SymfonyでFormTypeのunittestする場合の雛形 (getExtensionsで設定しないと、Validaterが読み込まれず、repeatedフォームを使っているとエラーになる)

symfony-formtype-phpunit.php

<?php
use Symfony\Component\Form\Test\TypeTestCase;
use Symfony\Component\Validator\Validation;
use Symfony\Component\Form\Extension\Validator\ValidatorExtension;

class PasswordFormType extends TypeTestCase
{
  protected function getExtensions()
  {
    return [new ValidatorExtension(Validation::createValidator())];
  }

  public function testPasswordLengthValid()
  {
    $formData = [
      "userID" => "lugecy",
      "password" => "passwd",
      "newPassword" => [
        // "first" => "pass",
        // "second" => "pass",
        "first" => "p0ssw0rd",
        "second" => "p0ssw0rd",
      ],
    ];
    $type = new App\PasswordFormType();
    $form = $this->factory->create($type);
    $form->submit($formData);
    // Something Code...
  }
}
