Error while writing the test about laravel-data

[trianity]

I ran into a similar problem.
The spatie/laravel-data package was used in my own package with Pest 2.x test framework.

The error message is: BindingResolutionException Unresolvable dependency resolving [Parameter #0 [ array $config ]] in class Spatie\LaravelData\Support\DataConfig

My PackageTestCase was used as follow:

use Orchestra\Testbench\TestCase;

class PackageTestCase extends TestCase
{
}

Correcting the PackageTestCase the issue was resolved:

use Orchestra\Testbench\TestCase;
use MyPackage\Providers\PackageServiceProvider;
use Spatie\LaravelData\LaravelDataServiceProvider;

class PackageTestCase extends TestCase
{
    protected function setUp(): void
    {
        parent::setUp();
        // additional setup
        config()->set('app.key', '6rE9Nz59bGRbeMATftriyQjrpF7DcOQm');
    }
    
    protected function getPackageProviders($app): array
    {
        return [
            LaravelDataServiceProvider::class,
            PackageServiceProvider::class,
        ];
    }
}

@inguldima You need to use feature tests, the service provider isn't bound because of the different TestCase class used in unit tests.

//use PHPUnit\Framework\TestCase;
use Tests\TestCase;

Somehow the LaravelDtaaServiceProvider isn't ran: https://github.com/spatie/laravel-data/blob/main/src/LaravelDataServiceProvider.php

Make sure it is otherwise the required bindings are not set up.
