CLI-Test not working - Githubissues

I am just trying to start with laravel-vfs. I worte some test to use laravel vfs storage instead of sFTP-storage. The provider is not able to create a directory.

Steps:

composer require mmieluch/laravel-vfs-provider
Register new service provider in config/app.php
Update config/filesystems.php file
Started a simple test.

Environment:

Windows 10
PHPStorm 2016.1
Laravel Framework version 5.2.39
PHP 7.0.0 (cli) (built: Dec 3 2015 09:31:42) ( ZTS )

Error message:

mkdir(): Invalid argument
 \vendor\league\flysystem\src\Adapter\Local.php:357
 \vendor\league\flysystem\src\Filesystem.php:259
 \vendor\laravel\framework\src\Illuminate\Filesystem\FilesystemAdapter.php:304
 \tests\RenderTest.php:8

Errornous line debugged details:

mkdir('phpvfs577a380d4a238:\\test', 0755, true)

Test function:

class RenderTest extends TestCase
{
    public function testFirst()
    {
        $storage = Storage::disk('virtual');
        $storage->makeDirectory('test');
        print_r($storage->allFiles());
    }
}

filesystems.php:

    'disks' => [

        'local' => [
            'driver' => 'local',
            'root' => storage_path('app'),
        ],

        'virtual' => [
            'driver' => 'vfs',
        ],
