Laravel container doesn't resolve Test methods dependencies

I have a test suit for a CLI program created in App\Commands namespace. The problem I have is that it seems laravel container doesn't resolve test method dependencies nor laravel helpers, ... . I'm on Windows 10.

PHP code :

<?php

use Illuminate\Foundation\Testing\WithoutMiddleware;
use Illuminate\Foundation\Testing\DatabaseMigrations;
use Illuminate\Foundation\Testing\DatabaseTransactions;

use ACME\SomeClass;

class CLICommandTest extends TestCase
{
    use DatabaseTransactions;

    protected $key = '';
    protected $someClass = null;

    public function __construct(SomeClass $someClass)
    {
        parent::__construct();

        $this->someClass = $someClass;
        $this->key = config('someconfig')['key'];
    }

    /*
     * test handle method
     */
    public function testHandle()
    {
        //assertions
    }

}

I've created & included the service provider for this :

<?php

use ACME\someClass;

$this->app->bind('ACME\SomeClass', function($app){
    return new SomeClass($value);
});

when I run phpunit from either PATH or vendor/bin this error comes up :

PHP Fatal error:  Uncaught TypeError: Argument 1 passed to CLICommandTest::__construct() must be an instance of ACME\someClass, none given, called in phar://C:/PHPUnit/phpunit/phpunit/Framework/TestSuite.php on line 475 and defined in C:\path\tests\CLICommandTest.php:16
