FilamentPHP Testing Skill

Overview

This skill generates comprehensive Pest tests for FilamentPHP v4 components following official testing documentation patterns.

Documentation Reference

CRITICAL: Before generating tests, read:

    $this->actingAs(\App\Models\User::factory()->create([
        'is_admin' => true,
    ]));
}

}
