Description: 

@requires externalCommand is not a supported syntax in PHPUnit 10, and its parser no longer processes it. Drupal core previously used this to ensure Composer was available in build tests:

  * @requires externalCommand composer

It has been replaced with a new trait that skips a test if Composer is not available. To use it simply add the trait to your test class:

use Drupal\TestTools\Extension\RequiresComposerTrait;

class MyTest extends TestCase {
  use RequiresComposerTrait;

...
}

No further configuration is required.
