Requirements

• PHP 8.4+
• Laravel 13
• Pest 5 (PHPUnit 13) — the assertions ship as Pest expectations
• Orchestra Testbench 11 — installed as a dependency; only PackageTestCase and its concerns use it
• A reachable Postgres or MySQL only for the real-engine assertions, races and driver legs — everything else runs on in-memory SQLite
• Optional: ext-pcntl and ext-posix (suggested, not required) for Racer — without them Racer::available() is false and racing tests skip

Install it into require-dev only — the package ships nothing that runs in production. Its own suite runs with:

composer test
