Laravel Faker Unknown formatter

I have tried everything possible but I could not get to the bottom of what I am doing wrong. I am trying to load my database with dummy data but I keep get unknown formatter "description". Description is one of the variables I am using.

Below is my factory code and my seeder coder

use Faker\Generator as Faker;
use Analytics\Blockgrant;

$factory->define(Blockgrant::class, function (Faker $faker) {
    return [
        'description' => $faker->description,
        'value' => $faker->value
    ];
});

<?php

use Faker\Generator as Faker;
use Universityobfanalytics\Blockgrantcomponents;

$factory->define(Blockgrantcomponents::class, function (Faker $faker) {
    return [
        'blockgrants_id' => $faker->blockgrants_id,
        'description' => $faker->description,
        'percentage' => $faker->percentage,
        'value' => $faker->value
    ];
});

<?php

use Illuminate\Database\Seeder;
use Analytics\Blockgrant;
use Analytics\Blockgrantcomponents;

class BlockgrantSeeder extends Seeder
{
    /**
     * Run the database seeds.
     *
     * @return void
     */
    public function run()
    {
        factory(Blockgrant::class, 10)->create()->each(function ($blockgrant) {
            $blockgrant->blockgrantcomponents()->save(factory(Blockgrantcomponents::class)->create());

        });
    }
}

I am using a one to one hasOne and belongsTo relationship

Can somebody please assist by telling me what I am doing wrong.

You will face this issue when using Factories in PhpUnit DataProvider. As the DataProdiver is called before the test suite is properly bootstraped, the faker is not yet initialized. To get around this issue use the callbacks:

//...
public static function provideDifferentModelStates()
{
    return [
        'foo' => [
            fn() => MyModel::factory()->foo()->make(),
        ],
        'bar' => [
            fn() => MyModel::factory()->bar()->make(),
        ],
        'both' => [
            fn() => MyModel::factory()->foo()->bar()->make()
        ]
    ];
}

#[DataProvider('provideDifferentUpdates')]
public function testMyModelStates(callable $parameters)
{
    $model = $parameters();
    // your code and assertions
}
//...

You need to declare "description" like paragraph, that's all. I hope this information be useful:

        'description' => $faker->paragraph

In my case, I had forgotten to run the parent::setUp() function in the child class's setUp() function.

Solution 1 - if use tests

Check in test setUp, do you call parent::setUp().

protected function setUp(): void
{
    parent::setUp();
    $this->setUpBannedUsersList();
}

Solution 2 Try create and use new faker:

$faker = \Faker\Factory::create();

Example

class UserFactory extends Factory
{    
    protected $model = User::class;

    public function definition(): array
    {
        //Instead of using $this->faker use new created $faker

        $faker = \Faker\Factory::create();

        return [
            'name' => $faker->name,
            'email' => $faker->unique()->safeEmail,
            'password' => Hash::make($faker->password),
        ];
    }
}

You need to create your own TestCase class, which will use the CreatesApplication trait you created.
All this will look like this:

class TestCase extends BaseTestCase
{
    use CreatesApplication;
}

trait CreatesApplication
{
    public function createApplication(): Application
    {
        $app = require __DIR__.'/../bootstrap/app.php';

        $app->make(Kernel::class)->bootstrap();

        return $app;
    }
}

I am using Pest and was getting the same error when trying to write unit tests in my project, my solution:

In the file tests/Pest.php, I had a line like this:

uses(Tests\TestCase::class)->in('Feature');

I changed it to this and it worked

uses(Tests\TestCase::class)->in('Feature', 'Unit');

In the classTest/TestCase, remember to call parent::setup() in the constructor, like this:

 protected function setUp(): void
{
    try {
        parent::setUp();
    } catch (QueryException $e) {
        file_put_contents(
            getcwd() . '/testing_env_log',
            json_encode([
                'db' => Config::get('database'),
                'env' => $_ENV,
                'app' => Config::get('app'),
            ], JSON_THROW_ON_ERROR)
        );

        throw $e;
    }
    Event::fake();
}

It can be because you are using PHPUnit\Framework\TestCase instead of Tests\TestCase in your test.
