Unable to locate factory with name [default] [App\User].

What does your UserFactory.phplook like?

Can you show the code for the factory?

use App\Models\User;


.
.
.


$factory->define(User::class, function (Faker $faker) {

@tray2 @mushood

I've removed the actual attributes to just simplify.

<?php

/** @var \Illuminate\Database\Eloquent\Factory $factory */

use App\User;
use Faker\Generator as Faker;
use Illuminate\Support\Str;

$factory->define(User::class, function (Faker $faker)
{
    return [
    ...
    ];
});

Could you try this?

Where you are calling the factory

use App\User;

.
.
.
.
factory(User::class)->create();

@mushood Inside my UserTest file.

    use App\User;

    public function my_user_test()
    {
        $user = factory(User::class)->create();
    }

Same error with code above. InvalidArgumentException : Unable to locate factory with name [default] [App\User].

Very weird.

Don't see anything wrong

Maybe try clearing cache

php artisan cache:clear

composer dump-autoload

Is the UserFactory.php placed in the correct directory?

database/factories/UserFactory.php

Have you seen this thread? If not might be worth a read.

Ok I solved the issue. For whatever reason, the UserTest had the use statement of; use PHPUnit\Framework\TestCase; Where as it should've been; use Tests\TestCase;

I have no clue why this was like this and I do not recall changing it at all. Not sure if Laravel comes with this by default?

that's the intended way now in Laravel, take a look here:

https://github.com/laravel/framework/commit/e30a0c979d98f2f1f7b6c565e4002734237a280b

it basically says that if you need to use factory you should create a Feature test and not a Unit test.
