Error Unit test symfony

Question

When I try to execute this unit test I have a problem so this is my function testErrors
.

    public function testErrors(){

    $client = static::createClient();

    $crawler = $client->request('GET', '/add');
    $form = $crawler->selectButton('save')->form(array(
    'user[firstName]'      => 'test1',
    'user[lastName]'       => 'test',
    'user[email]'          => '[email protected]',
    ));
    $crawler = $client->submit($form);

    //  3 errors
    $this->assertTrue($crawler->filter('.error_list')->count() == 3);
    // Error firstName field
    $this->assertTrue($crawler->filter('#firstName')->siblings()->first()->filter('.error_list')->count() == 1);
    // Error lasName field
    $this->assertTrue($crawler->filter('#lastName')->siblings()->first()->filter('.error_list')->count() == 1);
    // Error email field
    $this->assertTrue($crawler->filter('#email')->siblings()->first()->filter('.error_list')->count() == 1);

}

I have this problem

InvalidArgumentException: The current node list is empty .

this is my Controller

   /**
 * @Route("/add", name="addPage")
 */
public function AddAction(Request $request)
{

    $user = new User();

    $form = $this->createFormBuilder($user)
        ->add('email', TextType::class)
        ->add('firstName', TextType::class)
        ->add('lastName', TextType::class)
        ->add('save', SubmitType::class, array('label' => 'Add'))
        ->getForm();


    $form->handleRequest($request);

    if ($form->isSubmitted() && $form->isValid()) {


    $firstName = $form['firstName']->getData();
    $lastName = $form['lastName']->getData();
    $email = $form['email']->getData();
    $user->setFirstName($firstName);
    $user->setLastName($lastName);
    $user->setEmail($email);
    $em = $this->getDoctrine()->getManager();
    $em->persist($user);
    $em->flush();
    $this->addFlash('notice','user added' );
    return $this->redirectToRoute('listPage');
    }

and why you expect that the form get 3 validation error when don't have any constraint? — Matteo

Error in this line "" )); "" so in this statement $form = $crawler->selectButton('save')->form(array( 'user[firstName]' => 'test1', 'user[lastName]' => 'test', 'user[email]' => '[email protected]', )); — tr.am

before accessing the crawler, check that the request went fine with something like $this->assertTrue($client->getResponse()->isSuccessful()); after client->request — Matteo

I think it's your selectButton('save') what gives you the error. Try it with your button label Add instead of save

On which line? let's try separating the statements to track down your error to something like this: ``` $button = $crawler->selectButton('Add'); $form = $button->form(); $form->get('form[firstName]')->setValue('test1'); $form->get('form[lastName]')->setValue('test'); $form->get('form[email]')->setValue('[email protected]'); ``` Also I'm using 'form' as the fieldnames selector because for me that's how it's rendering the form.
