*
* @param $path
* Location of the post form. Either a Drupal path or an absolute path or

* path to NULL and have it post to the last received page. Example:
*
* @code
* // First step in form.
* $edit = array(...);
* $this->drupalPost('some_url', $edit, t('Save'));
*
* // Second step in form.
* $edit = array(...);
* $this->drupalPost(NULL, $edit, t('Save'));
* @endcode
* @param $edit
* Field data in an associative array. Changes the current input fields
* (where possible) to the values indicated. A checkbox can be set to
* TRUE to be checked and FALSE to be unchecked. Note that when a form
* contains file upload fields, other fields cannot start with the '@'
* character.
*
* Multiple select fields can be set using name[] and setting each of the
* possible values. Example:
* @code
* $edit = array();
* $edit['name[]'] = array('value1', 'value2');
* @endcode
* @param $submit
* Value of the submit button whose click is to be emulated. For example,
* t('Save'). The processing of the request depends on this value. For
* example, a form may have one button with the value t('Save') and another
* button with the value t('Delete'), and execute different code depending
* on which one is clicked.
*
* This function can also be called to emulate an Ajax submission. In this
* case, this value needs to be an array with the following keys:
* - path: A path to submit the form values to for Ajax-specific processing,
* which is likely different than the $path parameter used for retrieving
* the initial form. Defaults to 'system/ajax'.
* - triggering_element: If the value for the 'path' key is 'system/ajax' or
* another generic Ajax processing path, this needs to be set to the name
* of the element. If the name doesn't identify the element uniquely, then
* this should instead be an array with a single key/value pair,
* corresponding to the element name and value. The callback for the
* generic Ajax processing path uses this to find the #ajax information
* for the element, including which specific callback to use for
* processing the request.
*
* This can also be set to NULL in order to emulate an Internet Explorer
* submission of a form with a single text field, and pressing ENTER in that
* textfield: under these conditions, no button information is added to the
* POST data.
* @param $options
* Options to be forwarded to url().
* @param $headers
* An array containing additional HTTP request headers, each formatted as
* "name: value".
* @param $form_html_id
* (optional) HTML ID of the form to be submitted. On some pages
* there are many identical forms, so just using the value of the submit
* button is not enough. For example: 'trigger-node-presave-assign-form'.
* Note that this is not the Drupal $form_id, but rather the HTML ID of the
* form, which is typically the same thing but with hyphens replacing the
* underscores.
* @param $extra_post
* (optional) A string of additional data to append to the POST submission.
* This can be used to add POST data for which there are no HTML fields, as
* is done by drupalPostAJAX(). This string is literally appended to the
* POST data, so it must already be urlencoded and contain a leading "&"
* (e.g., "&extra_var1=hello+world&extra_var2=you%26me").
