## Testing Recommendations
|
|
|
|
Before going live, verify:
|
|
|
|
1. **Payment Flow End-to-End:**
|
|
```bash
|
|
# Test webhook with valid signature
|
|
# Test webhook with invalid signature (should return 401)
|
|
```
|
|
|
|
2. **Session Persistence:**
|
|
```bash
|
|
# Login, restart server, verify session still valid
|
|
```
|
|
|
|
3. **SQLCipher Validation:**
|
|
```bash
|
|
# Test with valid hex key - should work
|
|
# Test with invalid key - should fail with clear error
|
|
```
|
|
