Queues and Horizon

Run workers safely, verify execution, and test job behavior.

Commands

Start worker

sail artisan queue:work --queue=high,default --tries=3 --backoff=5 # or: php artisan queue:work --queue=high,default --tries=3 --backoff=5

Horizon (if installed)

sail artisan horizon # or: php artisan horizon

Failed jobs

sail artisan queue:failed # or: php artisan queue:failed sail artisan queue:retry all # or: php artisan queue:retry all

Patterns

• Use named queues for prioritization; keep defaults sane

• Add actionable Log::warning /::error with context in jobs

• Idempotency: make jobs safe to retry

• Emit metrics where possible; observe in Horizon or your APM

Testing Jobs

• Use Bus::fake() to assert dispatching in unit tests

• Use integration tests to verify side-effects (DB/IO)
