-**Unexpected Errors**: -- Serialization failures -- Unexpected state conditions -- Returns: "Internal server error: {details}" -- Logged for debugging - -### Error Handling in Batch Operations - -Batch replays implement fail-safe error handling: - -1. **Individual Failure Isolation**: One failed replay doesn't abort the batch -2. **Detailed Error Reporting**: Each failed replay includes specific error message -3. **Summary Statistics**: Response includes total, successful, and failed counts -4. **Partial Success Support**: Batch can succeed partially (some pass, some fail) - -Example batch response with mixed results: -```json -{ - "total": 3, - "successful": 2, - "failed": 1, - "results": [ - { - "transaction_id": "uuid-1", - "success": true, - "message": "Webhook replayed successfully", - "dry_run": false, - "replayed_at": "2026-02-23T11:00:00Z" - }, - { - "transaction_id": "uuid-2", - "success": false, - "message": "Transaction uuid-2 not found", - "dry_run": false, - "replayed_at": null -

-All errors are logged with appropriate severity levels: - -**ERROR Level**: -- Database connection failures -- Unexpected processing errors -- Authentication/authorization failures - -**WARN Level**: -- Transaction not found (may be expected) -- Replay of completed transaction attempted -- Batch size limit exceeded - -**INFO Level**: -- Successful replay operations -- Dry-run executions -- Query operations - -Each log entry includes: -- Transaction ID (when applicable) -- Operator identity -- Error message and context -- Timestamp -- Request parameters - -### Retry and Recovery - -**No Automatic Retries**: Replay operations do not automatically retry on failure. This is intentional: -- Operators should investigate failures before retrying -- Prevents cascading failures -- Allows for manual intervention and debugging - -**Manual Retry**: Operators can manually retry failed replays: -- Review error message in replay history -- Address underlying issue -- Submit new replay request - -**Idempotency Protection**: Even with manual retries, idempotency keys prevent duplicate processing of successfully completed webhooks. - -## Testing Strategy - -The webhook replay system requires comprehensive testing across multiple dimensions to ensure correctness, reliability, and safety. We employ a dual testing approach combining property-based testing for universal correctness guarantees with unit testing for specific examples and edge cases. - -### Testing Approach - -**Property-Based Testing**: Validates universal properties across all inputs -- Generates random test data (transaction IDs, payloads, filters) -- Executes properties 100+ times per test -- Catches edge cases that manual testing might miss -- Provides strong correctness guarantees - -**Unit Testing**: Validates specific examples and integration points -- Tests concrete scenarios with known inputs/outputs -- Validates error conditions with specific error messages -- Tests integration between components -- Provides regression protection - -### Property-Based Testing Configuration - -**Framework**: Use `proptest` crate for Rust property-based testing - -**Configuration**: -```rust -proptest! { - #![proptest_config(ProptestConfig::with_cases(100))] - // Test cases here -} -``` - -**Test Tagging**: Each property test must reference its design property: -```rust -// Feature: webhook-replay-admin-interface, Property 1: Complete Webhook Storage -#[test] -fn prop_complete_webhook_storage() { - // Test implementation -} -``` - -### Property Test Implementation Examples - -**Property 2: Status Filter Correctness** -```rust -// Feature: webhook-replay-admin-interface, Property 2: Status Filter Correctness -#[proptest] -fn prop_status_filter_correctness( - #[strategy(webhook_status_strategy())] status: String, - #[strategy(vec(transaction_strategy(), 0..50))] transactions: Vec -) { - // Setup: Insert transactions with various statuses - // Execute: Query with status filter - // Assert: All returned transactions have matching status -} -``` - -**Property 14: Batch Summary Correctness** -```rust -// Feature: webhook-replay-admin-interface, Property 14: Batch Summary Correctness -#[proptest] -fn prop_batch_summary_correctness( - #[strategy(vec(any::(), 1..100))] transaction_ids: Vec -) { - // Setup: Create mix of valid and invalid transaction IDs - // Execute: Batch replay - // Assert: total == successful + failed - // Assert: total == transaction_ids.len() -} -``` - -**Property 17: Dry-Run State Preservation** -```rust -// Feature: webhook-replay-admin-interface, Property 17: Dry-Run State Preservation -#[proptest] -fn prop_dry_run_state_preservation( - #[strategy(transaction_strategy())] transaction: Transaction -) { - // Setup: Record initial database state - // Execute: Dry-run replay - // Assert: Database state unchanged (status, idempotency, etc.) -} -``` - -### Unit Test Coverage - -**Endpoint Existence Tests**: -- Verify `/admin/webhooks/failed` endpoint exists and responds -- Verify `/admin/webhooks/replay/:id` endpoint exists -- Verify `/admin/webhooks/replay/batch` endpoint exists - -**Specific Error Condition Tests**: -- Test 404 error for non-existent transaction ID -- Test 401 error for missing authentication -- Test 403 error for non-admin user -- Test 400 error for invalid UUID format -- Test 400 error for batch size > 1000 - -**Integration Tests**: -- Test complete replay flow: list failed → replay → verify status change -- Test dry-run doesn't affect database state -- Test batch replay with mixed success/failure -- Test audit logging integration -- Test replay history tracking - -**Serialization Tests**: -- Test ReplayResult JSON serialization -- Test BatchReplayResponse JSON serialization -- Test FailedWebhooksResponse JSON serialization - -### Test Data Generators - -**Transaction Generator**: -```rust -fn transaction_strategy() -> impl Strategy { - ( - stellar_account_strategy(), - amount_strategy(), - asset_code_strategy(), - option::of(any::()), // anchor_transaction_id - webhook_status_strategy(), - ).prop_map(|(account, amount, asset, anchor_id, status)| { - Transaction::new(account, amount, asset, anchor_id, - Some("deposit".to_string()), - Some(status), None, None, None) - }) -} -``` - -**Webhook Status Generator**: -```rust -fn webhook_status_strategy() -> impl Strategy { - prop_oneof![ - Just("pending".to_string()), - Just("completed".to_string()), - Just("failed".to_string()), - ] -} -``` - -**UUID Generator**: -```rust -fn uuid_strategy() -> impl Strategy { - any::<[u8;
