错误单元测试 symfony

Question

当我尝试执行这个单元测试时 我有个问题 所以这是我的函数 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]'          => 'test@gmail.com',
    ));
    $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);

}

我有这个问题

InvalidArgumentException: 当前节点列表为空。

这是我的控制器

   /**
 * @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');
    }

我认为是您的selectButton('save') 给您带来了错误。尝试使用您的按钮标签 Add 而不是 save
