4. 11.x core/lib/Drupal/Core/Test/TestDiscovery.php \Drupal\Core\Test\TestDiscovery::getTestClasses()

Discovers all available tests in all extensions.

    $groups['block'] => array(
      'Drupal\Tests\block\Functional\BlockTest' => array(
        '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: An array of included test types.

Return value

array An array of tests keyed by the group name. If a test is annotated to belong to multiple groups, it will appear under all group keys it belongs to.
