How do I add the "error" class when a form validation fails?

I’m working with Drupal 7.56 and I am using the Webform module to create a custom form.

I used hook_form_alter() in a custom module to add a validation test. 

function mymodule_form_alter(&$form, &$form_state, $form_id) {   if ($form_id=='webform_client_form_1') {     $form['#validate'][]='mymodule_form_validate';     return $form;   } }  function mymodule_form_validate($form, &$form_state) {   $aux = $form_state['values']['submitted']['aux'];   if ($aux != '') {     if( /* my test */ ) {       $text = t('Please check your input');       form_set_error('aux', $text);     }   } }

How can I add the error class when my test fails?
