Failures here indicate: +- Registry conflicts (metric already registered) +- Serialization errors (corrupt internal state) +- UTF-8 conversion errors (corrupt metric data) + +All of these are **unrecoverable test setup errors** that should halt execution immediately with clear diagnostic information. + +### Documented Invariants +Each `expect()` call includes a descriptive message that: +1. Identifies what failed +2. Explains why it failed (root cause category) +3. Helps developers diagnose the issue quickly + +## Acceptance Criteria ✓ + +- [x] All 15 avoidable `unwrap()` calls removed +- [x] Each `expect()` includes justified, descriptive error context +- [x] Error messages preserve observability context +- [x] No diagnostics errors found in the file +- [x] Changes maintain test isolation (each test uses independent registries) + +## Testing + +File passes static analysis with no diagnostics errors. The use of `expect()` is justified because: +1. These are test-only helpers, not production code +2. Failures indicate test setup issues, not runtime errors +3. Each panic is well-documented with clear error messages +4. Tests cannot meaningfully continue if metric registration fails + +## Notes + +- No production code affected (test file only) +- Test structure unchanged - still using isolated registries +- All error messages follow consistent format +- Zero remaining `unwrap()` calls in the file diff --git a/tests/alerting_integration.rs b/tests/alerting_integration.rs index d9625533..aec241ae 100644 --- a/tests/alerting_integration.rs +++ b/tests/alerting_integration.rs @@ -31,7 +31,7 @@ mod alerting_metrics_tests { &["method", "route", "status_code"], r ) - .unwrap() + .expect("Failed to register aframp_http_requests_total metric - this is a test setup error indicating registry conflict") } fn make_cngn_transactions_total(r: &Registry) -> prometheus::CounterVec { @@ -41,7 +41,7 @@ mod alerting_metrics_tests { &["tx_type", "status"], r ) - .unwrap() + .expect("Failed to register aframp_cngn_transactions_total metric - this is a test setup error indicating registry conflict") } fn make_stellar_submissions_total(r: &Registry) -> prometheus::CounterVec { @@ -51,7 +51,7 @@ mod alerting_metrics_tests { &["status"], r ) - .unwrap() + .expect("Failed to register aframp_stellar_tx_submissions_total metric - this is a test setup error indicating registry conflict") } fn make_worker_errors_total(r: &Registry) -> prometheus::CounterVec { @@ -61,7 +61,7 @@ mod alerting_metrics_tests { &["worker", "error_type"], r ) - .unwrap() + .expect("Failed to register aframp_worker_errors_total metric - this is a test setup error indicating registry conflict") } fn make_worker_cycles_total(r: &Registry) -> prometheus::CounterVec { @@ -71,7 +71,7 @@ mod alerting_metrics_tests { &["worker"], r ) - .unwrap() + .expect("Failed to register aframp_worker_cycles_total metric - this is a test setup error indicating registry conflict") } fn make_db_errors_total(r: &Registry) -> prometheus::CounterVec { @@ -81,7 +81,7 @@ mod alerting_metrics_tests { &["error_type"], r ) - .unwrap() + .expect("Failed to register aframp_db_errors_total metric - this is a test setup error indicating registry conflict") } fn make_payment_provider_failures_total(r: &Registry) -> prometheus::CounterVec { @@ -91,7 +91,7 @@ mod alerting_metrics_tests { &["provider", "failure_reason"], r ) - .unwrap() + .expect("Failed to register aframp_payment_provider_failures_total metric - this is a test setup error indicating registry conflict") } fn make_exchange_rate_last_updated(r: &Registry) -> prometheus::GaugeVec { @@ -101,7 +101,7 @@ mod alerting_metrics_tests { &["currency_pair"], r ) - .unwrap() + .expect("Failed to register aframp_exchange_rate_last_updated_timestamp_seconds metric - this is a test setup error indicating registry conflict") } fn make_worker_last_cycle_timestamp(r: &Registry) -> prometheus::GaugeVec { @@ -111,7 +111,7 @@ mod alerting_metrics_tests { &["worker"], r ) - .unwrap() + .expect("Failed to register aframp_worker_last_cycle_timestamp_seconds metric - this is a test setup error indicating registry conflict") } fn make_pending_transactions_stale(r: &Registry) -> prometheus::GaugeVec { @@ -121,7 +121,7 @@ mod alerting_metrics_tests { &["tx_type"], r ) - .unwrap() + .expect("Failed to register aframp_pending_transactions_stale_total metric - this is a test setup error indicating registry conflict") } fn make_rate_limit_breaches_total(r: &Registry) -> prometheus::CounterVec { @@ -131,7 +131,7 @@ mod alerting_metrics_tests { &["endpoint"], r ) - .unwrap() + .expect("Failed to register aframp_rate_limit_breaches_total metric - this is a test setup error indicating registry conflict") } fn make_cache_hits_total(r: &Registry) -> prometheus::CounterVec { @@ -141,7 +141,7 @@ mod alerting_metrics_tests { &["key_prefix"], r ) - .unwrap() + .expect("Failed to register aframp_cache_hits_total metric - this is a test setup error indicating registry conflict") } fn make_cache_misses_total(r: &Registry) -> prometheus::CounterVec { @@ -151,14 +151,17 @@ mod alerting_metrics_tests { &["key_prefix"], r ) - .unwrap() + .expect("Failed to register aframp_cache_misses_total metric - this is a test setup error indicating registry conflict") } fn render(r: &Registry) -> String { let encoder = TextEncoder::new();
