Form builder for testing \Drupal\Core\Form\FormValidatorInterface::validateForm().
Serves for testing form processing and alterations by form validation handlers, especially for the case of a validation error:
- $form_state->setValueForElement() should be able to alter submitted values in $form_state->getValues() without affecting the form element.
- #element_validate handlers should be able to alter the $element in the form structure and the alterations should be contained in the rebuilt form.
- #validate handlers should be able to alter the $form and the alterations should be contained in the rebuilt form.
