silent-failure-review

To find swallowed errors during a code review, trace all error handlers, try-catch blocks, and fallback logic to verify proper error propagation and logging. This process flags unlogged or swallowed errors in line with project conventions.

A silent failure in error handling paths occurs when exceptions or unhandled promises are caught but not logged or propagated, making errors invisible. Auditing exposes these paths to ensure they are visible, logged, and actionable.

Auditing try-catch blocks for unlogged exceptions involves a phase-based methodology of context research, comparative analysis, and exhaustive audit. This verifies logs and user-facing messages while flagging swallowed errors.

Yes, the silent failure audit applies to ad-hoc checks of software projects. It traces error callbacks and fallback logic, verifying error propagation and flagging swallowed errors across the entire codebase.

The best way to prevent silent failures in pull requests is to perform exhaustive error-handler discovery and assessment on changed code paths. This ensures every error path is visible, logged, and actionable before merging.

Unhandled promises are considered silent failures because they bypass error callbacks without logging or propagating the exception. Tracing these promises during an audit ensures proper error handling and prevents degraded user trust.
