Functional testing using User model in a Laravel 8 package

Question

I am coding a Laravel package, and I have written functional testing. For that, I need to seed users, using factories.

In my config, I have :

    'user' => [
        'table'       => 'users',
        'primary_key' => 'id',
        'foreign_key' => 'user_id',
        'model'       => App\Models\User::class,
    ],

But in my test package, App\Models\User is not defined, because it is only defined in main laravel project.

So, I tried to use use Illuminate\Foundation\Auth\User instead of App\Models\User in my tests, but I get a message :

InvalidArgumentException: Unable to locate factory for [Illuminate\Foundation\Auth\User].

Which I understand. But I cannot find a way to solve my issue a this point.

In my package's ServiceProvider, I have :

    $this->publishes([__DIR__ . '/../database/seeders' => $this->app->databasePath().'/seeders'], 'laravel-tournaments');
    $this->publishes([__DIR__.'/../database/factories' => $this->app->databasePath().'/factories'], 'laravel-tournaments');
    $this->publishes([__DIR__.'/../config/laravel-tournaments.php' => config_path('laravel-tournaments.php')], 'laravel-tournaments');

Any idea ?

I found an answer examinating Laravel Permission package.

For functional testing, inside test folder, they put a TestModels/ folder with a copy of User class.

<?php

namespace Spatie\Permission\Tests\TestModels;

use Spatie\Permission\Traits\HasRoles;

class User extends UserWithoutHasRoles
{
    use HasRoles;
}

With trait hasRoles :

<?php

namespace Spatie\Permission\Tests\TestModels;

use Illuminate\Auth\Authenticatable;
use Illuminate\Contracts\Auth\Access\Authorizable as AuthorizableContract;
use Illuminate\Contracts\Auth\Authenticatable as AuthenticatableContract;
use Illuminate\Database\Eloquent\Model;
use Illuminate\Foundation\Auth\Access\Authorizable;

class UserWithoutHasRoles extends Model implements AuthenticatableContract, AuthorizableContract
{
    use Authenticatable;
    use Authorizable;

    protected $fillable = ['email'];

    public $timestamps = false;

    protected $table = 'users';
}

All the models than depends on User should also be duplicated there
