   * form. So this method finds the form, verifies that it has input fields and
   * a submit button matching the inputs to this method, and then calls
   * WebTestBase::drupalGet() to simulate the form submission to the 'action'
   * URL of the form (if set, or the current URL if not).
   *
   * See WebTestBase::drupalPostForm() for more detailed documentation of the
   * function parameters.
   *
   * @param string $path
   *   Location of the form to be submitted: either a Drupal path, absolute
   *   path, or NULL to use the current page.
   * @param array $edit
   *   Form field data to submit. Unlike drupalPostForm(), this does not support
   *   file uploads.
   * @param string $submit
   *   Value of the submit button to submit clicking. Unlike drupalPostForm(),
   *   this does not support AJAX.
   * @param string $form_html_id
   *   (optional) HTML ID of the form, to disambiguate.
