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)
