Invalid CSRF token: Behat test for registration form on Symfony 2

Question

I'm working on a test suite with behat on a Symfony 2.7 application.

It's a very simple piece of code to test the registration form, but it fails because of the CSRF token.

What's the problem with my configuration?

How can I avoid this problem?

This is my behat.yml:

default:
  suites:
    frontend_test_suite:
        type: symfony_bundle
        bundle: 'AppBundle'
  extensions:
    Behat\Symfony2Extension: ~
    Behat\MinkExtension:
      base_url: http://application.local/app_test.php
      browser_name: chrome
      sessions:
        default:
          symfony2: ~
      show_auto: true
      show_cmd: echo %s

And this is my FeatureContext's class:

    <?php

    namespace MobileLeaves\Bundles\AppBundle\Features\Context;

    use Behat\Behat\Context\SnippetAcceptingContext;
    use Behat\MinkExtension\Context\MinkContext;

    use Symfony\Component\HttpKernel\KernelInterface;

    /**
     * Defines application features from the specific context.
     */
    class FeatureContext extends MinkContext implements SnippetAcceptingContext
    {

        use KernelDictionary;

        const DEBUG = true;  // make true if your tests have any troubles
        const LOADFIXTURES = true;  // activate when the project has fixtures

        /**

            }
            $output = new BufferedOutput();
            $exitCode = $this->application->run(new StringInput($command), $output);

            if (self::DEBUG || $exitCode) {
                print sprintf("%s\t[exitCode=%d]\n%s", $command, $exitCode, $output->fetch());
            }
        }

        /**

    }

And this is my feature file:

Feature: Free Registration

  Background:
    Given database is clean

  Scenario: Free user register
    Given I am on "/en/register"
    When I fill in the following:
      | fos_user_registration_form[email] | maurocasula@gmail.com |
      | fos_user_registration_form[profile][name] | NAME LASTNAME |
      | fos_user_registration_form[plainPassword][first] | pass |
      | fos_user_registration_form[plainPassword][second] | pass |
    And I press "_submit"
    And show last response
    Then I should see "app.registration.confirmed_free"
    And the response status code should be 200

Answer 1

Finally I found the problem.

There were two forms in the registration page. Removing the second form the test pass without problems.
