      'Drupal\Tests\block\Functional\BlockTest' => [
        'name' => 'Drupal\Tests\block\Functional\BlockTest',
        'description' => 'Tests block UI CRUD functionality.',
        'group' => 'block',
        'groups' => ['block', 'group2', 'group3'],
      ],
    ];

@todo Remove singular grouping; retain list of groups in 'group' key.

Parameters

string $extension: (optional) The name of an extension to limit discovery to; e.g., 'node'.

string[] $types: (optional) An array of included test types.

string|null $directory: (optional) Limit discovered tests to a specific directory.
