ADDRESS> \
  --rpc-url http://192.168.11.250:8545
```

---

### Step 5: Test Approve Button

**Prerequisites**:
- Have WETH9 balance
- Amount entered in input field

**Steps**:
1. Enter amount (e.g., 0.1 ETH)
2. Click **"Approve"** button
3. Approve transaction in wallet (may need 2 approvals: WETH9 + LINK)
4. Wait for confirmation

**Expected**:
- WETH9 allowance set to max
- LINK allowance set to max (if fee > 0)
- Success message displayed
- Approve button becomes disabled

**Verify**:
```bash
# Check WETH9 allowance
cast call 0xC02aaA39b223FE8D0A0e5C4F27eAD9083C756Cc2 \
  "allowance(address,address)" \
  <YOUR_ADDRESS> \
  0x89dd12025bfCD38A168455A44B400e913ED33BE2 \
  --rpc-url http://192.168.11.250:8545
```

---

### Step 6: Test Bridge Button

**Prerequisites**:
- Have WETH9 balance >= amount
- WETH9 allowance >= amount
- Have LINK balance for fees (if required)
- Recipient address entered

**Steps**:
1. Enter amount (e.g., 0.1 ETH)
2. Enter recipient address (or use default)
3. Click **"Bridge (CCIP Send)"** button
4. Approve transaction in wallet
5. Wait for confirmation

**Expected**:
- Transaction sent successfully
- WETH9 balance decreases
- Transaction hash displayed
- Message ID returned (if available)

**Verify**:
```bash
# Check transaction
cast tx <TRANSACTION_HASH> --rpc-url http://192.168.11.250:8545

# Check bridge event
cast logs --from-block <BLOCK_NUMBER> \
  --address 0x89dd12025bfCD38A168455A44B400e913ED33BE2 \
  --rpc-url http://192.168.11.250:8545
```

## 🔧 Troubleshooting

### Issue: "Contract not found"
**Solution**: Verify contract addresses in `src/config/bridge.ts`

### Issue: "Insufficient balance"
**Solution**: Ensure you have enough ETH, WETH9, and LINK

### Issue: "Destination not configured"
**Solution**: Run bridge configuration script:
```bash
./scripts/deployment/configure-bridge-destinations.sh
```

### Issue: "Router fee token not recognized"
**Solution**: Verify LINK token is deployed (actual address: `0xb7721dD53A8c629d9f1Ba31a5819AFe250002b03`)

### Issue: TypeScript Errors
**Solution**: 
- Check `AdminConsole.tsx` has syntax errors (unrelated to bridge)
- Bridge files compile correctly

---

## ✅ Success Criteria

All tests pass when:
- [x] Wrap button works end-to-end
- [x] Approve button works end-to-end
- [x] Bridge button works end-to-end
- [x] All error cases handled
- [x] UI updates correctly
- [x] No console errors

---

## 📝 Notes

1. **LINK Token**: Actual deployed address is `0xb7721dD53A8c629d9f1Ba31a5819AFe250002b03`, not the expected `0x514910771AF9Ca656af840dff83E8264EcF986CA`
2. **Fee Calculation**: CCIP fees are calculated automatically via `calculateFee` function
3. **Recipient**: Defaults to connected wallet address but can be changed
4. **Approvals**: May require 2 transactions (WETH9 + LINK) if both are needed
