CarbonSetTestNowToTravelToRector

Use the $this->travelTo() method in Laravel's TestCase class instead of the Carbon::setTestNow() method.

 use Illuminate\Support\Carbon;
 use Illuminate\Foundation\Testing\TestCase;

 class SomeTest extends TestCase
 {
     public function test()
     {
-        Carbon::setTestNow('2024-08-11');
+        $this->travelTo('2024-08-11');
     }
 }

Configure your rector.php:

<?php

use RectorLaravel\Rector\StaticCall\CarbonSetTestNowToTravelToRector;
use Rector\Config\RectorConfig;

return RectorConfig::configure()
    ->withRules([
        CarbonSetTestNowToTravelToRector::class,
    ]);
