How to test Zend framework2 form which implements CSRF element? - zend-framework

Question

I have created the login form using Zend/Form and it contains input elements as well as CSRF element.
<!-- sample login.phtml code snippet -->
<form method="post" action="/xyz">
<?php
echo $this->formelement($form->get('email'));
echo $this->formelement($form->get('password'));
echo $this->formelement($form->get('csrf'));
echo $this->formelement($form->get('submit'));
?>
</form>
The following testcase fails because of the validation against CSRF element.
public function testLogin()
{
//code goes here
$params = array('email' => 'example#test.com', 'password' => 'example#test.com');
$this->dispatch($url, $method, $params);
//if the given username and password is correct the login page redirected to default home page
$this->assertResponseStatusCode(302);
}
In the above testcase i set the email and password values but i don't know how to set CSRF element. How could i test the form which implements CSRF element?

Answer 1

This can easily be achieved with the following:
$form = new LoginForm();
$csrf = $form->get('csrf')->getValue();
$params = array('email' => 'example#test.com',
'password' => 'example#test.com',
'csrf' => $csrf
);
Unless your form needs the form manager when you are going to have to use that rather than just instantiating the class but that's pretty easy to do in a unit test as well.
UPDATE:
Another method that works:
$form = new LoginForm();
$form->prepare();
$params = new \Zend\Stdlib\Parameters(
array(
'csrf' => $_SESSION['Zend_Validator_Csrf_salt_csrf']['hash'],
'yourotherparams' => 'thingsandstuff'
);
$this->dispatch($url, $method, $params);
