How does Joomla direct the controller method when submitting a form?

In the case where the form action is set to something like:

action="<?php echo JRoute::_('index.php?option=com_test&layout=edit&id='.(int) $this->item->id); ?>"

and the form also contains hidden input:

<input type="hidden" name="task" value="testctrl.save" />

How does Joomla route to the controller method?

I would understand if this task was in a form action, but I don’t see how he selects a task from hidden input in order to route the corresponding method in the controller method testctrl

It is not that difficult. Your directory com_mycomhas a file named mycom.php. It has a few lines that look like this:

$controller = JControllerLegacy::getInstance('Contact');
$controller->execute(JFactory::getApplication()->input->get('task'));
$controller->redirect();

See an example here: https://github.com/joomla/joomla-cms/blob/staging/components/com_contact/contact.php#L15

public function execute($task)
