Testing

Framework

Pest PHP. Never use PHPUnit test classes directly — always Pest syntax.

Test structure

Conventions

• Use RefreshDatabase trait on Feature tests
• Factory-first: all test data via Eloquent factories — never raw DB inserts
• Mock external APIs (Fuel Finder, Vonage, OneSignal, FRED) — never hit live APIs in tests
• Use Http::fake() for all outbound HTTP in tests
• Stripe: use Cashier's built-in test helpers, never hit Stripe API in tests

What to test

• AlertScoringService: all signal combinations, confidence thresholds, no_signal cases
• NotificationDispatchService: correct channels returned per tier
• SubscriptionService: tier detection, SMS limit counting
• Livewire components: use Livewire::test() for interaction testing
• Stripe webhooks: test customer.subscription.deleted downgrades user correctly

Running tests

php artisan test              # Full suite
php artisan test --filter=Scoring  # Single test class
php artisan test --parallel   # Parallel (faster)
