Testing a symfony 2.1 project using behat and mink - symfony

Question

I'm trying to use Behat and Mink to test a symfony 2.1 project.
My FeatureContext.php:
<?php
use Behat\Behat\Context\ClosuredContextInterface,
Behat\Behat\Context\BehatContext,
Behat\Behat\Exception\PendingException,
Behat\Behat\Context\Step;
use Behat\Gherkin\Node\PyStringNode,
Behat\Gherkin\Node\TableNode;
use Behat\MinkExtension\Context\MinkContext;
//
// Require 3rd-party libraries here:
//
// require_once 'PHPUnit/Autoload.php';
// require_once 'PHPUnit/Framework/Assert/Functions.php';
//
/**
* Features context.
*/
class FeatureContext extends Behat\MinkExtension\Context\MinkContext {
/**
* Initializes context.
* Every scenario gets it's own context object.
*
* #param array $parameters context parameters (set them up through behat.yml)
*/
public function __construct(array $parameters)
{
// Initialize your context here
}
//
// Place your definition and hook methods here:
//
// /**
// * #Given /^I have done something with "([^"]*)"$/
// */
// public function iHaveDoneSomethingWith($argument)
// {
// doSomethingWith($argument);
// }
//
}

In order to login
As a user
I need to be able to validate the username and password
Scenario: Link to login page # features/login.feature:7

Answer 1

Your behat.yml should not be located in app/config/behat.yml , but in your/project/root/behat.yml

Answer 2

Thanks for #Stuart and #spiritoo answers here.
Firstly, move the behat.yml from /config to project root.
Secondly, content for the behat.yml:
default:
suites:
my_suite:
contexts:
- FeatureContext
extensions:
Behat\Symfony2Extension: ~
Behat\MinkExtension:
base_url: http://en.wikipedia.org
goutte: ~
sessions:
default:
symfony2: ~
Finally, in project root, run:
vendor/bin/behat features/{YOUR TEST FILE HERE}
My composer.json file:
"require-dev": {
"behat/behat": "^3.3",
"behat/mink": "^1.7",
"behat/mink-extension": "^2.2",
"behat/mink-browserkit-driver": "^1.3",
"behat/mink-goutte-driver": "^1.2",
"behat/symfony2-extension": "^2.1",
"behat/mink-selenium2-driver": "^1.3"
}
