Middleware Edge Cases

Test middleware edge cases by enumerating protected and public routes, simulating unauthenticated and authenticated access requests, and verifying correct redirect behavior or denial to produce an audit checklist.

Redirect loops occur when middleware rules continuously bounce requests. Verify redirect loop absence by repeating requests against your route map and validating response stability across local and staging environments.

Check static asset and API route interference by running middleware edge case checks against your known route map, verifying static assets and API routes remain unaffected during middleware logic changes.

Testing auth redirects requires a running local dev server. Execute middleware edge case checks against your route map to simulate auth states and produce a passing or failing audit checklist.

The best way to prevent routing regressions is applying a structured approach to test middleware edge cases, verifying authentication gating, redirect behavior, and consistent access control across routes.
