Test code or tested code did not (only) close its own output buffers

[PankovAlxndr]

PHP 8.2
Laravel 10
Pest 2

test('create new user', function () {
    Storage::fake('avatars');
    $image = UploadedFile::fake()->image('avatar.png');

    expect(1)->toBe(1);
});

Output:
`./vendor/bin/pest --filter UserCreateTest

WARN Tests\Feature\Users\UserCreateTest
! create new user → Test code or tested code did not (only) close its own output buffers `

Why?

[k-pognerybko]

В UploadedFile используется метод generateImage из /vendor/laravel/framework/src/Illuminate/Http/Testing/FileFactory.php
Для его корректной работы нужен модуль GD (для imagecreatetruecolor($width, $height);)
После установки зависимости проблема должна исчезнуть
